Steps to Install Moodle on NixOS Latest

Step 1 - Install Required Packages

Before installing Moodle, we need to install some required packages that are needed to run the application. Run the following command to install necessary packages.

sudo nix-env -iA nixos.nginx php php-fpm mariadb

Step 2 - Install Moodle

First, you need to create a directory to install Moodle. Run the following command to create a new directory named "moodle".
```
sudo mkdir /var/www/moodle
```
Download the latest stable version of Moodle from the official website using the following command.
```
sudo curl -o /var/www/moodle/moodle.tar.gz -L https://download.moodle.org/download.php/direct/stable310/moodle-latest-310.tgz
```
Replace the version number with the latest stable release number.

Extract the downloaded package using the following command.

sudo tar xzf /var/www/moodle/moodle.tar.gz -C /var/www/moodle/

Rename the extracted directory to "moodle".

sudo mv /var/www/moodle/moodle-* /var/www/moodle/moodle

Change the ownership of the Moodle directory to the nginx user.
```
sudo chown -R nginx:nginx /var/www/moodle/moodle
```

Step 3 - Configure Nginx

To configure Nginx, create a new file for Moodle virtual host.
```
sudo nano /etc/nginx/conf.d/moodle.conf
```

Add the following content to the file.

server {
    listen 80;
    server_name example.com;

    root /var/www/moodle/moodle;

    index index.php;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ \.php$ {
        fastcgi_pass unix:/var/run/php-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

Replace "example.com" with your domain name or IP address.

Verify that the configuration file is valid with the following command.
```
sudo nginx -t
```
If the configuration file is valid, restart the Nginx service.
```
sudo systemctl restart nginx
```

Step 4 - Configure MariaDB

To configure MariaDB, start the service.
```
sudo systemctl start mariadb
```

Create a new database for Moodle.

mariadb -u root -p
MariaDB [(none)]> CREATE DATABASE moodle;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON moodle.* TO 'moodleuser'@'localhost' IDENTIFIED BY 'moodlepassword';
MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> exit;

Replace the "moodleuser" and "moodlepassword" with your desired username and password.

Open the Moodle configuration file.

sudo nano /var/www/moodle/moodle/config.php

Change the following settings to match the MariaDB database settings.

$CFG->dbtype = 'mysqli';
$CFG->dbhost = 'localhost';
$CFG->dbname = 'moodle';
$CFG->dbuser = 'moodleuser';
$CFG->dbpass = 'moodlepassword';
$CFG->prefix = 'mdl_';

Replace the "moodleuser" and "moodlepassword" with your desired username and password.

Step 5 - Open Moodle Installation Page

Open a web browser and navigate to your domain name or IP address.
```
http://example.com
```
Replace "example.com" with your domain name or IP address.
Follow the instructions to complete the Moodle installation process.
