Downloading and installing Moodle involves several steps, including setting up a web server, database, and PHP. Below is a step-by-step guide to install Moodle on your system.

Prerequisites

Before installing Moodle, ensure your server meets the following requirements:

• Web Server: Apache, Nginx, or IIS.
• Database: MySQL, MariaDB, PostgreSQL, or Microsoft SQL Server.
• PHP: Version 7.4 to 8.2 (check Moodle Docs for the latest version).
• PHP Extensions: Required extensions like curl, xml, mbstring, zip, gd, intl, etc.
• Memory Limit: At least 256MB (php.ini setting: memory_limit = 256M).

Step 1: Download Moodle

1. Go to the official Moodle website: https://download.moodle.org/
2. Choose the latest stable version (e.g., Moodle 4.x).
3. Download:

• ZIP file (for Windows/Linux manual install).
• Git (for developers).
• Command-line download (Linux):
  sh wget https://download.moodle.org/download.php/direct/stable401/moodle-latest-401.zip unzip moodle-latest-401.zip

Step 2: Set Up Web Server & Database

For Linux (Apache, MySQL, PHP)

1. Install LAMP Stack:

   sudo apt update
   sudo apt install apache2 mysql-server php php-cli php-mysql php-curl php-zip php-xml php-mbstring php-gd php-intl

2. Secure MySQL:

   sudo mysql_secure_installation

3. Create a Moodle database:

   CREATE DATABASE moodle DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
   CREATE USER 'moodleuser'@'localhost' IDENTIFIED BY 'yourpassword';
   GRANT ALL PRIVILEGES ON moodle.* TO 'moodleuser'@'localhost';
   FLUSH PRIVILEGES;
   EXIT;

For Windows (XAMPP/WAMP)

1. Install XAMPP (includes Apache, MySQL, PHP).
2. Start Apache and MySQL from the XAMPP control panel.
3. Create a Moodle database using phpMyAdmin.

Step 3: Install Moodle

1. Extract Moodle into your web server directory:

• Linux: /var/www/html/moodle
• Windows: C:\xampp\htdocs\moodle

1. Set permissions (Linux):

   sudo chown -R www-data:www-data /var/www/html/moodle/
   sudo chmod -R 755 /var/www/html/moodle/

3. Run the Moodle installer:

• Open a browser and go to http://localhost/moodle.
• Follow the installation wizard:
  • Select language.
  • Set database details (MySQL username/password).
  • Configure admin account.
  • Complete setup.

Step 4: Configure Cron Jobs (Automated Tasks)

Moodle requires a cron job to run scheduled tasks.

• Linux (add to crontab):

  crontab -e
  * * * * * /usr/bin/php /var/www/html/moodle/admin/cli/cron.php >/dev/null

• Windows: Use Windows Task Scheduler to run php moodle\admin\cli\cron.php.

Step 5: Secure Moodle

• Enable HTTPS (SSL certificate).
• Restrict access to config.php (set permissions to 640).
• Regularly update Moodle (admin > notifications).

Alternative: Quick Install (Bitnami Moodle)

For a hassle-free setup, use Bitnami Moodle Stack:

• Download from Bitnami Moodle.
• Run the installer (includes all dependencies).

Troubleshooting

• PHP errors: Check php.ini settings (max_execution_time, memory_limit).
• Database issues: Verify MySQL credentials.
• Permissions: Ensure moodledata directory is writable.
