🚀 Ultimate Step‑by‑Step Installation

1. System Update & Core Packages

Explanation
Install PHP8.1 and basic tools required to support multi-server runtimes.
bash 
sudo apt update && sudo apt upgrade -y
sudo apt install apache2 mariadb-server mariadb-client -y
sudo apt install php8.1 php8.1-cli php8.1-common php8.1-mysql php8.1-xml php8.1-curl php8.1-gd php8.1-intl php8.1-mbstring php8.1-zip php8.1-soap php8.1-bcmath libapache2-mod-php8.1 -y
sudo apt install git nano cron sendmail certbot python3-certbot-apache -y
sudo a2enmod rewrite ssl
sudo systemctl restart apache2

2. Database & Secure User (MariaDB)

DB settings
Provision the database `moodle_demo` with `utf8mb4` encoding support.
sql 
CREATE DATABASE moodle_demo CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
CREATE USER 'moodleDemo2026'@'localhost' IDENTIFIED BY '2026PassDemo!!';
GRANT ALL PRIVILEGES ON moodle_demo.* TO 'moodleDemo2026'@'localhost';
FLUSH PRIVILEGES;
EXIT;

3. PHP Tuning (upload, memory, max vars)

Tuning reasons
Avoid server timeouts during large backups or SCORM uploads.
bash 
sudo nano /etc/php/8.1/apache2/php.ini
# Set values:
upload_max_filesize = 1080M
post_max_size = 1080M
max_execution_time = 3600
memory_limit = 512M
max_input_vars = 5000
max_input_time = 300
sudo systemctl restart apache2

4. Clone Moodle 5.0 (MOODLE_500_STABLE)

Target directory
Cloning into `moodl_ulo2026Demo` to preserve exact system structures.
bash 
cd /var/www
sudo git clone -b MOODLE_500_STABLE git://git.moodle.org/moodle.git moodl_ulo2026Demo
sudo chown -R www-data:www-data /var/www/moodl_ulo2026Demo
sudo chmod -R 755 /var/www/moodl_ulo2026Demo

5. 100GB Data Disk (persistent mount)

Disk mount
Format external drive as ext4 and mount persistent volume under `/var/moodledata`.
bash 
sudo fdisk /dev/sdb   # n, p, enter, w
sudo mkfs.ext4 /dev/sdb1
sudo mkdir -p /var/moodledata
sudo mount /dev/sdb1 /var/moodledata
# get UUID: sudo blkid /dev/sdb1
echo "UUID=YOUR-UUID /var/moodledata ext4 defaults,noatime 0 2" | sudo tee -a /etc/fstab
sudo chown -R www-data:www-data /var/moodledata
sudo chmod -R 770 /var/moodledata

6. Moodle config.php & wwwroot

php 
cd /var/www/moodl_ulo2026Demo
sudo cp config-dist.php config.php
sudo nano config.php
# Insert config:
$CFG->dbtype    = 'mariadb';
$CFG->dbhost    = 'localhost';
$CFG->dbname    = 'moodle_demo';
$CFG->dbuser    = 'moodleDemo2026';
$CFG->dbpass    = '2026PassDemo!!';
$CFG->prefix    = 'mdl_';
$CFG->wwwroot   = 'https://classroom.demodemo.com';
$CFG->dataroot  = '/var/moodledata';
$CFG->directorypermissions = 02775;
$CFG->disablelogintoken = true;

7. Apache VirtualHost & SSL (Let's Encrypt)

bash 
sudo nano /etc/apache2/sites-available/moodle.conf
# Paste vhost config
sudo a2ensite moodle.conf
sudo systemctl reload apache2
sudo certbot --apache -d classroom.demodemo.com
sudo certbot renew --dry-run

8. Cron + background tasks

bash 
sudo crontab -u www-data -e
# Insert line:
* * * * * /usr/bin/php /var/www/moodl_ulo2026Demo/admin/cli/cron.php > /dev/null
sudo systemctl enable cron
sudo -u www-data php /var/www/moodl_ulo2026Demo/admin/cli/cron.php

9. Final Permissions & Validation

bash 
sudo chown -R www-data:www-data /var/moodledata /var/www/moodl_ulo2026Demo
sudo systemctl restart apache2 mariadb
# Test database
php /var/www/moodl_ulo2026Demo/admin/cli/check_database_schema.php
