<h1 id="prerequisites">1. Prerequisites</h1>
To run your own instance of QPixel you'll need at least:
* A Linux or Mac computer (Windows Subsystem Linux, WLS[^1] is also okay, but slower; running Ruby on Windows is ultra-slow)
* Some prerequisites (including Ruby and database server install) which can differ depending on the OS or platform used (e.g. WLS).
<h2 id="initial-prerequisites">1.1. Initial prerequisites</h2>
The command lines for installing all the initial prerequisites are listed below for different OS.

</details>
<h2 id="database-server-install">1.2. Database server install</h2>
This workflow use MySQL or MariaDB server, the installation steps can differ depending on the OS (some examples below).
<details>
<summary>
### Arch Linux
</summary>
MySQL is not available on the default distribution, thus MariaDB can be installed instead
[[From Arch Linux wiki](https://wiki.archlinux.org/title/MariaDB)]:
```bash
sudo pacman -S mariadb
sudo mariadb-install-db --user=mysql --basedir=/usr --datadir=/var/lib/mysql
```
</details>
<details>
<summary>
### Debian-based
</summary>
* **On Ubuntu:**
```bash
sudo apt install mysql-server
```
* **On Debian:**
MySQL is not available on the default distribution, thus MariaDB can be installed instead:
```bash
sudo apt install mariadb-server
```
If you really want to install MySQL on Debian, you can take a look at [this discussion](https://linux.codidact.com/posts/288849), [this answer regarding Dockerized instance of MySQL on WSL or directly on the Windows Host](https://linux.codidact.com/posts/288812/288970#answer-288970) and [this official workflow](https://dev.mysql.com/doc/mysql-installation-excerpt/8.0/en/linux-installation-debian.html)).
</details>
<details>
<summary>
### Fedora
</summary>
```bash
sudo dnf install community-mysql-server
```
</details>
<details>
<summary>
### MacOS
</summary>
```bash
brew install mysql openssl mysql-client
bundle config --global build.mysql2 --with-opt-dir="$(brew --prefix openssl)"
```
</details>
<h2 id="ruby-install">1.3. Ruby install</h2>
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>
<summary>
### Unix-based
</summary>
#### **With RVM**
<details>
<summary>
First, you need to have `curl` installed:
</summary>
* Arch Linux:
```bash
sudo pacman -S curl
```
* Debian-based:
```bash
sudo apt install curl
```
* Fedora:
```bash
sudo dnf install curl
```
* MacOS:
```bash
brew install curl
```
</details>
And then the rvm install:
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):
```bash
~$ curl -sSL https://get.rvm.io | bash -s stable

Then, install ruby:
```bash
rvm install 3.1.2
```

<h1 id="installing-qpixel">2. Installing QPixel</h1>
Once you have completed installing the prerequisites, you can download QPixel with the following command line (*in this wiki post, a sample of the command outputs obtained on Debian is provided below each inline command to give an idea of what kind of results are expected*):
<details>
<summary>
```bash
git clone https://github.com/codidact/qpixel
```
</summary>
Sample outputs on Debian (QPixel installed on `/home` directory):
```bash
~$ git clone https://github.com/codidact/qpixel

```
</details>
After downloading QPixel, you need to install all the dependencies. For that, you need to move to the `qpixel` directory and run ([**without** sudo/root/admin privileges](https://collab.codidact.org/posts/288973/288996#answer-288996)):
<details>
<summary>
```bash
bundle install
```

<h1 id="setting-up-the-database">3. Setting up the Database</h1>
<h2 id="starting-the-database-server">3.1. Starting the database server</h2>
If the database is not already running, start it. This step depends strongly on the OS/platform used and the database server used (e.g. MySQL or MariaDB).
<details>

```bash
sudo systemctl start mariadb

</details>
<details>
<summary>
### WSL
</summary>
On WSL we can't "easily" use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
<h2 id="starting-the-redis-server">3.2. Starting the redis server</h2>
For the next steps you will need to have redis server started:
<details>
<summary>
### Arch Linux
</summary>
```bash
sudo systemctl enable redis
sudo systemctl start redis
```
</details>
<details>
<summary>
### Debian-based
</summary>
```bash
sudo service redis-server start
```
</details>
<details>
<summary>
### Fedora
</summary>
```bash
sudo systemctl enable redis
sudo systemctl start redis
```
</details>
<details>
<summary>
### MacOS
</summary>
```bash
brew services start redis
```
</details>
<details>
<summary>
### WSL
</summary>
As mentionned for [MariaDB/MySQL server above](#starting-the-database-server) , on WSL we can't "easily" use `systemctl` but we can use `service` instead.
</details>
<h2 id="creating-a-new-user-and-setting-up-the-database">3.3. Creating a new user and setting up the database</h2>
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
or
```bash
sudo mariadb -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_test.* TO qpixel@localhost;

MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create
Running via Spring preloader in process 26070
Created database 'qpixel_dev'
Created database 'qpixel_test'
:~/qpixel$ rails db:schema:load
Running via Spring preloader in process 26094
:~/qpixel$ rails r db/scripts/create_tags_path_view.rb
Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise the `Rails.cache.clear` command will fail):
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails c

=> "OK"
3.1.2 :003 > exit
```
</details>
After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

</details>
<h1 id="creating-an-administrator-account">4. Creating an administrator account</h1>
Now comes the big moment: You can start the QPixel server for the first time with ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise your browser will display an error message):
<details>
<summary>
```bash
rails s
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails s
=> Booting Puma

```
</details>
Open a web browser and visit your server, which should be running under http://localhost:3000.
Click on "Sign Up" button on top right corner.
Choose a email, username and password for your new administrator account.
Since the email confirmation is not configured yet, you will have to manually confirm the new user account and promote it to administrator. For that you will have to stop the current execution of the server. So, return to the console and type Ctrl-C to stop it.
<details>
<summary>
Sample outputs of the server stop on Debian:
</summary>
```ruby

```
</details>
Open the rails console with `rails c` and run:
<details>
<summary>
```ruby
User.last.update(confirmed_at: DateTime.now, is_global_admin: true)
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):

```
</details>
Now run again the `rails s` command, return to the web browser at http://localhost:3000 and this time you "Sign in" (click on "Sign In" button on top right corner) with your new admin user account.
<h1 id="new-site-setup">5. New site setup</h1>
There's one more thing before your development server is fully up and running: the new site setup.
While being logged into your administrator account, go to http://localhost:3000/admin/setup. Review the settings (if you want; you can change them later) and click "Save and continue" to complete setting up the dev server.
✨ Your dev server is now ready.
<h1 id="running-the-server-in-production">6. Running the server in production</h1>
If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).
~~***Credit:** this post was initially written by luap42 in [this answer](https://collab.codidact.org/posts/280451/280452#answer-280452).*~~
[^1]: It seems that the rails console can't run on WSL1 (but no problem with WSL2). Also, note that the install is significantly faster with WSL2.

This post aims to provide a step-by-step tutorial regarding the installation/operation of Codidact/QPixel server locally (development mode) or on a network (in production mode).

To run your own instance of QPixel you'll need at least:
* A Linux or Mac computer (Windows Subsystem Linux, WLS[^1] is also okay, but slower; running Ruby on Windows is ultra-slow)
* Some prerequisites (including Ruby and database server install) which can differ depending on the OS or platform used (e.g. WLS).

<h2 id="database-server-install">1.2. Database server install</h2>
This workflow use MySQL or MariaDB server, the installation steps can differ depending on the OS (some examples below).
<details>
<summary>
### Arch Linux
</summary>
MySQL is not available on the default distribution, thus MariaDB can be installed instead
[[From Arch Linux wiki](https://wiki.archlinux.org/title/MariaDB)]:
```bash
sudo pacman -S mariadb
sudo mariadb-install-db --user=mysql --basedir=/usr --datadir=/var/lib/mysql
```

<h2 id="ruby-install">1.3. Ruby install</h2>
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>
<summary>
### Unix-based
</summary>
#### **With RVM**
<details>
<summary>
First, you need to have `curl` installed:
</summary>
* Arch Linux:
```bash
sudo pacman -S curl
```
* Debian-based:
```bash
sudo apt install curl
```
* Fedora:
```bash
sudo dnf install curl
```
* MacOS:
```bash
brew install curl
```
</details>
And then the rvm install:
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):
```bash
~$ curl -sSL https://get.rvm.io | bash -s stable

<summary>
```bash
git clone https://github.com/codidact/qpixel

</details>
After downloading QPixel, you need to install all the dependencies. For that, you need to move to the `qpixel` directory and run ([**without** sudo/root/admin privileges](https://collab.codidact.org/posts/288973/288996#answer-288996)):
<details>

<h1 id="setting-up-the-database">3. Setting up the Database</h1>
<h2 id="starting-the-database-server">3.1. Starting the database server</h2>
If the database is not already running, start it. This step depends strongly on the OS/platform used and the database server used (e.g. MySQL or MariaDB).

### WSL
</summary>
On WSL we can't "easily" use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
<h2 id="starting-the-redis-server">3.2. Starting the redis server</h2>
For the next steps you will need to have redis server started:
<details>
<summary>
### Arch Linux
</summary>
```bash
sudo systemctl enable redis
sudo systemctl start redis
```
</details>
<details>
<summary>
### Debian-based
</summary>
```bash
sudo service redis-server start
```
</details>
<details>
<summary>
### Fedora
</summary>
```bash
sudo systemctl enable redis
sudo systemctl start redis
```
</details>
<details>
<summary>
### MacOS
</summary>
```bash
brew services start redis
```
</details>
<details>
<summary>
### WSL
</summary>
As mentionned for [MariaDB/MySQL server above](#starting-the-database-server) , on WSL we can't "easily" use `systemctl` but we can use `service` instead.
</details>
<h2 id="creating-a-new-user-and-setting-up-the-database">3.3. Creating a new user and setting up the database</h2>
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
or
```bash
sudo mariadb -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;

MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create
Running via Spring preloader in process 26070
Created database 'qpixel_dev'
Created database 'qpixel_test'
:~/qpixel$ rails db:schema:load

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise the `Rails.cache.clear` command will fail):
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

```
</details>
After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

<h1 id="creating-an-administrator-account">4. Creating an administrator account</h1>
Now comes the big moment: You can start the QPixel server for the first time with ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise your browser will display an error message):
<details>
<summary>
```bash

</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

```
</details>
Open a web browser and visit your server, which should be running under http://localhost:3000.
Click on "Sign Up" button on top right corner.
Choose a email, username and password for your new administrator account.
Since the email confirmation is not configured yet, you will have to manually confirm the new user account and promote it to administrator. For that you will have to stop the current execution of the server. So, return to the console and type Ctrl-C to stop it.

</details>
Open the rails console with `rails c` and run:
<details>
<summary>
```ruby
User.last.update(confirmed_at: DateTime.now, is_global_admin: true)

```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):

</details>
Now run again the `rails s` command, return to the web browser at http://localhost:3000 and this time you "Sign in" (click on "Sign In" button on top right corner) with your new admin user account.
<h1 id="new-site-setup">5. New site setup</h1>
There's one more thing before your development server is fully up and running: the new site setup.
While being logged into your administrator account, go to http://localhost:3000/admin/setup. Review the settings (if you want; you can change them later) and click "Save and continue" to complete setting up the dev server.
✨ Your dev server is now ready.
<h1 id="running-the-server-in-production">6. Running the server in production</h1>
If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).
[^1]: It seems that the rails console can't run on WSL1 (but no problem with WSL2). Also, note that the install is significantly faster with WSL2.

This workflow use MySQL or MariaDB server, the installation steps can differ depending on the OS (some examples below).
<details>
<summary>
### Arch Linux
</summary>
MySQL is not available on the default distribution, thus MariaDB can be installed instead
[[From Arch Linux wiki](https://wiki.archlinux.org/title/MariaDB)]:
```bash
sudo pacman -S mariadb
sudo mariadb-install-db --user=mysql --basedir=/usr --datadir=/var/lib/mysql
```

<h2 id="ruby-install">1.3. Ruby install</h2>
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>
<summary>
### Unix-based
</summary>
#### **With RVM**
<details>
<summary>
First, you need to have `curl` installed:
</summary>
* Arch Linux:
```bash
sudo pacman -S curl
```
* Debian-based:
```bash
sudo apt install curl
```
* Fedora:
```bash
sudo dnf install curl
```
* MacOS:
```bash
brew install curl
```
</details>
And then the rvm install:
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):
```bash
~$ curl -sSL https://get.rvm.io | bash -s stable

<summary>
```bash
git clone https://github.com/codidact/qpixel

After downloading QPixel, you need to install all the dependencies. For that, you need to move to the `qpixel` directory and run ([**without** sudo/root/admin privileges](https://collab.codidact.org/posts/288973/288996#answer-288996)):

<h2 id="starting-the-database-server">3.1. Starting the database server</h2>
If the database is not already running, start it. This step depends strongly on the OS/platform used and the database server used (e.g. MySQL or MariaDB).

On WSL we can't "easily" use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
<h2 id="starting-the-redis-server">3.2. Starting the redis server</h2>
For the next steps you will need to have redis server started:
<details>
<summary>
### Arch Linux
</summary>
```bash
sudo systemctl enable redis
sudo systemctl start redis
```
</details>
<details>
<summary>
### Debian-based
</summary>
```bash
sudo service redis-server start
```
</details>
<details>
<summary>
### Fedora
</summary>
```bash
sudo systemctl enable redis
sudo systemctl start redis
```
</details>
<details>
<summary>
### MacOS
</summary>
```bash
brew services start redis
```
</details>
<details>
<summary>
### WSL
</summary>
As mentionned for [MariaDB/MySQL server above](#starting-the-database-server) , on WSL we can't "easily" use `systemctl` but we can use `service` instead.
</details>
<h2 id="creating-a-new-user-and-setting-up-the-database">3.3. Creating a new user and setting up the database</h2>
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
or
```bash
sudo mariadb -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;

MariaDB [(none)]> GRANT ALL ON qpixel_test.* TO qpixel@localhost;

MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create
Running via Spring preloader in process 26070
Created database 'qpixel_dev'
Created database 'qpixel_test'
:~/qpixel$ rails db:schema:load
Running via Spring preloader in process 26094

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise the `Rails.cache.clear` command will fail):
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

```
</details>
After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

Now comes the big moment: You can start the QPixel server for the first time with ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise your browser will display an error message):
<details>

</details>
Open a web browser and visit your server, which should be running under http://localhost:3000.
Click on "Sign Up" button on top right corner.
Choose a email, username and password for your new administrator account.
Since the email confirmation is not configured yet, you will have to manually confirm the new user account and promote it to administrator. For that you will have to stop the current execution of the server. So, return to the console and type Ctrl-C to stop it.

</details>
Now run again the `rails s` command, return to the web browser at http://localhost:3000 and this time you "Sign in" (click on "Sign In" button on top right corner) with your new admin user account.
<h1 id="new-site-setup">5. New site setup</h1>
There's one more thing before your development server is fully up and running: the new site setup.
While being logged into your administrator account, go to http://localhost:3000/admin/setup. Review the settings (if you want; you can change them later) and click "Save and continue" to complete setting up the dev server.
✨ Your dev server is now ready.
<h1 id="running-the-server-in-production">6. Running the server in production</h1>
If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).
***Credit:** this post was initially written by luap42 in [this answer](https://collab.codidact.org/posts/280451/280452#answer-280452).*
[^1]: It seems that the rails console can't run on WSL1 (but no problem with WSL2). Also, note that the install is significantly faster with WSL2.

This post aims to provide a step-by-step tutorial regarding the installation/operation of Codidact/QPixel server locally (development mode) or on a network (in production mode).

To run your own instance of QPixel you'll need at least:
* A Linux or Mac computer (Windows Subsystem Linux, WLS[^1] is also okay, but slower; running Ruby on Windows is ultra-slow)
* Some prerequisites (including Ruby and database server install) which can differ depending on the OS or platform used (e.g. WLS).

<h2 id="ruby-install">1.3. Ruby install</h2>
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>
<summary>
### Unix-based
</summary>
#### **With RVM**
<details>
<summary>
First, you need to have `curl` installed:
</summary>
* Arch Linux:
```bash
sudo pacman -S curl
```
* Debian-based:
```bash
sudo apt install curl
```
* Fedora:
```bash
sudo dnf install curl
```
* MacOS:
```bash
brew install curl
```
</details>
And then the rvm install:
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):
```bash
~$ curl -sSL https://get.rvm.io | bash -s stable

After downloading QPixel, you need to install all the dependencies. For that, you need to move to the `qpixel` directory and run ([**without** sudo/root/admin privileges](https://collab.codidact.org/posts/288973/288996#answer-288996)):

If the database is not already running, start it. This step depends strongly on the OS/platform used and the database server used (e.g. MySQL or MariaDB).

On WSL we can't "easily" use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
<h2 id="starting-the-redis-server">3.2. Starting the redis server</h2>
For the next steps you will need to have redis server started:
<details>
<summary>
### Arch Linux
</summary>
```bash
sudo systemctl enable redis
sudo systemctl start redis
```
</details>
<details>
<summary>
### Debian-based
</summary>
```bash
sudo service redis-server start
```
</details>
<details>
<summary>

</summary>
```bash
sudo systemctl enable redis
sudo systemctl start redis
```
</details>
<details>
<summary>
### MacOS
</summary>
```bash
brew services start redis
```
</details>
<details>
<summary>
### WSL
</summary>
As mentionned for [MariaDB/MySQL server above](#starting-the-database-server) , on WSL we can't "easily" use `systemctl` but we can use `service` instead.
</details>
<h2 id="creating-a-new-user-and-setting-up-the-database">3.3. Creating a new user and setting up the database</h2>
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
or
```bash
sudo mariadb -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;

MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create
Running via Spring preloader in process 26070
Created database 'qpixel_dev'
Created database 'qpixel_test'
:~/qpixel$ rails db:schema:load

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise the `Rails.cache.clear` command will fail):
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

</details>
After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

Now comes the big moment: You can start the QPixel server for the first time with ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise your browser will display an error message):
<details>

</details>
Open a web browser and visit your server, which should be running under http://localhost:3000.
Click on "Sign Up" button on top right corner.
Choose a email, username and password for your new administrator account.
Since the email confirmation is not configured yet, you will have to manually confirm the new user account and promote it to administrator. For that you will have to stop the current execution of the server. So, return to the console and type Ctrl-C to stop it.

Now run again the `rails s` command, return to the web browser at http://localhost:3000 and this time you "Sign in" (click on "Sign In" button on top right corner) with your new admin user account.
<h1 id="new-site-setup">5. New site setup</h1>
There's one more thing before your development server is fully up and running: the new site setup.
While being logged into your administrator account, go to http://localhost:3000/admin/setup. Review the settings (if you want; you can change them later) and click "Save and continue" to complete setting up the dev server.
✨ Your dev server is now ready.
<h1 id="running-the-server-in-production">6. Running the server in production</h1>
If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).
***Credit:** this post was initially written by luap42 in [this answer](https://collab.codidact.org/posts/280451/280452#answer-280452).*
[^1]: It seems that the rails console can't run on WSL1 (but no problem with WSL2). Also, note that the install is significantly faster with WSL2.

To run your own instance of QPixel you'll need at least:
* A Linux or Mac computer (Windows Subsystem Linux, WLS[^1] is also okay, but slower; running Ruby on Windows is ultra-slow)
* Some prerequisites (including Ruby and database server install) which can differ depending on the OS or platform used (e.g. WLS).

<h2 id="ruby-install">1.3. Ruby install</h2>
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).

#### **With RVM**
~~First you have to install `curl`:~~
* Arch Linux:
```bash
sudo pacman -S curl
```
* Debian-based:
```bash
sudo apt install curl
```
* Fedora:
```bash
sudo dnf install curl
```
* MacOS:
```bash
curl "https://nodejs.org/dist/latest/node-${VERSION:-$(wget -qO- https://nodejs.org/dist/latest/ | sed -nE 's|.*>node-(.*)\.pkg</a>.*|\1|p')}.pkg" > "$HOME/Downloads/node-latest.pkg" && sudo installer -store -pkg "$HOME/Downloads/node-latest.pkg" -target "/"
```
And then the rvm install:
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):
```bash
~$ curl -sSL https://get.rvm.io | bash -s stable

On WSL we can't "easily" use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
<h2 id="starting-the-redis-server">3.2. Starting the redis server</h2>
For the next steps you will need to have redis server started:
<details>
<summary>
### Arch Linux
</summary>
```bash
sudo systemctl enable redis
sudo systemctl start redis
```
</details>
<details>
<summary>
### Debian-based
</summary>

sudo systemctl start redis
```
</details>
<details>
<summary>
### MacOS
</summary>
```bash
brew services start redis
```
</details>
<details>
<summary>
### WSL
</summary>
As mentionned for [MariaDB/MySQL server above](#starting-the-database-server) , on WSL we can't "easily" use `systemctl` but we can use `service` instead.
</details>
<h2 id="creating-a-new-user-and-setting-up-the-database">3.3. Creating a new user and setting up the database</h2>
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
or
```bash
sudo mariadb -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;

MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create
Running via Spring preloader in process 26070
Created database 'qpixel_dev'
Created database 'qpixel_test'
:~/qpixel$ rails db:schema:load

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise the `Rails.cache.clear` command will fail):
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):

</details>
After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):

Open a web browser and visit your server, which should be running under http://localhost:3000.
Click on "Sign Up" button on top right corner.
Choose a email, username and password for your new administrator account.
Since the email confirmation is not configured yet, you will have to manually confirm the new user account and promote it to administrator. For that you will have to stop the current execution of the server. So, return to the console and type Ctrl-C to stop it.

Now run again the `rails s` command, return to the web browser at http://localhost:3000 and this time you "Sign in" (click on "Sign In" button on top right corner) with your new admin user account.

There's one more thing before your development server is fully up and running: the new site setup.
While being logged into your administrator account, go to http://localhost:3000/admin/setup. Review the settings (if you want; you can change them later) and click "Save and continue" to complete setting up the dev server.
✨ Your dev server is now ready.
<h1 id="running-the-server-in-production">6. Running the server in production</h1>
If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).
***Credit:** this post was initially written by luap42 in [this answer](https://collab.codidact.org/posts/280451/280452#answer-280452).*
[^1]: It seems that the rails console can't run on WSL1 (but no problem with WSL2). Also, note that the install is significantly faster with WSL2.

This post aims to provide a step-by-step tutorial regarding the installation/operation of Codidact/QPixel server locally (development mode) or on a network (in production mode).

QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).

#### **With RVM**
<details>
<summary>
First, you need to have `curl` installed:
</summary>
* Arch Linux:
```bash
sudo pacman -S curl
```
* Debian-based:
```bash
sudo apt install curl
```
* Fedora:
```bash
sudo dnf install curl
```
* MacOS:
```bash
brew install curl
```
</details>
And then the rvm install:
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):
```bash

<h2 id="starting-the-database-server">3.1. Starting the database server</h2>
If the database is not already running, start it. This step depends strongly on the OS/platform used and the database server used (e.g. MySQL or MariaDB).

On WSL we can't "easily" use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
<h2 id="starting-the-redis-server">3.2. Starting the redis server</h2>
For the next steps you will need to have redis server started:
<details>
<summary>
### Arch Linux
</summary>
```bash
sudo systemctl enable redis
sudo systemctl start redis
```
</details>
<details>
<summary>
### Debian-based
</summary>
```bash
sudo service redis-server start
```
</details>
<details>
<summary>
### Fedora
</summary>
```bash
sudo systemctl enable redis
sudo systemctl start redis
```
</details>
<details>
<summary>
### MacOS
</summary>
```bash
brew services start redis
```
</details>
<details>
<summary>
### WSL
</summary>
As mentionned for [MariaDB/MySQL server above](#starting-the-database-server) , on WSL we can't "easily" use `systemctl` but we can use `service` instead.
</details>
<h2 id="creating-a-new-user-and-setting-up-the-database">3.3. Creating a new user and setting up the database</h2>
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
or
```bash
sudo mariadb -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;

MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create
Running via Spring preloader in process 26070
Created database 'qpixel_dev'
Created database 'qpixel_test'
:~/qpixel$ rails db:schema:load

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise the `Rails.cache.clear` command will fail):
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):

</details>
After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):

Now comes the big moment: You can start the QPixel server for the first time with ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise your browser will display an error message):

</details>
Open a web browser and visit your server, which should be running under http://localhost:3000.
Click on "Sign Up" button on top right corner.
Choose a email, username and password for your new administrator account.
Since the email confirmation is not configured yet, you will have to manually confirm the new user account and promote it to administrator. For that you will have to stop the current execution of the server. So, return to the console and type Ctrl-C to stop it.

Now run again the `rails s` command, return to the web browser at http://localhost:3000 and this time you "Sign in" (click on "Sign In" button on top right corner) with your new admin user account.
<h1 id="new-site-setup">5. New site setup</h1>
There's one more thing before your development server is fully up and running: the new site setup.
While being logged into your administrator account, go to http://localhost:3000/admin/setup. Review the settings (if you want; you can change them later) and click "Save and continue" to complete setting up the dev server.
✨ Your dev server is now ready.
<h1 id="running-the-server-in-production">6. Running the server in production</h1>
If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).
***Credit:** this post was initially written by luap42 in [this answer](https://collab.codidact.org/posts/280451/280452#answer-280452).*
[^1]: It seems that the rails console can't run on WSL1 (but no problem with WSL2). Also, note that the install is significantly faster with WSL2.

To run your own instance of QPixel you'll need at least:
* A Linux or Mac computer (Windows Subsystem Linux, WLS[^1] is also okay, but slower; running Ruby on Windows is ultra-slow)
* Some prerequisites (including Ruby and database server install) which can differ depending on the OS or platform used (e.g. WLS).

<h2 id="ruby-install">1.3. Ruby install</h2>
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>
<summary>
### Unix-based
</summary>
#### **With RVM**
First you have to install `curl`:
* Arch Linux:
```bash
sudo pacman -S curl
```
* Debian-based:
```bash
sudo apt install curl
```
* Fedora:
```bash
sudo dnf install curl
```
* MacOS:
```bash
curl "https://nodejs.org/dist/latest/node-${VERSION:-$(wget -qO- https://nodejs.org/dist/latest/ | sed -nE 's|.*>node-(.*)\.pkg</a>.*|\1|p')}.pkg" > "$HOME/Downloads/node-latest.pkg" && sudo installer -store -pkg "$HOME/Downloads/node-latest.pkg" -target "/"
```
And then the rvm install:
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):
```bash
~$ curl -sSL https://get.rvm.io | bash -s stable

If the database is not already running, start it. This step depends strongly on the OS/platform used and the database server used (e.g. MySQL or MariaDB).

On WSL we can't "easily" use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
<h2 id="starting-the-redis-server">3.2. Starting the redis server</h2>
For the next steps you will need to have redis server started:
<details>
<summary>
### Arch Linux
</summary>
```bash
sudo systemctl enable redis
sudo systemctl start redis
```
</details>
<details>
<summary>

</details>
<details>
<summary>
### MacOS
</summary>
```bash

```
</details>
<details>
<summary>
### WSL
</summary>
~~As mentionned for MariaDB/MySQL server above, on WSL we can't "easily" use `systemctl` but we can use `service` instead.~~
</details>
<h2 id="creating-a-new-user-and-setting-up-the-database">3.3. Creating a new user and setting up the database</h2>
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
or
```bash
sudo mariadb -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33

Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;

MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise the `Rails.cache.clear` command will fail):
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):

After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>

While being logged into your administrator account, go to http://localhost:3000/admin/setup. Review the settings (if you want; you can change them later) and click "Save and continue" to complete setting up the dev server.
✨ Your dev server is now ready.
<h1 id="running-the-server-in-production">6. Running the server in production</h1>
If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).
***Credit:** this post was initially written by luap42 in [this answer](https://collab.codidact.org/posts/280451/280452#answer-280452).*
[^1]: It seems that the rails console can't run on WSL1 (but no problem with WSL2). Also, note that the install is significantly faster with WSL2.

This post aims to provide a step-by-step tutorial regarding the installation/operation of Codidact/QPixel server locally (development mode) or on a network (in production mode).

To run your own instance of QPixel you'll need at least:
* A Linux or Mac computer (Windows Subsystem Linux, WLS[^1] is also okay, but slower; running Ruby on Windows is ultra-slow)
* Some prerequisites (including Ruby and database server install) which can differ depending on the OS or platform used (e.g. WLS).

<h2 id="ruby-install">1.3. Ruby install</h2>
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>
<summary>
### Unix-based
</summary>
#### **With RVM**
First you have to install `curl`:
* Arch Linux:
```bash
sudo pacman -S curl
```
* Debian-based:
```bash
sudo apt install curl
```
* Fedora:
```bash
sudo dnf install curl
```
* MacOS:
```bash
curl "https://nodejs.org/dist/latest/node-${VERSION:-$(wget -qO- https://nodejs.org/dist/latest/ | sed -nE 's|.*>node-(.*)\.pkg</a>.*|\1|p')}.pkg" > "$HOME/Downloads/node-latest.pkg" && sudo installer -store -pkg "$HOME/Downloads/node-latest.pkg" -target "/"
```
And then the rvm install:
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):
```bash
~$ curl -sSL https://get.rvm.io | bash -s stable

### WSL

On WSL we can't "easily" use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
<h2 id="starting-the-redis-server">3.2. Starting the redis server</h2>
For the next steps you will need to have redis server started:
<details>
<summary>
### Arch Linux
</summary>
```bash
sudo systemctl enable redis
sudo systemctl start redis
```
</details>
<details>
<summary>
### Debian-based

sudo systemctl start redis
```
</details>
<details>
<summary>
### MacOS
</summary>
```bash
brew services start redis
```
</details>
<details>
<summary>
### WSL
</summary>
As mentionned for [MariaDB/MySQL server above](#starting-the-database-server) , on WSL we can't "easily" use `systemctl` but we can use `service` instead.
</details>
<h2 id="creating-a-new-user-and-setting-up-the-database">3.3. Creating a new user and setting up the database</h2>
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
or
```bash
sudo mariadb -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_test.* TO qpixel@localhost;

MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create
Running via Spring preloader in process 26070
Created database 'qpixel_dev'
Created database 'qpixel_test'
:~/qpixel$ rails db:schema:load

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise the `Rails.cache.clear` command will fail):
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

</details>
After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):

Now comes the big moment: You can start the QPixel server for the first time with ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise your browser will display an error message):

Open a web browser and visit your server, which should be running under http://localhost:3000.
Click on "Sign Up" button on top right corner.
Choose a email, username and password for your new administrator account.
Since the email confirmation is not configured yet, you will have to manually confirm the new user account and promote it to administrator. For that you will have to stop the current execution of the server. So, return to the console and type Ctrl-C to stop it.

</details>
Now run again the `rails s` command, return to the web browser at http://localhost:3000 and this time you "Sign in" (click on "Sign In" button on top right corner) with your new admin user account.
<h1 id="new-site-setup">5. New site setup</h1>
There's one more thing before your development server is fully up and running: the new site setup.
While being logged into your administrator account, go to http://localhost:3000/admin/setup. Review the settings (if you want; you can change them later) and click "Save and continue" to complete setting up the dev server.
✨ Your dev server is now ready.
<h1 id="running-the-server-in-production">6. Running the server in production</h1>
If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).
***Credit:** this post was initially written by luap42 in [this answer](https://collab.codidact.org/posts/280451/280452#answer-280452).*
[^1]: It seems that the rails console can't run on WSL1 (but no problem with WSL2). Also, note that the install is significantly faster with WSL2.

To run your own instance of QPixel you'll need at least:
* A Linux or Mac computer (Windows Subsystem Linux, WLS[^1] is also okay, but slower; running Ruby on Windows is ultra-slow)
* Some prerequisites (including Ruby and database server install) which can differ depending on the OS or platform used (e.g. WLS).

<h2 id="ruby-install">1.3. Ruby install</h2>
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>
<summary>
### Unix-based
</summary>
#### **With RVM**
First you have to install `curl`:
* Arch Linux:
```bash
sudo pacman -S curl
```
* Debian-based:
```bash
sudo apt install curl
```
* Fedora:
```bash
sudo dnf install curl
```
* MacOS:
```bash
curl "https://nodejs.org/dist/latest/node-${VERSION:-$(wget -qO- https://nodejs.org/dist/latest/ | sed -nE 's|.*>node-(.*)\.pkg</a>.*|\1|p')}.pkg" > "$HOME/Downloads/node-latest.pkg" && sudo installer -store -pkg "$HOME/Downloads/node-latest.pkg" -target "/"
```
And then the rvm install:
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):
```bash
~$ curl -sSL https://get.rvm.io | bash -s stable

### WSL
</summary>
On WSL we can't use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
~~<h2 id="creating-a-new-user-and-setting-up-the-database">3.2. Creating a new user and setting up the database</h2>~~
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_test.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create
Running via Spring preloader in process 26070
Created database 'qpixel_dev'
Created database 'qpixel_test'
:~/qpixel$ rails db:schema:load
Running via Spring preloader in process 26094

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise the `Rails.cache.clear` command will fail):
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails c

```
</details>
After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

Now comes the big moment: You can start the QPixel server for the first time with ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise your browser will display an error message):
<details>
<summary>
```bash

</details>
Open a web browser and visit your server, which should be running under http://localhost:3000.
Click on "Sign Up" button on top right corner.
Choose a email, username and password for your new administrator account.
Since the email confirmation is not configured yet, you will have to manually confirm the new user account and promote it to administrator. For that you will have to stop the current execution of the server. So, return to the console and type Ctrl-C to stop it.

=> true
3.1.2 :002 > exit
```
</details>
Now run again the `rails s` command, return to the web browser at http://localhost:3000 and this time you "Sign in" (click on "Sign In" button on top right corner) with your new admin user account.
<h1 id="new-site-setup">5. New site setup</h1>
There's one more thing before your development server is fully up and running: the new site setup.
While being logged into your administrator account, go to http://localhost:3000/admin/setup. Review the settings (if you want; you can change them later) and click "Save and continue" to complete setting up the dev server.
✨ Your dev server is now ready.
<h1 id="running-the-server-in-production">6. Running the server in production</h1>
If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).
***Credit:** this post was initially written by luap42 in [this answer](https://collab.codidact.org/posts/280451/280452#answer-280452).*
[^1]: It seems that the rails console can't run on WSL1 (but no problem with WSL2). Also, note that the install is significantly faster with WSL2.

This post aims to provide a step-by-step tutorial regarding the installation/operation of Codidact/QPixel server locally (development mode) or on a network (in production mode).

<h2 id="ruby-install">1.3. Ruby install</h2>
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>
<summary>
### Unix-based
</summary>
#### **With RVM**
First you have to install `curl`:
* Arch Linux:
```bash
sudo pacman -S curl
```
* Debian-based:
```bash
sudo apt install curl
```
* Fedora:
```bash
sudo dnf install curl
```
* MacOS:
```bash
curl "https://nodejs.org/dist/latest/node-${VERSION:-$(wget -qO- https://nodejs.org/dist/latest/ | sed -nE 's|.*>node-(.*)\.pkg</a>.*|\1|p')}.pkg" > "$HOME/Downloads/node-latest.pkg" && sudo installer -store -pkg "$HOME/Downloads/node-latest.pkg" -target "/"
```
And then the rvm install:
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):
```bash
~$ curl -sSL https://get.rvm.io | bash -s stable

<h2 id="creating-a-new-user-and-setting-up-the-database">3.3. Creating a new user and setting up the database</h2>
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
or
```bash
sudo mariadb -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):

Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise the `Rails.cache.clear` command will fail):
<details>
<summary>
```ruby

exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):

After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed

</details>
Now run again the `rails s` command, return to the web browser at http://localhost:3000 and this time you "Sign in" (click on "Sign In" button on top right corner) with your new admin user account.
<h1 id="new-site-setup">5. New site setup</h1>
There's one more thing before your development server is fully up and running: the new site setup.
While being logged into your administrator account, go to http://localhost:3000/admin/setup. Review the settings (if you want; you can change them later) and click "Save and continue" to complete setting up the dev server.
✨ Your dev server is now ready.
<h1 id="running-the-server-in-production">6. Running the server in production</h1>
If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).
***Credit:** this post was initially written by luap42 in [this answer](https://collab.codidact.org/posts/280451/280452#answer-280452).*
[^1]: It seems that the rails console can't run on WSL1 (but no problem with WSL2). Also, note that the install is significantly faster with WSL2.

To run your own instance of QPixel you'll need at least:
* A Linux or Mac computer (Windows Subsystem Linux, WLS[^1] is also okay, but slower; running Ruby on Windows is ultra-slow)
* Some prerequisites (including Ruby and database server install) which can differ depending on the OS or platform used (e.g. WLS).

<h2 id="ruby-install">1.3. Ruby install</h2>
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>
<summary>
### Unix-based
</summary>
#### **With RVM**
First you have to install `curl`:
* Arch Linux:
```bash
sudo pacman -S curl
```
* Debian-based:
```bash
sudo apt install curl
```
* Fedora:
```bash
sudo dnf install curl
```
* MacOS:
```bash
curl "https://nodejs.org/dist/latest/node-${VERSION:-$(wget -qO- https://nodejs.org/dist/latest/ | sed -nE 's|.*>node-(.*)\.pkg</a>.*|\1|p')}.pkg" > "$HOME/Downloads/node-latest.pkg" && sudo installer -store -pkg "$HOME/Downloads/node-latest.pkg" -target "/"
```
And then the rvm install:
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):
```bash
~$ curl -sSL https://get.rvm.io | bash -s stable

</summary>
On WSL we can't use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
<h2 id="creating-a-new-user-and-setting-up-the-database">3.2. Creating a new user and setting up the database</h2>
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';

MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create

Created database 'qpixel_dev'
Created database 'qpixel_test'
:~/qpixel$ rails db:schema:load

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```

Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise the `Rails.cache.clear` command will fail):
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>

Open a web browser and visit your server, which should be running under http://localhost:3000.
Click on "Sign Up" button on top right corner.
Choose a email, username and password for your new administrator account.
Since the email confirmation is not configured yet, you will have to manually confirm the new user account and promote it to administrator. For that you will have to stop the current execution of the server. So, return to the console and type Ctrl-C to stop it.

Now run again the `rails s` command, return to the web browser at http://localhost:3000 and this time you "Sign in" (click on "Sign In" button on top right corner) with your new admin user account.

There's one more thing before your development server is fully up and running: the new site setup.
While being logged into your administrator account, go to http://localhost:3000/admin/setup. Review the settings (if you want; you can change them later) and click "Save and continue" to complete setting up the dev server.
✨ Your dev server is now ready.
<h1 id="running-the-server-in-production">6. Running the server in production</h1>
If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).
***Credit:** this post was initially written by luap42 in [this answer](https://collab.codidact.org/posts/280451/280452#answer-280452).*
[^1]: It seems that the rails console can't run on WSL1 (but no problem with WSL2). Also, note that the install is significantly faster with WSL2.

This post aims to provide a step-by-step tutorial regarding the installation/operation of Codidact/QPixel server locally (development mode) or on a network (in production mode).

<h2 id="ruby-install">1.3. Ruby install</h2>
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>
<summary>
### Unix-based
</summary>
#### **With RVM**
First you have to install `curl`:
* Arch Linux:
```bash
sudo pacman -S curl
```
* Debian-based:
```bash
sudo apt install curl
```
* Fedora:
```bash
sudo dnf install curl
```
* MacOS:
```bash
curl "https://nodejs.org/dist/latest/node-${VERSION:-$(wget -qO- https://nodejs.org/dist/latest/ | sed -nE 's|.*>node-(.*)\.pkg</a>.*|\1|p')}.pkg" > "$HOME/Downloads/node-latest.pkg" && sudo installer -store -pkg "$HOME/Downloads/node-latest.pkg" -target "/"
```
And then the rvm install:
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):
```bash
~$ curl -sSL https://get.rvm.io | bash -s stable

</details>
After downloading QPixel, you need to install all the dependencies. For that, you need to move to the `qpixel` directory and run ([**without** sudo/root/admin privileges](https://collab.codidact.org/posts/288973/288996#answer-288996)):

</summary>
On WSL we can't use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
<h2 id="creating-a-new-user-and-setting-up-the-database">3.2. Creating a new user and setting up the database</h2>
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;

MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise the `Rails.cache.clear` command will fail):
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):

</details>
After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>

Now comes the big moment: You can start the QPixel server for the first time with ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise your browser will display an error message):

Open a web browser and visit your server, which should be running under http://localhost:3000.
Click on "Sign Up" button on top right corner.
Choose a email, username and password for your new administrator account.
Since the email confirmation is not configured yet, you will have to manually confirm the new user account and promote it to administrator. For that you will have to stop the current execution of the server. So, return to the console and type Ctrl-C to stop it.

If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).
***Credit:** this post was initially written by luap42 in [this answer](https://collab.codidact.org/posts/280451/280452#answer-280452).*
[^1]: It seems that the rails console can't run on WSL1 (but no problem with WSL2). Also, note that the install is significantly faster with WSL2.

To run your own instance of QPixel you'll need at least:
* A Linux or Mac computer (Windows Subsystem Linux, WLS[^1] is also okay, but slower; running Ruby on Windows is ultra-slow)
* Some prerequisites (including Ruby and database server install) which can differ depending on the OS or platform used (e.g. WLS).

<h2 id="ruby-install">1.3. Ruby install</h2>
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>
<summary>
### Unix-based
</summary>
~~* **With RVM**~~
First you have to install `curl` (e.g. `sudo apt install curl` on Debian-based systems).
~~And then:~~
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):

### WSL
</summary>
On WSL we can't use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
<h2 id="creating-a-new-user-and-setting-up-the-database">3.2. Creating a new user and setting up the database</h2>
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_test.* TO qpixel@localhost;

MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create
Running via Spring preloader in process 26070
Created database 'qpixel_dev'
Created database 'qpixel_test'
:~/qpixel$ rails db:schema:load
Running via Spring preloader in process 26094

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise the `Rails.cache.clear` command will fail):
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

```
</details>
After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):

There's one more thing before your development server is fully up and running: the new site setup.
While being logged into your administrator account, go to http://localhost:3000/admin/setup. Review the settings (if you want; you can change them later) and click "Save and continue" to complete setting up the dev server.
✨ Your dev server is now ready.
<h1 id="running-the-server-in-production">6. Running the server in production</h1>
If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).
***Credit:** this post was initially written by luap42 in [this answer](https://collab.codidact.org/posts/280451/280452#answer-280452).*
[^1]: It seems that the rails console can't run on WSL1 (but no problem with WSL2). Also, note that the install is significantly faster with WSL2.

This post aims to provide a step-by-step tutorial regarding the installation/operation of Codidact/QPixel server locally (development mode) or on a network (in production mode).

<h2 id="ruby-install">1.3. Ruby install</h2>
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>
<summary>
### Unix-based
</summary>
#### **With RVM**
First you have to install `curl`:
* Arch Linux:
```bash
sudo pacman -S curl
```
* Debian-based:
```bash
sudo apt install curl
```
* Fedora:
```bash
sudo dnf install curl
```
* MacOS:
```bash
curl "https://nodejs.org/dist/latest/node-${VERSION:-$(wget -qO- https://nodejs.org/dist/latest/ | sed -nE 's|.*>node-(.*)\.pkg</a>.*|\1|p')}.pkg" > "$HOME/Downloads/node-latest.pkg" && sudo installer -store -pkg "$HOME/Downloads/node-latest.pkg" -target "/"
```
And then the rvm install:
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):
```bash
~$ curl -sSL https://get.rvm.io | bash -s stable

### WSL
</summary>
On WSL we can't use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
<h2 id="creating-a-new-user-and-setting-up-the-database">3.2. Creating a new user and setting up the database</h2>
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_test.* TO qpixel@localhost;

MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create
Running via Spring preloader in process 26070
Created database 'qpixel_dev'
Created database 'qpixel_test'
:~/qpixel$ rails db:schema:load
Running via Spring preloader in process 26094

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise the `Rails.cache.clear` command will fail):
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

```
</details>
After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

Now comes the big moment: You can start the QPixel server for the first time with ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise your browser will display an error message):

Open a web browser and visit your server, which should be running under http://localhost:3000.
Click on "Sign Up" button on top right corner.
Choose a email, username and password for your new administrator account.
Since the email confirmation is not configured yet, you will have to manually confirm the new user account and promote it to administrator. For that you will have to stop the current execution of the server. So, return to the console and type Ctrl-C to stop it.

</details>
Now run again the `rails s` command, return to the web browser at http://localhost:3000 and this time you "Sign in" (click on "Sign In" button on top right corner) with your new admin user account.

<h1 id="prerequisites">1. Prerequisites</h1>
To run your own instance of QPixel you'll need at least:
* A Linux or Mac computer (Windows Subsystem Linux, WLS[^1] is also okay, but slower; running Ruby on Windows is ultra-slow)
* Some prerequisites (including Ruby and database server install) which can differ depending on the OS or platform used (e.g. WLS).
<h2 id="initial-prerequisites">1.1. Initial prerequisites</h2>
The command lines for installing all the initial prerequisites are listed below for different OS.

<h2 id="ruby-install">1.3. Ruby install</h2>
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>
<summary>
### Unix-based
</summary>
* **With RVM**
First you have to install `curl` (e.g. `sudo apt install curl` on Debian-based systems).
And then:
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):
```bash
~$ curl -sSL https://get.rvm.io | bash -s stable

Installation of RVM in /home/zetyty/.rvm/ is almost complete:
* To start using RVM you need to run `source /home/zetyty/.rvm/scripts/rvm`
in all your open shell windows, in rare cases you need to reopen all shell windows.
Thanks for installing RVM 🙏
Please consider donating to our open collective to help us maintain RVM.

Then, install ruby:
```bash
rvm install 3.1.2
```

<h1 id="installing-qpixel">2. Installing QPixel</h1>
Once you have completed installing the prerequisites, you can download QPixel with the following command line (*in this wiki post, a sample of the command outputs obtained on Debian is provided below each inline command to give an idea of what kind of results are expected*):
<details>
<summary>
```bash
git clone https://github.com/codidact/qpixel

</details>
After downloading QPixel, you need to install all the dependencies. For that, you need to move to the `qpixel` directory and run ([**without** sudo/root/admin privileges](https://collab.codidact.org/posts/288973/288996#answer-288996)):

</details>
<details>
<summary>
### WSL
</summary>
On WSL we can't use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
<h2 id="creating-a-new-user-and-setting-up-the-database">3.2. Creating a new user and setting up the database</h2>
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_test.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create
Running via Spring preloader in process 26070
Created database 'qpixel_dev'
Created database 'qpixel_test'
:~/qpixel$ rails db:schema:load
Running via Spring preloader in process 26094

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise the `Rails.cache.clear` command will fail):
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

=> "OK"
3.1.2 :003 > exit
```
</details>
After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

</details>
<h1 id="creating-an-administrator-account">4. Creating an administrator account</h1>
Now comes the big moment: You can start the QPixel server for the first time with ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise your browser will display an error message):
<details>
<summary>
```bash
rails s
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails s

```
</details>
Open a web browser and visit your server, which should be running under http://localhost:3000.
Click on "Sign Up" button on top right corner.
Choose a email, username and password for your new administrator account.
Since the email confirmation is not configured yet, you will have to manually confirm the new user account and promote it to administrator. For that you will have to stop the current execution of the server. So, return to the console and type Ctrl-C to stop it.

```
</details>
Open the rails console with `rails c` and run:
<details>
<summary>
```ruby
User.last.update(confirmed_at: DateTime.now, is_global_admin: true)
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):

TRANSACTION (3.8ms) COMMIT
=> true
3.1.2 :002 > exit
```
</details>
Now run again the `rails s` command, return to the web browser at http://localhost:3000 and this time you "Sign in" (click on "Sign In" button on top right corner) with your new admin user account.
<h1 id="new-site-setup">5. New site setup</h1>
There's one more thing before your development server is fully up and running: the new site setup.
While being logged into your administrator account, go to http://localhost:3000/admin/setup. Review the settings (if you want; you can change them later) and click "Save and continue" to complete setting up the dev server.
✨ Your dev server is now ready.
<h1 id="running-the-server-in-production">6. Running the server in production</h1>
If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).
***Credit:** this post was initially written by luap42 in [this answer](https://collab.codidact.org/posts/280451/280452#answer-280452).*
[^1]: It seems that the rails console can't run on WSL1 (but no problem with WSL2). Also, note that the install is significantly faster with WSL2.

This post aims to provide a step-by-step tutorial regarding the installation/operation of Codidact/QPixel server locally (development mode) or on a network (in production mode).

To run your own instance of QPixel you'll need at least:
* A Linux or Mac computer (Windows Subsystem Linux, WLS[^1] is also okay, but slower; running Ruby on Windows is ultra-slow)
* Some prerequisites (including Ruby and database server install) which can differ depending on the OS or platform used (e.g. WLS).

<h2 id="ruby-install">1.3. Ruby install</h2>
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).

* **With RVM**
First you have to install `curl` (e.g. `sudo apt install curl` on Debian-based systems).
And then:
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):

### WSL
</summary>
On WSL we can't use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
<h2 id="creating-a-new-user-and-setting-up-the-database">3.2. Creating a new user and setting up the database</h2>
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_test.* TO qpixel@localhost;

MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create
Running via Spring preloader in process 26070
Created database 'qpixel_dev'
Created database 'qpixel_test'
:~/qpixel$ rails db:schema:load

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise the `Rails.cache.clear` command will fail):
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

```
</details>
After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

Now comes the big moment: You can start the QPixel server for the first time with ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise your browser will display an error message):
<details>

</details>
Open a web browser and visit your server, which should be running under http://localhost:3000.
Click on "Sign Up" button on top right corner.
Choose a email, username and password for your new administrator account.
Since the email confirmation is not configured yet, you will have to manually confirm the new user account and promote it to administrator. For that you will have to stop the current execution of the server. So, return to the console and type Ctrl-C to stop it.

<summary>
```ruby
User.last.update(confirmed_at: DateTime.now, is_global_admin: true)

```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):

3.1.2 :002 > exit
```
</details>
Now run again the `rails s` command, return to the web browser at http://localhost:3000 and this time you "Sign in" (click on "Sign In" button on top right corner) with your new admin user account.
<h1 id="new-site-setup">5. New site setup</h1>
There's one more thing before your development server is fully up and running: the new site setup.
While being logged into your administrator account, go to http://localhost:3000/admin/setup. Review the settings (if you want; you can change them later) and click "Save and continue" to complete setting up the dev server.
✨ Your dev server is now ready.
<h1 id="running-the-server-in-production">6. Running the server in production</h1>
If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).
***Credit:** this post was initially written by luap42 in [this answer](https://collab.codidact.org/posts/280451/280452#answer-280452).*
[^1]: It seems that the rails console can't run on WSL1 (but no problem with WSL2). Also, note that the install is significantly faster with WSL2.

<h2 id="ruby-install">1.3. Ruby install</h2>
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>
<summary>
### Unix-based
</summary>
* **With RVM**
First you have to install `curl` (e.g. `sudo apt install curl` on Debian-based systems).
And then:
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):
```bash

<summary>
### WSL
</summary>
On WSL we can't use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
<h2 id="creating-a-new-user-and-setting-up-the-database">3.2. Creating a new user and setting up the database</h2>
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;

MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create

Created database 'qpixel_dev'
Created database 'qpixel_test'
:~/qpixel$ rails db:schema:load

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise the `Rails.cache.clear` command will fail):
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):

</details>
After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>

Now comes the big moment: You can start the QPixel server for the first time with ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise your browser will display an error message):

</details>
Open a web browser and visit your server, which should be running under http://localhost:3000.
Click on "Sign Up" button on top right corner.
Choose a email, username and password for your new administrator account.
Since the email confirmation is not configured yet, you will have to manually confirm the new user account and promote it to administrator. For that you will have to stop the current execution of the server. So, return to the console and type Ctrl-C to stop it.

</details>
Now run again the `rails s` command, return to the web browser at http://localhost:3000 and this time you "Sign in" (click on "Sign In" button on top right corner) with your new admin user account.
<h1 id="new-site-setup">5. New site setup</h1>
There's one more thing before your development server is fully up and running: the new site setup.
While being logged into your administrator account, go to http://localhost:3000/admin/setup. Review the settings (if you want; you can change them later) and click "Save and continue" to complete setting up the dev server.
✨ Your dev server is now ready.
<h1 id="running-the-server-in-production">6. Running the server in production</h1>
If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).
~~***Credit:** this post is was initially written by luap42 in [this answer](https://collab.codidact.org/posts/280451/280452#answer-280452).*~~
[^1]: It seems that the rails console can't run on WSL1 (but no problem with WSL2). Also, note that the install is significantly faster with WSL2.

This post aims to provide a step-by-step tutorial regarding the installation/operation of Codidact/QPixel server locally (development mode) or on a network (in production mode).

QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>
<summary>
### Unix-based
</summary>
* **With RVM**
First you have to install `curl` (e.g. `sudo apt install curl` on Debian-based systems).
And then:
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):

If the database is not already running, start it. This step depends strongly on the OS/platform used and the database server used (e.g. MySQL or MariaDB).

### WSL
</summary>
On WSL we can't use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
<h2 id="creating-a-new-user-and-setting-up-the-database">3.2. Creating a new user and setting up the database</h2>
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_test.* TO qpixel@localhost;

MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create
Running via Spring preloader in process 26070
Created database 'qpixel_dev'
Created database 'qpixel_test'
:~/qpixel$ rails db:schema:load

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise the `Rails.cache.clear` command will fail):
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

```
</details>
After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

Now comes the big moment: You can start the QPixel server for the first time with ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise your browser will display an error message):
<details>

</details>
Open a web browser and visit your server, which should be running under http://localhost:3000.
Click on "Sign Up" button on top right corner.
Choose a email, username and password for your new administrator account.
Since the email confirmation is not configured yet, you will have to manually confirm the new user account and promote it to administrator. For that you will have to stop the current execution of the server. So, return to the console and type Ctrl-C to stop it.

<summary>
```ruby
User.last.update(confirmed_at: DateTime.now, is_global_admin: true)

```
</summary>

</details>
Now run again the `rails s` command, return to the web browser at http://localhost:3000 and this time you "Sign in" (click on "Sign In" button on top right corner) with your new admin user account.
<h1 id="new-site-setup">5. New site setup</h1>
There's one more thing before your development server is fully up and running: the new site setup.
While being logged into your administrator account, go to http://localhost:3000/admin/setup. Review the settings (if you want; you can change them later) and click "Save and continue" to complete setting up the dev server.
✨ Your dev server is now ready.
<h1 id="running-the-server-in-production">6. Running the server in production</h1>
If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).
***Credit:** this post was initially written by luap42 in [this answer](https://collab.codidact.org/posts/280451/280452#answer-280452).*
[^1]: It seems that the rails console can't run on WSL1 (but no problem with WSL2). Also, note that the install is significantly faster with WSL2.

To run your own instance of QPixel you'll need at least:
* A Linux or Mac computer (Windows Subsystem Linux, WLS[^1] is also okay, but slower; running Ruby on Windows is ultra-slow)
* Some prerequisites (including Ruby and database server install) which can differ depending on the OS or platform used (e.g. WLS).

QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>
<summary>
### Unix-based
</summary>
* **With RVM**
First you have to install `curl` (e.g. `sudo apt install curl` on Debian-based systems).
And then:
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):
```bash
~$ curl -sSL https://get.rvm.io | bash -s stable

On WSL we can't use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
<h2 id="creating-a-new-user-and-setting-up-the-database">3.2. Creating a new user and setting up the database</h2>
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```

Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate

```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise the `Rails.cache.clear` command will fail):
<details>
<summary>
```ruby

Rails.cache.clear
exit
```
</summary>

After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>

<h1 id="running-the-server-in-production">6. Running the server in production</h1>
If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).
***Credit:** this post is was initially written by luap42 in [this answer](https://collab.codidact.org/posts/280451/280452#answer-280452).*
[^1]: It seems that the rails console can't run on WSL1 (but no problem with WSL2). Also, note that the install is significantly faster with WSL2.

This post aims to provide a step-by-step tutorial regarding the installation/operation of Codidact/QPixel server locally (development mode) or on a network (in production mode).

<h2 id="ruby-install">1.3. Ruby install</h2>
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>
<summary>
### Unix-based
</summary>
* **With RVM**
First you have to install `curl` (e.g. `sudo apt install curl` on Debian-based systems).
And then:
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):
```bash
~$ curl -sSL https://get.rvm.io | bash -s stable

### WSL
</summary>
On WSL we can't use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
<h2 id="creating-a-new-user-and-setting-up-the-database">3.2. Creating a new user and setting up the database</h2>
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33

MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):

```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise the `Rails.cache.clear` command will fail):

If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).
***Credit:** this post is was initially written by luap42 in [this answer](https://collab.codidact.org/posts/280451/280452#answer-280452).*
[^1]: It seems that the rails console can't run on WSL1 (but no problem with WSL2). Also, note that the install is significantly faster with WSL2.

To run your own instance of QPixel you'll need at least:
* A Linux or Mac computer (Windows Subsystem Linux, WLS[^1] is also okay, but slower; running Ruby on Windows is ultra-slow)
* Some prerequisites (including Ruby and database server install) which can differ depending on the OS or platform used (e.g. WLS).

* **On Debian:**
MySQL is not available on the Debian default distribution, thus MariaDB can be installed instead:
```bash
sudo apt install mariadb-server
```
If you really want to install MySQL on Debian, you can take a look at [this discussion](https://linux.codidact.com/posts/288849), [this answer regarding Dockerized instance of MySQL on WSL or directly on the Windows Host](https://linux.codidact.com/posts/288812/288970#answer-288970) and [this official workflow](https://dev.mysql.com/doc/mysql-installation-excerpt/8.0/en/linux-installation-debian.html)).

<h2 id="ruby-install">1.3. Ruby install</h2>
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>
<summary>
### Unix-based
</summary>
* **With RVM**
First you have to install `curl` (e.g. `sudo apt install curl` on Debian-based systems).
And then:
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):
```bash
~$ curl -sSL https://get.rvm.io | bash -s stable

Adding rvm loading line to /home/zetyty/.profile /home/zetyty/.bash_profile /home/zetyty/.zlogin.
Installation of RVM in /home/zetyty/.rvm/ is almost complete:
* To start using RVM you need to run `source /home/zetyty/.rvm/scripts/rvm`
in all your open shell windows, in rare cases you need to reopen all shell windows.
Thanks for installing RVM 🙏
Please consider donating to our open collective to help us maintain RVM.

Then, install ruby:
```bash
rvm install 3.1.2
```

</details>
After downloading QPixel, you need to install all the dependencies. For that, you need to move to the `qpixel` directory and run ([**without** sudo/root/admin privileges](https://collab.codidact.org/posts/288973/288996#answer-288996)):

### WSL
</summary>
On WSL we can't use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
<h2 id="creating-a-new-user-and-setting-up-the-database">3.2. Creating a new user and setting up the database</h2>
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;

MariaDB [(none)]> GRANT ALL ON qpixel_test.* TO qpixel@localhost;

MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create
Running via Spring preloader in process 26070
Created database 'qpixel_dev'
Created database 'qpixel_test'
:~/qpixel$ rails db:schema:load

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise the `Rails.cache.clear` command will fail):
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

</details>
After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>

There's one more thing before your development server is fully up and running: the new site setup.
While being logged into your administrator account, go to http://localhost:3000/admin/setup. Review the settings (if you want; you can change them later) and click "Save and continue" to complete setting up the dev server.
✨ Your dev server is now ready.

If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).
***Credit:** this post is was initially written by luap42 in [this answer](https://collab.codidact.org/posts/280451/280452#answer-280452).*
[^1]: It seems that the rails console can't run on WSL1 (but no problem with WSL2). Also, note that the install is significantly faster with WSL2.

This post aims to provide a step-by-step tutorial regarding the installation/operation of Codidact/QPixel server locally (development mode) or on a network (in production mode).

To run your own instance of QPixel you'll need at least:
* A Linux or Mac computer (Windows Subsystem Linux, WLS[^1] is also okay, but slower; running Ruby on Windows is ultra-slow)
* Some prerequisites (including Ruby and database server install) which can differ depending on the OS or platform used (e.g. WLS).

<h2 id="ruby-install">1.3. Ruby install</h2>
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>
<summary>
### Unix-based
</summary>
* **With RVM**
First you have to install `curl` (e.g. `sudo apt install curl` on Debian-based systems).
And then:
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):
```bash
~$ curl -sSL https://get.rvm.io | bash -s stable

Then, install ruby:
```bash
rvm install 3.1.2
```

Once you have completed installing the prerequisites, you can download QPixel with the following command line (*in this wiki post, a sample of the command outputs obtained on Debian is provided below each inline command to give an idea of what kind of results are expected*):
<details>
<summary>
```bash
git clone https://github.com/codidact/qpixel

</details>
After downloading QPixel, you need to install all the dependencies. For that, you need to move to the `qpixel` directory and run ([**without** sudo/root/admin privileges](https://collab.codidact.org/posts/288973/288996#answer-288996)):

</summary>
```bash

### WSL
</summary>
On WSL we can't use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
<h2 id="creating-a-new-user-and-setting-up-the-database">3.2. Creating a new user and setting up the database</h2>
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_test.* TO qpixel@localhost;

MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create
Running via Spring preloader in process 26070
Created database 'qpixel_dev'
Created database 'qpixel_test'
:~/qpixel$ rails db:schema:load

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise the `Rails.cache.clear` command will fail):
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails c

3.1.2 :002 > Rails.cache.clear
=> "OK"
3.1.2 :003 > exit
```
</details>
After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

</details>
<h1 id="creating-an-administrator-account">4. Creating an administrator account</h1>
Now comes the big moment: You can start the QPixel server for the first time with ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise your browser will display an error message):
<details>
<summary>
```bash

</details>
Open a web browser and visit your server, which should be running under http://localhost:3000.
Click on "Sign Up" button on top right corner.
Choose a email, username and password for your new administrator account.
Since the email confirmation is not configured yet, you will have to manually confirm the new user account and promote it to administrator. For that you will have to stop the current execution of the server. So, return to the console and type Ctrl-C to stop it.

</details>
Now run again the `rails s` command, return to the web browser at http://localhost:3000 and this time you "Sign in" (click on "Sign In" button on top right corner) with your new admin user account.
<h1 id="new-site-setup">5. New site setup</h1>

QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>

#### With RVM
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):

### WSL
</summary>
On WSL we can't use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
<h2 id="creating-a-new-user-and-setting-up-the-database">3.2. Creating a new user and setting up the database</h2>
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;

MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
~~Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands:~~
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

</details>
After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>

</details>
Now run again the `rails s` command, return to the web browser at http://localhost:3000 and this time you "Sign in" (click on "Sign In" button on top right corner) with your new admin user account.
<h1 id="new-site-setup">5. New site setup</h1>
There's one more thing before your development server is fully up and running: the new site setup.
While being logged into your administrator account, go to http://localhost:3000/admin/setup. Review the settings (if you want; you can change them later) and click "Save and continue" to complete setting up the dev server.
✨ Your dev server is now ready.
<h1 id="running-the-server-in-production">6. Running the server in production</h1>
If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).
~~***Credit:** this question was initially written by luap42 in [this answer](https://collab.codidact.org/posts/280451/280452#answer-280452).*~~
[^1]: It seems that the rails console can't run on WSL1 (but no problem with WSL2). Also, note that the install is significantly faster with WSL2.

This post aims to provide a step-by-step tutorial regarding the installation/operation of Codidact/QPixel server locally (development mode) or on a network (in production mode).

QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).

* **With RVM**
First you have to install `curl` (e.g. `sudo apt install curl` on Debian-based systems).
And then:
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm

<h1 id="setting-up-the-database">3. Setting up the Database</h1>

### WSL
</summary>
On WSL we can't use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
<h2 id="creating-a-new-user-and-setting-up-the-database">3.2. Creating a new user and setting up the database</h2>
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;

MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise the `Rails.cache.clear` command will fail):
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):

</details>
After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):

Now comes the big moment: You can start the QPixel server for the first time with ([make sure you have Redis already started](https://collab.codidact.org/posts/285407/285409#answer-285409) because otherwise your browser will display an error message):

Open a web browser and visit your server, which should be running under http://localhost:3000.
Click on "Sign Up" button on top right corner.
Choose a email, username and password for your new administrator account.
Since the email confirmation is not configured yet, you will have to manually confirm the new user account and promote it to administrator. For that you will have to stop the current execution of the server. So, return to the console and type Ctrl-C to stop it.

</details>
Now run again the `rails s` command, return to the web browser at http://localhost:3000 and this time you "Sign in" (click on "Sign In" button on top right corner) with your new admin user account.

There's one more thing before your development server is fully up and running: the new site setup.
While being logged into your administrator account, go to http://localhost:3000/admin/setup. Review the settings (if you want; you can change them later) and click "Save and continue" to complete setting up the dev server.
✨ Your dev server is now ready.

If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).
***Credit:** this post is was initially written by luap42 in [this answer](https://collab.codidact.org/posts/280451/280452#answer-280452).*
[^1]: It seems that the rails console can't run on WSL1 (but no problem with WSL2). Also, note that the install is significantly faster with WSL2.

To run your own instance of QPixel you'll need at least:
* A Linux or Mac computer (Windows Subsystem Linux, WLS[^1] is also okay, but slower; running Ruby on Windows is ultra-slow)
* Some prerequisites (including Ruby and database server install) which can differ depending on the OS or platform used (e.g. WLS).

QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).

#### With RVM
```bash

curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm

On WSL we can't use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
<h2 id="creating-a-new-user-and-setting-up-the-database">3.2. Creating a new user and setting up the database</h2>
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';

MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands:
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>

After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>

```
</details>
Open a web browser and visit your server, which should be running under http://localhost:3000.
Click on "Sign Up" button on top right corner.
Choose a email, username and password for your new administrator account.
Since the email confirmation is not configured yet, you will have to manually confirm the new user account and promote it to administrator. For that you will have to stop the current execution of the server. So, return to the console and type Ctrl-C to stop it.

Now run again the `rails s` command, return to the web browser at http://localhost:3000 and this time you "Sign in" (click on "Sign In" button on top right corner) with your new admin user account.
<h1 id="new-site-setup">5. New site setup</h1>
There's one more thing before your development server is fully up and running: the new site setup.
While being logged into your administrator account, go to http://localhost:3000/admin/setup. Review the settings (if you want; you can change them later) and click "Save and continue" to complete setting up the dev server.
✨ Your dev server is now ready.
<h1 id="running-the-server-in-production">6. Running the server in production</h1>
If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).
[^1]: It seems that the rails console can't run on WSL1 (but no problem with WSL2). Also, note that the install is significantly faster with WSL2.

This post aims to provide a step-by-step tutorial regarding the installation/operation of Codidact/QPixel server locally (development mode) or on a network (in production mode).
*The "official" installation guide is available on [GitHub](https://github.com/codidact/qpixel/blob/develop/INSTALLATION.md).*

To run your own instance of QPixel you'll need at least:
* A Linux or Mac computer (Windows Subsystem Linux, WLS[^1] is also okay, but slower; running Ruby on Windows is ultra-slow)
* Some prerequisites (including Ruby and database server install) which can differ depending on the OS or platform used (e.g. WLS).

MySQL is not available on the Debian default distribution, thus MariaDB can be installed instead:
```bash
sudo apt install mariadb-server
```
If you really want to install MySQL on Debian, you can take a look at [this discussion](https://linux.codidact.com/posts/288849), [this answer regarding Dockerized instance of MySQL on WSL or directly on the Windows Host](https://linux.codidact.com/posts/288812/288970#answer-288970) and [this official workflow](https://dev.mysql.com/doc/mysql-installation-excerpt/8.0/en/linux-installation-debian.html)).

<h2 id="ruby-install">1.3. Ruby install</h2>
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).

#### With RVM
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```

If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).
***Credit:** this question was initially written by luap42 in [this answer](https://collab.codidact.org/posts/280451/280452#answer-280452).*
[^1]: It seems that the rails console can't run on WSL1 (but no problem with WSL2). Also, note that the install is significantly faster with WSL2.

To run your own instance of QPixel you'll need at least:
* A Linux or Mac computer (Windows Subsystem Linux, WLS[^1] is also okay, but slower; running Ruby on Windows is ultra-slow)
* Some prerequisites (including Ruby and database server install) which can differ depending on the OS or platform used (e.g. WLS).

QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).

#### With RVM
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):

On WSL we can't use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
~~</div>~~
~~<div id="creating-a-new-user-and-setting-up-the-database">~~
~~## 3.2. Creating a new user and setting up the database~~
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_test.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create
Running via Spring preloader in process 26070
Created database 'qpixel_dev'
Created database 'qpixel_test'

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands:
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed

To run your own instance of QPixel you'll need at least:
* A Linux or Mac computer (Windows Subsystem Linux, WLS[^1] is also okay, but slower; running Ruby on Windows is ultra-slow)
* Some prerequisites (including Ruby and database server install) which can differ depending on the OS or platform used (e.g. WLS).
<h2 id="initial-prerequisites">1.1. Initial prerequisites</h2>
The command lines for installing all the initial prerequisites are listed below for different OS.

On Ubuntu:
```bash
sudo apt install mysql-server
```
MySQL is not available on the Debian default distribution, thus MariaDB can be installed instead:
```bash
sudo apt install mariadb-server
```
If you really want to install MySQL on Debian, you can take a look at [this discussion](https://linux.codidact.com/posts/288849), [this answer regarding Dockerized instance of MySQL on WSL or directly on the Windows Host](https://linux.codidact.com/posts/288812/288970#answer-288970) and [this official workflow](https://dev.mysql.com/doc/mysql-installation-excerpt/8.0/en/linux-installation-debian.html)).

</details>
<h2 id="ruby-install">1.3. Ruby install</h2>
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>

#### With RVM
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):

### WSL
</summary>
On WSL we can't use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
<h2 id="creating-a-new-user-and-setting-up-the-database">3.2. Creating a new user and setting up the database</h2>
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_test.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create
Running via Spring preloader in process 26070
Created database 'qpixel_dev'
Created database 'qpixel_test'
:~/qpixel$ rails db:schema:load
Running via Spring preloader in process 26094
:~/qpixel$ rails r db/scripts/create_tags_path_view.rb
Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands:
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails c
Running via Spring preloader in process 26118
Loading development environment (Rails 7.0.4)
3.1.2 :001 > Community.create(name: 'Dev Community', host: 'localhost:3000')
Community Exists? (0.6ms) SELECT 1 AS one FROM `communities` WHERE `communities`.`host` = 'localhost:3000' LIMIT 1
Community Create (0.4ms) INSERT INTO `communities` (`name`, `host`, `created_at`, `updated_at`, `is_fake`, `hidden`) VALUES ('Dev Community', 'localhost:3000', '2023-07-14 19:19:04', '2023-07-14 19:19:04', FALSE, FALSE)

is_fake: false,
hidden: false>
3.1.2 :002 > Rails.cache.clear
=> "OK"
3.1.2 :003 > exit
```
</details>
After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:seed

</details>
<h1 id="creating-an-administrator-account">4. Creating an administrator account</h1>
Now comes the big moment: You can start the QPixel server for the first time with ([be sure to have `redis-server` already started](https://collab.codidact.org/posts/285407/285409#answer-285409)):
<details>
<summary>
```bash
rails s
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails s

```
</details>
Open a web browser and visit your server, which should be running under http://localhost:3000.
Click on "Sign Up" button on top right corner.
Choose a email, username and password for your new administrator account.
Since the email confirmation is not configured yet, you will have to manually confirm the new user account and promote it to administrator. For that you will have to stop the current execution of the server. So, return to the console and type Ctrl-C to stop it.

</details>
Open the rails console with `rails c` and run:
<details>
<summary>
```ruby
User.last.update(confirmed_at: DateTime.now, is_global_admin: true)
exit
```
</summary>

TRANSACTION (3.8ms) COMMIT
=> true
3.1.2 :002 > exit
```
</details>
Now run again the `rails s` command, return to the web browser at http://localhost:3000 and this time you "Sign in" (click on "Sign In" button on top right corner) with your new admin user account.
<h1 id="new-site-setup">5. New site setup</h1>
There's one more thing before your development server is fully up and running: the new site setup.
While being logged into your administrator account, go to http://localhost:3000/admin/setup. Review the settings (if you want; you can change them later) and click "Save and continue" to complete setting up the dev server.
✨ Your dev server is now ready.
<h1 id="running-the-server-in-production">6. Running the server in production</h1>
If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).

QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).

On WSL we can't use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
</div>
~~<div id="create-a-new-user-and-setting-up-the-database">~~
## 3.2. Creating a new user and setting up the database
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_test.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create
Running via Spring preloader in process 26070
Created database 'qpixel_dev'
Created database 'qpixel_test'

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands:
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

=> "OK"

```
</details>
After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>

On WSL we can't use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
</div>
<div id="creating-a-new-user-and-setting-up-the-database">
## 3.2. Creating a new user and setting up the database
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_test.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands:
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

```
</details>
After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>

Open a web browser and visit your server, which should be running under http://localhost:3000.
Click on "Sign Up" button on top right corner.
Choose a email, username and password for your new administrator account.
Since the email confirmation is not configured yet, you will have to manually confirm the new user account and promote it to administrator. For that you will have to stop the current execution of the server. So, return to the console and type Ctrl-C to stop it.

# 1. Prerequisites
To run your own instance of QPixel you'll need at least:
* A Linux or Mac computer (Windows Subsystem Linux, WLS[^1] is also okay, but slower; running Ruby on Windows is ultra-slow)
* Some prerequisites (including Ruby and database server install) which can differ depending on the OS or platform used (e.g. WLS).

## 1.3. Ruby install
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>

#### With RVM
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):

Adding rvm loading line to /home/zetyty/.profile /home/zetyty/.bash_profile /home/zetyty/.zlogin.
Installation of RVM in /home/zetyty/.rvm/ is almost complete:
* To start using RVM you need to run `source /home/zetyty/.rvm/scripts/rvm`
in all your open shell windows, in rare cases you need to reopen all shell windows.
Thanks for installing RVM 🙏

Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash

Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands:

<summary>
```ruby

# 1. Prerequisites
To run your own instance of QPixel you'll need at least:
* A Linux or Mac computer (Windows Subsystem Linux, WLS[^1] is also okay, but slower; running Ruby on Windows is ultra-slow)
* Some prerequisites (including Ruby and database server install) which can differ depending on the OS or platform used (e.g. WLS).

## 1.3. Ruby install
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>

#### With RVM
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):

</details>
</div>
<div id="create-a-new-user-and-setting-up-the-database">
## 3.2. Creating a new user and setting up the database
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_test.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>

Open a web browser and visit your server, which should be running under http://localhost:3000.
Click on "Sign Up" button on top right corner.
Choose a email, username and password for your new administrator account.
Since the email confirmation is not configured yet, you will have to manually confirm the new user account and promote it to administrator. For that you will have to stop the current execution of the server. So, return to the console and type Ctrl-C to stop it.

<div id="prerequisites">
# 1. Prerequisites
To run your own instance of QPixel you'll need at least:
* A Linux or Mac computer (Windows Subsystem Linux, WLS[^1] is also okay, but slower; running Ruby on Windows is ultra-slow)
* Some prerequisites (including Ruby and database server install) which can differ depending on the OS or platform used (e.g. WLS).
<div id="initial-prerequisites">
## 1.1. Initial prerequisites.
The command lines for installing all the initial prerequisites are listed below for different OS.
<details>

</details>
<details>
<summary>
### Debian-based
</summary>
MySQL is not available on the Debian default distribution, thus MariaDB can be installed instead:
```bash
sudo apt install mariadb-server
```
If you really want to install MySQL on Debian, you can take a look at [this discussion](https://linux.codidact.com/posts/288849), [this answer regarding Dockerized instance of MySQL on WSL or directly on the Windows Host](https://linux.codidact.com/posts/288812/288970#answer-288970) and [this official workflow](https://dev.mysql.com/doc/mysql-installation-excerpt/8.0/en/linux-installation-debian.html)).

<summary>
### Fedora
</summary>
```bash
dnf install community-mysql-server
```
</details>
</div>
<div id="ruby-install">
## 1.3. Ruby install
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>

#### With RVM
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):

## 3.1. Starting the database server
If the database is not already running, start it. This step depends strongly on the OS/platform used and the database server used (e.g. MySQL or MariaDB).

</summary>
On WSL we can't use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
</div>
<div id="create-a-new-user-and-setting-up-the-database">
## 3.2. Creating a new user and setting up the database
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_test.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. With MariaDB**, "you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb`" (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
~~Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):~~
```bash
:~/qpixel$ rails db:create
Running via Spring preloader in process 26070
Created database 'qpixel_dev'
Created database 'qpixel_test'
:~/qpixel$ rails db:schema:load

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands:
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
~~Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):~~
```bash

```
</details>
After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>

MySQL is not available on the Debian default distribution, thus MariaDB can be installed instead:
```bash
sudo apt install mariadb-server
```
If you really want to install MySQL on Debian, you can take a look at [this discussion](https://linux.codidact.com/posts/288849), [this answer regarding Dockerized instance of MySQL on WSL or directly on the Windows Host](https://linux.codidact.com/posts/288812/288970#answer-288970) and [this official workflow](https://dev.mysql.com/doc/mysql-installation-excerpt/8.0/en/linux-installation-debian.html)).

## 1.3. Ruby install
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).

#### With RVM
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):

## 3.1. Starting the database server
If the database is not already running, start it. This step depends strongly on the OS/platform used and the database server used (e.g. MySQL or MariaDB).
<details>
<summary>
### MacOS
</summary>
```bash
brew services start mysql
```

### WSL
</summary>
On WSL we can't use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL).
</details>
</div>
<div id="create-a-new-user-and-setting-up-the-database">
## 3.2. Creating a new user and setting up the database
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_test.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. with MariaDB**, you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb` (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create
Running via Spring preloader in process 26070
Created database 'qpixel_dev'
Created database 'qpixel_test'
:~/qpixel$ rails db:schema:load

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands:
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails c

=> "OK"
3.1.2 :003 > exit
```
</details>
After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>

# 3. Setting up the Database
~~## 3.1. Start the database server~~
If the database is not already running, start it. This step depends strongly on the OS/platform used and the database server used (e.g. MySQL or MariaDB).
**Table 2** below gives some command line exemple to start your database server depending on the OS.
~~<table>~~
~~<tr>~~
~~<td> OS </td> <td> MySQL </td> <td> MariaDB </td>~~
~~</tr>~~
<tr>
~~<td> MacOS </td>~~
<td>
```bash
brew services start mysql
```
~~</td>~~
<td> </td>
~~</tr>~~
~~<tr>~~
<td> Debian-based </td>
~~<td>~~

<td>
```bash
sudo systemctl start mariadb
```
or
```bash
sudo service mariadb start
```
~~</td>~~
</tr>
~~<tr>~~
<td> Fedora </td>
~~<td>~~
```bash
systemctl enable mysqld
systemctl start mysqld
```
</td>
~~<td>~~
~~</td>~~
~~</tr>~~
</table>
**N.B. On WSL** we can't use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL)[^3].
~~## 3.2. Create a new user and set up the database~~
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_test.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. With MariaDB**, "you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb`" (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create
Running via Spring preloader in process 26070
Created database 'qpixel_dev'
Created database 'qpixel_test'

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands:
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash

After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>

~~[^1]: It seems taht the rails console can't run on WSL1 (but I got no problem with WSL2). Also, note that the install is significantly faster with WSL2.~~
[^2]: If you really want to install MySQL, you can take a look at [this discussion](https://linux.codidact.com/posts/288849), [this answer regarding Dockerized instance of MySQL on WSL or directly on the Windows Host](https://linux.codidact.com/posts/288812/288970#answer-288970) and [this official workflow](https://dev.mysql.com/doc/mysql-installation-excerpt/8.0/en/linux-installation-debian.html)).
[^3]: To stop MySQL on Windows: ppen a on command prompt and run `net stop MySQL80`. On other running WSL, (i) you can stop MySQL/MariaDB server on other WSL or (ii) you can stop the running WSL by opening a PowerShell and run `wsl -t DISTRO-NAME` - you can find the list of all `DISTRO-NAME` installed and their status (running/stopped) with `wsl -l -v`.

# 1. Prerequisites
To run your own instance of QPixel you'll need at least:
* A Linux or Mac computer (Windows Subsystem Linux, WLS[^1] is also okay, but slower; running Ruby on Windows is ultra-slow)
* Some prerequisites (including Ruby and database server install) which can differ depending on the OS or platform used (e.g. WLS).

## 1.3. Ruby install
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend a Ruby `gem` manager like [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
N.B. QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).

curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm

## 3.2. Creating a new user and setting up the database
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_test.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. With MariaDB**, "you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb`" (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash

</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands:
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>

After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>

```bash
rails db:seed

Open a web browser and visit your server, which should be running under http://localhost:3000.
Click on "Sign Up" button on top right corner.
Choose a email, username and password for your new administrator account.
Since the email confirmation is not configured yet, you will have to manually confirm the new user account and promote it to administrator. For that you will have to stop the current execution of the server. So, return to the console and type Ctrl-C to stop it.

To run your own instance of QPixel you'll need at least:
* A Linux or Mac computer (Windows WSL2 is also okay, but slower; running Ruby on Windows is ultra-slow)
Also you'll need some prerequisites (including Ruby and database server install) which can differ depending on the OS or platform used (ex. Windows Subsystem Linux, WLS).

QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>
<summary>
Example with RVM on Debian:
</summary>
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):
```bash
~$ curl -sSL https://get.rvm.io | bash -s stable

Adding rvm loading line to /home/zetyty/.profile /home/zetyty/.bash_profile /home/zetyty/.zlogin.
Installation of RVM in /home/zetyty/.rvm/ is almost complete:
* To start using RVM you need to run `source /home/zetyty/.rvm/scripts/rvm`
in all your open shell windows, in rare cases you need to reopen all shell windows.
Thanks for installing RVM 🙏
Please consider donating to our open collective to help us maintain RVM.

Then, install ruby:
```bash
rvm install 3.1.2

**N.B. On WSL** we can't use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL)[^3].
## 3.2. Create a new user and set up the database
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;

</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):

```
**N.B. With MariaDB**, "you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb`" (4 occurrences).
Now we want to create the database and the tables with:

[^1]: It seems taht the rails console can't run on WSL1 (but I got no problem with WSL2). Also, note that the install is significantly faster with WSL2.
[^2]: If you really want to install MySQL, you can take a look at [this discussion](https://linux.codidact.com/posts/288849), [this answer regarding Dockerized instance of MySQL on WSL or directly on the Windows Host](https://linux.codidact.com/posts/288812/288970#answer-288970) and [this official workflow](https://dev.mysql.com/doc/mysql-installation-excerpt/8.0/en/linux-installation-debian.html)).
[^3]: To stop MySQL on Windows: ppen a on command prompt and run `net stop MySQL80`. On other running WSL, (i) you can stop MySQL/MariaDB server on other WSL or (ii) you can stop the running WSL by opening a PowerShell and run `wsl -t DISTRO-NAME` - you can find the list of all `DISTRO-NAME` installed and their status (running/stopped) with `wsl -l -v`.

## 1.3. Ruby install
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>
<summary>
Example with RVM on Debian:
</summary>
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):
```bash
~$ curl -sSL https://get.rvm.io | bash -s stable

Adding rvm loading line to /home/zetyty/.profile /home/zetyty/.bash_profile /home/zetyty/.zlogin.
Installation of RVM in /home/zetyty/.rvm/ is almost complete:
* To start using RVM you need to run `source /home/zetyty/.rvm/scripts/rvm`
in all your open shell windows, in rare cases you need to reopen all shell windows.
Thanks for installing RVM 🙏

# 3. Setting up the Database
## 3.1. Start the database server
If the database is not already running, start it. This step depends strongly on the OS/platform used and the database server used (e.g. MySQL or MariaDB).

**N.B. On WSL** we can't use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL)[^3].
## 3.2. Create a new user and set up the database
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_test.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. With MariaDB**, "you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb`" (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create
Running via Spring preloader in process 26070
Created database 'qpixel_dev'
Created database 'qpixel_test'

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands:
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash

After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed

If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).
</div>
[^1]: It seems taht the rails console can't run on WSL1 (but I got no problem with WSL2). Also, note that the install is significantly faster with WSL2.
[^2]: If you really want to install MySQL, you can take a look at [this discussion](https://linux.codidact.com/posts/288849), [this answer regarding Dockerized instance of MySQL on WSL or directly on the Windows Host](https://linux.codidact.com/posts/288812/288970#answer-288970) and [this official workflow](https://dev.mysql.com/doc/mysql-installation-excerpt/8.0/en/linux-installation-debian.html)).
[^3]: To stop MySQL on Windows: ppen a on command prompt and run `net stop MySQL80`. On other running WSL, (i) you can stop MySQL/MariaDB server on other WSL or (ii) you can stop the running WSL by opening a PowerShell and run `wsl -t DISTRO-NAME` - you can find the list of all `DISTRO-NAME` installed and their status (running/stopped) with `wsl -l -v`.

# 3. Setting up the Database
## 3.1. Start the database server
If the database is not already running, start it. This step depends strongly on the OS/platform used and the database server used (e.g. MySQL or MariaDB).
**Table 2** below gives some links to posts where you could find how to start your database server.
~~|OS|Database|Link|~~
~~|-|-|-|~~
~~|Unix-based| MySQL |[**Unix-based answer** of "How to set up a new (development) instance of Codidact/QPixel"](https://collab.codidact.org/posts/280451/280452#answer-280452)|~~

## 3.2. Create a new user and set up the database
~~Sign into the MySQL/MariaDB console with for e.g.:~~
```bash
sudo mysql -u root
```
~~And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword"):~~
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_test.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Now copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are:
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**With MariaDB**, "you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb`" (4 occurrences).
~~Create the rails database with:~~
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):

</details>
Create a (first) community by opening the rails console with `rails c` and running these commands:
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>

<summary>
```bash
rails db:seed

## 1.3. Ruby install
QPixel is built with Ruby on Rails, therefore you'll need to install Ruby and we recommend [RVM](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv#installation).
QPixel is tested with Ruby 3 (and works with Ruby 2.7 as of December 2022).
<details>
<summary>
Example with RVM on Debian:
</summary>
```bash
curl -sSL https://rvm.io/mpapis.asc | gpg --import -
curl -sSL https://rvm.io/pkuczynski.asc | gpg --import -
curl -sSL https://get.rvm.io | bash -s stable
```
If rvm installation is complete it will tells you which command to run in order to be able to use the `rvm` command. In the installation outputs sample below, this command is (you need to run this command in each new opened terminal):
```bash
source /home/zetyty/.rvm/scripts/rvm
```
Installation outputs sample on Debian 12 (for user "zetyty"):
```bash
~$ curl -sSL https://get.rvm.io | bash -s stable

Adding rvm loading line to /home/zetyty/.profile /home/zetyty/.bash_profile /home/zetyty/.zlogin.
Installation of RVM in /home/zetyty/.rvm/ is almost complete:
* To start using RVM you need to run `source /home/zetyty/.rvm/scripts/rvm`
in all your open shell windows, in rare cases you need to reopen all shell windows.

After downloading QPixel, you need to install all the dependencies. For that, you need to move to the `qpixel` directory and run:
<details>
<summary>
```bash
bundle install
```
</summary>
Sample outputs on Debian (QPixel installed on `/home` directory):
```bash
~/qpixel$ bundle install

# 3. Setting up the Database
## 3.1. Start the database server
If the database is not already running, start it. This step depends strongly on the OS/platform used and the database server used (e.g. MySQL or MariaDB).
**Table 2** below gives some command line exemple to start your database server depending on the OS.
<table>
<tr>
<td> OS </td> <td> MySQL </td> <td> MariaDB </td>
</tr>
<tr>
<td> MacOS </td>
<td>
```bash
brew services start mysql
```
</td>
<td> </td>
</tr>
<tr>
<td> Debian-based </td>
<td>
</td>
<td>
```bash
sudo systemctl start mariadb
```
or
```bash
sudo service mariadb start
```
</td>
</tr>
<tr>
<td> Fedora </td>
<td>
```bash
systemctl enable mysqld
systemctl start mysqld
```
</td>
<td>
</td>
</tr>
</table>
**N.B. On WSL** we can't use `systemctl` but `service` instead (see [this answer](https://linux.codidact.com/posts/288812/288823#answer-288823)), it is also necessary to **stop the execution of a MySQL/MariaDB server on the Windows Host and on other running WSL** (because this prevents the server from being launched on the current WSL)[^3].
## 3.2. Create a new user and set up the database
Before we can create, set up and seed the database, we need to make sure that we have a MySQL user. Sign into the MySQL/MariaDB console with for e.g.:
```bash
sudo mysql -u root
```
And then type these lines (you can change the user name "qpixel@localhost" and password "myPassword" with secure ones):
<details>
<summary>
```sql
CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
GRANT ALL ON qpixel_test.* TO qpixel@localhost;
GRANT ALL ON qpixel.* TO qpixel@localhost;
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ sudo mysql -u root
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 33
Server version: 10.11.3-MariaDB-1 Debian 12
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_dev.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel_test.* TO qpixel@localhost;
Query OK, 0 rows affected (0.003 sec)
MariaDB [(none)]> GRANT ALL ON qpixel.* TO qpixel@localhost;
Query OK, 0 rows affected (0.002 sec)
MariaDB [(none)]> exit
Bye
```
</details>
Then you'll have to tell QPixel which credentials to use. Copy the `config/database.sample.yml` file to `config/database.yml` and fill in with the same username and password to those given above with the command `CREATE USER qpixel@localhost IDENTIFIED BY 'myPassword';`, then in this example, the username is "qpixel" and the password is "myPassword" and the first lines of `config/database.yml` are (also, you will need to set the Redis connection details there too, unless you always choose the default installation options proposed above):
```yml
default: &default
adapter: mysql2
encoding: utf8mb4
collation: utf8mb4_unicode_ci
host: 127.0.0.1
port: 3306
# Change these credentials to match your own environment
username: qpixel
password: myPassword
```
**N.B. With MariaDB**, "you will need to replace all occurrences of `utf8mb4_0900_ai_ci` with `utf8mb4_unicode_ci` in `db/schema.rb`" (4 occurrences).
Now we want to create the database and the tables with:
<details>
<summary>
```bash
rails db:create
rails db:schema:load
rails r db/scripts/create_tags_path_view.rb
rails db:migrate
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash
:~/qpixel$ rails db:create
Running via Spring preloader in process 26070
Created database 'qpixel_dev'
Created database 'qpixel_test'
:~/qpixel$ rails db:schema:load

Running via Spring preloader in process 26103
:~/qpixel$ rails db:migrate
Running via Spring preloader in process 26108
```
</details>
Before we can continue and seed the data, you'll have to create the record for your (first) community. Open the Rails console with `rails c` and run these commands:
<details>
<summary>
```ruby
Community.create(name: 'Dev Community', host: 'localhost:3000')
Rails.cache.clear
exit
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash

=> "OK"
3.1.2 :003 > exit
```
</details>
After that you can fill the database with necessary seed data, such as settings, help posts and default templates by running:
<details>
<summary>
```bash
rails db:seed
```
</summary>
Sample outputs on Debian with MariaDB (QPixel installed on `/home/qpixel` directory):
```bash

```
</details>
Open a web browser and visit your server, which should be running under http://localhost:3000.
Click on "Sign Up" button on top right corner.
Choose a email, username and password for your new administrator account.
Since the email confirmation is not configured yet, you will have to manually confirm the new user account and promote it to administrator. For that you will have to stop the current execution of the server. So, return to the console and type Ctrl-C to stop it.

# 5. New site setup
There's one more thing before your development server is fully up and running: the new site setup.
While being logged into your administrator account, go to http://localhost:3000/admin/setup. Review the settings (if you want; you can change them later) and click "Save and continue" to complete setting up the dev server.
✨ Your dev server is now ready.

# 6. Running the server in production
If you want your Codidact/Qpixel server to be running in production mode in order to be accessible on the web or on a private network then [the workflow is explained on this post: How to set up a Production environment](https://collab.codidact.org/posts/287738).

[^1]: It seems taht the rails console can't run on WSL1 (but I got no problem with WSL2). Also, note that the install is significantly faster with WSL2.
[^2]: If you really want to install MySQL, you can take a look at [this discussion](https://linux.codidact.com/posts/288849), [this answer regarding Dockerized instance of MySQL on WSL or directly on the Windows Host](https://linux.codidact.com/posts/288812/288970#answer-288970) and [this official workflow](https://dev.mysql.com/doc/mysql-installation-excerpt/8.0/en/linux-installation-debian.html)).
[^3]: To stop MySQL on Windows: ppen a on command prompt and run `net stop MySQL80`. On other running WSL, (i) you can stop MySQL/MariaDB server on other WSL or (ii) you can stop the running WSL by opening a PowerShell and run `wsl -t DISTRO-NAME` - you can find the list of all `DISTRO-NAME` installed and their status (running/stopped) with `wsl -l -v`.
