Server Prerequisites for Moodle on Debian 12

To ensure a smooth and efficient Moodle deployment on your Debian 12 server, adherence to specific system requirements is paramount. Moodle, being a web-based application, relies on a robust web server, a reliable database, and the PHP scripting language.

Operating System: Debian 12 (Bookworm) is our chosen platform, known for its stability, security, and extensive package repository.
Web Server: We will be utilizing the Apache HTTP Server or Nginx, both highly capable web servers. For this guide, we will focus on Apache, a common and well-supported choice for Moodle deployments.
Database Server: MariaDB or MySQL is required. MariaDB is a community-developed fork of MySQL, and it is our preferred choice due to its performance and compatibility.
PHP: Moodle requires a specific version of PHP with certain extensions enabled. We will ensure the correct PHP version and its necessary modules are installed and configured.
Memory (RAM): A minimum of 1GB of RAM is recommended for basic installations, but 2GB or more is highly advisable for larger deployments or heavy user loads to ensure optimal performance.
Disk Space: Sufficient disk space is needed for the Moodle application files, database, and user uploads. We recommend at least 10GB of free space, with additional space contingent on the volume of course content and user data.
Network Connectivity: Stable internet access is necessary for downloading packages and for users to access the Moodle instance.

Preparing Your Debian 12 Server Environment

A meticulously prepared server environment is the bedrock of a successful Moodle installation. This phase involves updating your system, installing essential packages, and configuring the web server and database.

Updating the System and Installing Essential Packages

The first and most crucial step is to ensure your Debian 12 system is up-to-date. This guarantees you have the latest security patches and software versions.

Update Package Lists: Open your terminal and execute the following commands to refresh your package lists:
```
sudo apt update
sudo apt upgrade -y
```
The apt update command downloads the package information from all configured sources. apt upgrade then installs the newest versions of all packages currently installed on the system. The -y flag automatically confirms any prompts, which is useful for scripting or unattended upgrades.
Install Web Server (Apache2): We will install Apache2, a widely used and robust web server.
```
sudo apt install apache2 -y
```
After installation, Apache2 should start automatically. You can verify its status using:
```
sudo systemctl status apache2
```
You can test your Apache installation by opening a web browser and navigating to your server’s IP address or domain name. You should see the default Debian Apache page.
Install Database Server (MariaDB): MariaDB is our chosen database system for Moodle.
```
sudo apt install mariadb-server mariadb-client -y
```
Once installed, it’s crucial to secure your MariaDB installation. Run the security script:
```
sudo mysql_secure_installation
```
This script will guide you through setting a root password, removing anonymous users, disallowing remote root login, and removing the test database. It’s a vital step for hardening your database server.
Install PHP and Required Extensions: Moodle relies heavily on PHP. Debian 12 comes with PHP 8.2 by default, which is suitable for recent Moodle versions. We need to install PHP along with several essential extensions that Moodle requires for its various functionalities.
```
sudo apt install php libapache2-mod-php php-mysql php-curl php-gd php-xmlrpc php-intl php-zip php-soap php-mbstring php-ldap php-bcmath php-xml php-imagick -y
```
Let’s break down these essential PHP extensions:
- php: Installs the core PHP package.
- libapache2-mod-php: Integrates PHP with the Apache web server.
- php-mysql: Enables PHP to communicate with MySQL/MariaDB databases.
- php-curl: Provides support for the Client URL library (libcurl), used for transferring data with URLs.
- php-gd: Essential for image manipulation tasks, such as creating thumbnails or processing images within Moodle.
- php-xmlrpc: Supports the XML-RPC protocol, used for remote procedure calls, which Moodle might use for certain integrations.
- php-intl: Provides internationalization functions, crucial for Moodle’s multilingual capabilities.
- php-zip: Enables PHP to work with ZIP archives, used for packaging and unpacking course materials or plugins.
- php-soap: Supports the Simple Object Access Protocol, used for web services communication.
- php-mbstring: Provides multibyte string functions, necessary for handling various character sets and languages.
- php-ldap: Facilitates communication with LDAP servers for user authentication and directory services.
- php-bcmath: Offers arbitrary precision mathematics functions, useful for complex calculations.
- php-xml: Provides XML parsing capabilities.
- php-imagick: An alternative and often more powerful image manipulation library, utilizing ImageMagick.
After installing PHP and its extensions, you need to restart Apache for the changes to take effect:
```
sudo systemctl restart apache2
```
You can verify your PHP installation and enabled extensions by creating a PHP info file:
```
echo "<?php phpinfo(); ?>" | sudo tee /var/www/html/info.php
```
Then, access http://your_server_ip/info.php in your web browser. Ensure all the listed extensions are present and enabled. Remember to remove this file after verification for security reasons: sudo rm /var/www/html/info.php.

Configuring Apache for Moodle

While Apache’s default configuration often works, fine-tuning it for Moodle can improve performance and reliability. We’ll create a virtual host configuration specifically for Moodle.

Create Moodle Directory: It’s good practice to keep your web applications organized. Let’s create a directory for Moodle.
```
sudo mkdir /var/www/moodle
```
Configure Apache Virtual Host: Create a new Apache configuration file for Moodle.
```
sudo nano /etc/apache2/sites-available/moodle.conf
```
Paste the following configuration into the file, replacing your_domain.com with your actual domain name or your_server_ip if you’re not using a domain name.
```
<VirtualHost *:80>
    ServerAdmin webmaster@localhost
    ServerName your_domain.com
    DocumentRoot /var/www/moodle

    <Directory /var/www/moodle>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/moodle-error.log
    CustomLog ${APACHE_LOG_DIR}/moodle-access.log combined
</VirtualHost>
```
- ServerName: Specifies the domain name that Apache should use to identify this virtual host.
- DocumentRoot: Sets the directory where Moodle’s files will be located.
- <Directory> block: Configures permissions and options for the Moodle directory. AllowOverride All is crucial for Moodle’s .htaccess files to function correctly.
Enable the Virtual Host and Required Modules: Now, enable your new Moodle virtual host and essential Apache modules:
```
sudo a2ensite moodle.conf
sudo a2enmod rewrite
sudo a2dissite 000-default.conf # Disable the default site if you're using a domain
sudo systemctl reload apache2
```
- a2ensite moodle.conf: Enables the Moodle virtual host configuration.
- a2enmod rewrite: Enables the Apache rewrite module, which Moodle uses for URL rewriting.
- a2dissite 000-default.conf: Disables the default Apache welcome page, preventing conflicts if you’re using a specific domain for Moodle.
- systemctl reload apache2: Reloads Apache to apply the new configurations.

Downloading and Installing Moodle

With the server environment meticulously prepared, we can now proceed with downloading and installing the Moodle core files.

Downloading the Latest Moodle Release

It’s always best to use the latest stable release of Moodle for security and feature updates. You can find the latest version on the official Moodle website or use wget to download it directly.

Navigate to the Moodle Directory: Change your current directory to the Moodle document root we created earlier.
```
cd /var/www/
```
Download Moodle: You can find the download URL on the Moodle releases page. As of writing, the latest stable version is Moodle 4.x. Let’s assume you want to download Moodle 4.1.
```
sudo wget https://download.moodle.org/stablerelease/latest/moodle-latest.tgz
```
If you know the exact version, you can specify it:
```
sudo wget https://download.moodle.org/download.php/direct/moodle-4.1.10.tgz
```
Extract Moodle Files: Extract the downloaded archive into the /var/www/ directory.
```
sudo tar -zxvf moodle-latest.tgz
```
This will create a directory named moodle containing all Moodle core files.
Move Moodle Files to Document Root: If you downloaded moodle-latest.tgz and extracted it, you’ll have a moodle directory. If your DocumentRoot in Apache is /var/www/moodle, you need to move the contents of the extracted moodle directory there. However, if you extracted directly into /var/www/ and your DocumentRoot is /var/www/moodle, you’ll need to move the extracted moodle folder’s contents into the /var/www/moodle directory, or adjust your DocumentRoot. A cleaner approach is to move the extracted moodle directory to your intended DocumentRoot.
```
sudo mv moodle /var/www/moodle
```
If you downloaded a specific version like moodle-4.1.10.tgz, the extraction might create a moodle folder directly. Ensure that /var/www/moodle contains the Moodle files.
Set Permissions: Proper file permissions are crucial for Moodle to function correctly and securely.
```
sudo chown -R www-data:www-data /var/www/moodle
sudo chmod -R 755 /var/www/moodle
```
- chown -R www-data:www-data /var/www/moodle: Changes the owner and group of the Moodle directory and its contents to www-data, the user Apache runs as.
- chmod -R 755 /var/www/moodle: Sets read, write, and execute permissions for the owner, and read and execute permissions for the group and others.

Creating the Moodle Data Directory

Moodle stores user data, course files, and other important information in a separate directory outside the web root for security.

Create the Data Directory: It’s recommended to place this directory one level above your web root.
```
sudo mkdir /var/moodle_data
```
Set Permissions for the Data Directory: Again, ensure the www-data user has the correct permissions.
```
sudo chown -R www-data:www-data /var/moodle_data
sudo chmod -R 755 /var/moodle_data
```

Configuring the Moodle Database

Moodle requires a database to store all its information, including user accounts, course content, grades, and settings. We will create a dedicated database and a user for Moodle.

Creating a Moodle Database and User

Login to MariaDB: Access the MariaDB command-line interface as the root user.
```
sudo mysql -u root -p
```
Enter your MariaDB root password when prompted.
Create the Moodle Database: Choose a descriptive name for your Moodle database, for instance, moodle_db.
```
CREATE DATABASE moodle_db DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
```
- DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci: This ensures Moodle can handle a wide range of characters, including emojis and special characters from different languages.
Create a Moodle Database User: Create a dedicated user for Moodle with a strong password. Replace 'your_strong_password' with a secure password.
```
CREATE USER 'moodle_user'@'localhost' IDENTIFIED BY 'your_strong_password';
```
Grant Privileges to the Moodle User: Grant all necessary privileges to the moodle_user on the moodle_db database.
```
GRANT ALL PRIVILEGES ON moodle_db.* TO 'moodle_user'@'localhost';
```
Flush Privileges and Exit: Apply the privilege changes and exit the MariaDB prompt.
```
FLUSH PRIVILEGES;
EXIT;
```

The Moodle Installation Wizard

After preparing the server and database, the final step is to run the Moodle web-based installation wizard.

Accessing the Moodle Installation Page

Open Your Web Browser: Navigate to your server’s IP address or domain name in your web browser:
