How to Install Moodle LMS on Debian 12 Server

Are you looking to take full control of your online learning environment? Self-hosting a Learning Management System (LMS) like Moodle offers unparalleled flexibility, data sovereignty, and customization. This comprehensive guide will walk tech-savvy readers through the complete installation of Moodle on a Debian 12 server, leveraging the robust LAMP stack. You’ll learn to set up your server, enhance server security with UFW and Certbot, and configure Moodle for optimal performance, ensuring a powerful and private educational platform.

Getting Started: Prerequisites & Core Dependencies

System Requirements

Before diving into your Moodle self-hosting journey, ensure your Debian 12 server meets these fundamental requirements:

• A Debian 12 server instance.
• A non-root user with administrator (sudo) privileges.
• A domain name properly pointed to your server’s IP address.

Installing the LAMP Stack

Moodle, being primarily written in PHP and utilizing MySQL/MariaDB for its database, runs perfectly on a LAMP (Linux, Apache, MariaDB, and PHP) stack. Let’s begin by installing these essential components on your Debian server.

First, refresh your package index to ensure you’re getting the latest versions:

sudo apt update

Now, install the Apache web server, MariaDB database server, and all necessary PHP modules for Moodle. Confirm the installation by pressing ‘Y’ when prompted.

sudo apt install apache2 mariadb-server php-cli php-intl php-xmlrpc php-soap php-mysql php-zip php-gd php-tidy php-mbstring php-curl php-xml php-pear php-bcmath libapache2-mod-php

After installation, it’s good practice to verify that your core services are running and enabled to start on boot.

Check the Apache web server status:

sudo systemctl is-enabled apache2
sudo systemctl status apache2

You should see output confirming Apache is active and enabled, ready to serve web content.

Next, verify the MariaDB database server:

sudo systemctl is-enabled mariadb
sudo systemctl status mariadb

This output should indicate that MariaDB is also running smoothly.

Finally, confirm your PHP version and review the enabled modules. This helps ensure all Moodle dependencies are met.

php -v
php -m

You should see PHP 8.2 installed, along with crucial modules like ‘curl’, ‘exif’, and ‘date’.

Fortifying Your Server: Firewall Configuration

Installing and Configuring UFW

For any self-hosted application, robust server security is paramount. UFW (Uncomplicated Firewall) provides an intuitive way to manage network access. Let’s install and configure it to protect your Debian server.

Install UFW:

sudo apt install ufw

Once UFW is installed, open the necessary ports for SSH (secure remote access), HTTP (standard web traffic), and HTTPS (secure web traffic).

sudo ufw allow OpenSSH
sudo ufw allow 80/tcp
sudo ufw allow 443/tcp

You’ll see a confirmation like ‘Rules updated’. Now, enable the firewall:

sudo ufw enable

Confirm with ‘y’ when prompted. You should see ‘Firewall is active and enabled on system startup’.

Always verify your UFW status to ensure the rules are correctly applied:

sudo ufw status

This will show UFW as ‘active’ with OpenSSH, port ’80’, and port ‘443’ explicitly ‘ALLOWED’.

Database Setup: Optimizing MariaDB for Moodle

MariaDB Storage Engine Configuration

Before proceeding with your Moodle installation, it’s crucial to optimize MariaDB by setting ‘innodb’ as the default storage engine and enabling the ‘Barracuda’ file format. These settings are highly recommended for Moodle’s performance and data integrity.

Open the MariaDB server configuration file:

sudo nano /etc/mysql/mariadb.conf.d/50-server.cnf

Add the following lines under the `[mysqld]` section to enable Barracuda format and InnoDB:

innodb_file_format = Barracuda
default_storage_engine = innodb
innodb_large_prefix = 1
innodb_file_per_table = 1

Save the file and exit the editor.

Apply these changes by restarting the MariaDB server:

sudo systemctl restart mariadb

Securing Your MariaDB Installation

Securing your database is a critical step for any LMS solution. Run the `mariadb-secure-installation` utility to enhance your MariaDB server’s security:

sudo mariadb-secure-installation

Follow the prompts carefully:
– Press ENTER for the current root password (none by default for new installations).
– Enter ‘n’ to avoid switching to `unix_socket` authentication (we’ll set a password).
– Enter ‘Y’ to set a new MariaDB root password, then type and re-type your strong password.
– Enter ‘Y’ to remove anonymous users.
– Enter ‘Y’ to disallow remote root login.
– Enter ‘Y’ to remove the ‘test’ database.
– Enter ‘Y’ to reload privilege tables.

Creating Moodle’s Database and User

With MariaDB secured and configured, let’s create a dedicated database and user for your Moodle installation. This best practice isolates Moodle’s data for enhanced security and management.

Log in to the MariaDB server as the root user. Provide the root password you just set.

sudo mariadb -u root -p

Execute these SQL queries to create the `moodle` database and a new user `moodle` with a strong password (`MoodlePassw0rd` in this example – change this immediately to a unique, complex password).

CREATE DATABASE moodle DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
GRANT ALL ON moodle.* TO 'moodle'@'localhost' IDENTIFIED BY "MoodlePassw0rd";
FLUSH PRIVILEGES;

Verify that the `moodle` user has the correct privileges:

SHOW GRANTS FOR moodle@localhost;

Finally, exit the MariaDB client:

QUIT

Fine-Tuning PHP for Moodle Performance

Adjusting PHP Settings for Moodle

Moodle has specific PHP requirements for optimal operation, especially concerning memory and execution limits. Let’s adjust the `php.ini` file for your Apache setup.

Open the PHP configuration file for Apache:

sudo nano /etc/php/8.2/apache2/php.ini

Modify the following directives. Adjust `memory_limit` based on your server’s available RAM and expected user load.

memory_limit = 256M
upload_max_filesize = 60M
max_execution_time = 300
date.timezone = Europe/Amsterdam
max_input_vars = 5000

Save and close the file.

Pro Tip for Self-Hosted Moodle Performance: For significantly improved performance on your self-hosted LMS, ensure PHP’s OPcache is effectively utilized. While `php-opcache` is often installed with `libapache2-mod-php`, explicitly verify its configuration in `php.ini` (or a dedicated `opcache.ini`). Settings like `opcache.enable=1`, `opcache.memory_consumption`, and `opcache.revalidate_freq` can dramatically reduce Moodle’s loading times by caching compiled script bytecode.

After making these PHP adjustments, restart Apache to apply them:

sudo systemctl restart apache2

Deploying Moodle: Source Code and Directory Setup

Acquiring Moodle’s Latest Version

With your server environment ready, it’s time to download the Moodle source code. We’ll set up the installation in `/var/www/moodle` and the data directory in `/var/www/moodledata`.

Navigate to the web root directory and download the latest stable Moodle release:

cd /var/www
sudo wget https://download.moodle.org/download.php/direct/stable405/moodle-latest-405.tgz

Extract the downloaded archive. The original command extracts to a directory named `moodle` which will place your Moodle installation at `/var/www/moodle`.

tar -xf moodle-latest-405.tgz

Setting Up Moodle Directories and Permissions

Moodle requires a separate data directory outside the web-accessible area for security and proper function. Create this directory and assign correct ownership and permissions.

Create the Moodle data directory:

sudo mkdir -p /var/www/moodledata

Crucially, change the ownership of both the Moodle installation and data directories to `www-data` (the Apache user) and ensure proper read, write, and execute permissions.

sudo chown -R www-data:www-data /var/www/moodle /var/www/moodledata
sudo chmod -R u+rwx /var/www/moodle /var/www/moodledata

Apache Web Server Configuration

Creating a Virtual Host for Moodle

To make your Moodle installation accessible via your domain name, you need to configure an Apache virtual host. This tells Apache how to serve your Moodle application.

Create a new virtual host configuration file for Moodle:

sudo nano /etc/apache2/sites-available/moodle.conf

Insert the following configuration. Remember to replace `moodle.howtoforge.local` with your actual domain name.

<VirtualHost *:80>
    DocumentRoot /var/www/moodle/
    ServerName moodle.howtoforge.local
    ServerAdmin webmaster@yourdomain.com
    Options +FollowSymlinks
    AllowOverride All
    Require all granted
    ErrorLog ${APACHE_LOG_DIR}/moodle_error.log
    CustomLog ${APACHE_LOG_DIR}/moodle_access.log combined
</VirtualHost>

Save the file and exit.

Activating Apache Modules and Site Configuration

Enable the `rewrite` module (essential for clean URLs in Moodle) and activate your newly created Moodle virtual host.

sudo a2enmod rewrite
sudo a2ensite moodle.conf

Always test your Apache configuration for syntax errors before restarting the service:

sudo apachectl configtest

If you see ‘Syntax is OK’, you’re good to go. Restart Apache to apply all changes:

sudo systemctl restart apache2

Securing Your Self-Hosted Moodle with HTTPS

Implementing SSL/TLS with Certbot

For any public-facing LMS solution, securing your traffic with HTTPS is non-negotiable. Certbot, with its Let’s Encrypt integration, makes acquiring free SSL/TLS certificates straightforward. This step is vital for protecting user data and building trust.

Install Certbot and its Apache plugin:

sudo apt install certbot python3-certbot-apache

Once installed, execute Certbot to generate and install SSL certificates for your Moodle domain. Replace `moodle.howtoforge.local` with your domain and `your-email@example.com` with your actual email address.

sudo certbot --apache --agree-tos --no-eff-email -m your-email@example.com -d moodle.howtoforge.local

Certbot will automatically configure Apache to serve your Moodle site over HTTPS, redirecting HTTP traffic. Your new SSL certificates will be located in `/etc/letsencrypt/live/yourdomain.com/`.

Completing the Moodle Web Installation Wizard

With all server-side configurations complete, it’s time to finalize your Moodle installation through its intuitive web-based wizard.

Open your web browser and navigate to your Moodle domain (e.g., `https://moodle.yourdomain.com`). You will be greeted by the Moodle installation wizard.

1. Select your preferred language and click ‘Next’.
2. Confirm your Moodle web address and the data directory (`/var/www/moodledata`).
3. Choose ‘MariaDB’ as your database driver.
4. Enter the MariaDB database details you configured earlier (database name: `moodle`, user: `moodle`, password: `MoodlePassw0rd` – remember to use your actual password).
5. Accept the copyright notice by clicking ‘Continue’.
6. On the ‘Server checks’ page, verify that all items show a ‘OK’ status, confirming your Debian server meets all Moodle requirements.
7. The installation process will now begin, populating your database and setting up Moodle’s core files.
8. Once complete, create your Moodle administrator account by entering a username, email, and a strong password.
9. Finally, provide your Moodle site information, including the site name and a short name.

Congratulations! You should now be looking at your Moodle admin dashboard, ready to create courses and manage your new self-hosted LMS.
