LAMP is the foundational stack that powers over half the internet:

Linux (Operating System)
Apache (Web Server)
MariaDB/MySQL (Database)
PHP (Programming Language)

This guide covers Debian 12+, Ubuntu 22.04+, and Linux Mint 21+ with modern package versions and security best practices.

Update your system first:

sudo apt update && sudo apt upgrade -y

The magic command:

sudo apt install apache2 mariadb-server php libapache2-mod-php php-mysql php-cli php-curl php-gd php-mbstring php-xml php-zip -y

What this installs:

• apache2: The Apache web server (version 2.4+)
• mariadb-server: Modern drop-in replacement for MySQL (version 10.11+)
• php: PHP 8.1+ (8.2/8.3 on newer systems) with core functionality
• libapache2-mod-php: Apache module to process PHP files
• php-mysql: PHP module for MariaDB/MySQL connectivity
• Plus essential extensions: cURL, GD graphics, MBstring, XML, Zip

Test Apache (Web Server):

sudo systemctl status apache2
# If not running: sudo systemctl start apache2
# Enable auto-start: sudo systemctl enable apache2

Open your browser to http://localhost or your server's IP address. You should see the Apache default page.

Test PHP:

Create a test file:

echo "<?php phpinfo(); ?>" | sudo tee /var/www/html/phpinfo.php

Visit http://localhost/phpinfo.php. You'll see a detailed PHP configuration page. Delete this file after testing:

sudo rm /var/www/html/phpinfo.php

Configure MariaDB (Security Hardening):

Run the interactive security script:

sudo mysql_secure_installation

Follow prompts to:

1. Set a strong root password (different from your system password)
2. Remove anonymous users (Y)
3. Disallow root login remotely (Y)
4. Remove test database (Y)
5. Reload privilege tables (Y)

1. Set Proper Permissions:

sudo chown -R $USER:$USER /var/www/html
sudo chmod -R 755 /var/www/html

2. Create a Virtual Host (Recommended for multiple sites):

Create a configuration file:

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

Add this configuration (replace yourdomain with your actual domain):

<VirtualHost *:80>
    ServerAdmin admin@yourdomain.com
    ServerName yourdomain.com
    ServerAlias www.yourdomain.com
    DocumentRoot /var/www/yourdomain
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

3. Enable the Site:

sudo mkdir /var/www/yourdomain
sudo a2ensite yourdomain.conf
sudo a2dissite 000-default.conf
sudo systemctl reload apache2

4. Create a PHP Test Page:

echo '<?php
echo "<h1>LAMP Stack is Working!</h1>";
echo "<p>Server Time: " . date("Y-m-d H:i:s") . "</p>";

// Test database connection
$conn = new mysqli("localhost", "root", "YOUR_PASSWORD");
if ($conn->connect_error) {
    echo "<p style=\"color:red\">Database connection failed: " . $conn->connect_error . "</p>";
} else {
    echo "<p style=\"color:green\">Database connection successful!</p>";
    $conn->close();
}
?>' | sudo tee /var/www/yourdomain/index.php

Replace YOUR_PASSWORD with your MariaDB root password.

1. Configure PHP for Production:

Edit the PHP configuration:

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

Find and change these lines (PHP version might be 8.1 or 8.3):

expose_php = Off
max_execution_time = 30
upload_max_filesize = 2M
post_max_size = 8M
display_errors = Off
log_errors = On
error_log = /var/log/php_errors.log

Create the error log and restart Apache:

sudo touch /var/log/php_errors.log
sudo chown www-data:www-data /var/log/php_errors.log
sudo systemctl restart apache2

2. Install Fail2ban (Brute Force Protection):

sudo apt install fail2ban -y
sudo systemctl enable fail2ban

3. Enable HTTPS with Let's Encrypt:

sudo apt install certbot python3-certbot-apache -y
sudo certbot --apache -d yourdomain.com -d www.yourdomain.com

Follow the interactive prompts to get a free SSL certificate.

4. Configure Firewall (UFW):

sudo ufw allow 22/tcp comment 'SSH'
sudo ufw allow 80/tcp comment 'HTTP'
sudo ufw allow 443/tcp comment 'HTTPS'
sudo ufw --force enable
sudo ufw status

Common Issues & Solutions:

Apache won't start:

sudo apache2ctl configtest  # Check configuration
sudo systemctl status apache2 --full  # Detailed status
sudo journalctl -xe -u apache2  # View logs

PHP file downloads instead of executes:

sudo a2enmod php  # Ensure PHP module is enabled
sudo systemctl restart apache2

Database connection issues:

sudo systemctl status mariadb
sudo mysql -u root -p  # Test login
# If you forgot password: sudo mysql --skip-grant-tables

Useful Maintenance Commands:

# Check disk space
df -h

# Check memory usage
free -h

# Update all packages weekly
sudo apt update && sudo apt upgrade -y

# Backup website and database
sudo tar -czf /backup/website_$(date +%Y%m%d).tar.gz /var/www/yourdomain
sudo mysqldump -u root -p --all-databases > /backup/database_$(date +%Y%m%d).sql

Your LAMP stack is now fully installed, secured, and optimized for production. You can deploy WordPress, Laravel, custom PHP applications, or any web software that requires this standard stack.

Next Steps:

• Install WordPress: wget https://wordpress.org/latest.tar.gz
• Set up phpMyAdmin for database management
• Configure automated backups
• Set up monitoring with UptimeRobot or similar
