The LAMP stack (Linux, Apache, MySQL/MariaDB, PHP) is a popular open-source web development platform. This guide walks through deploying a LAMP server on Debian, covering system preparation, component installation, configuration, and security hardening.
Before installing any software, update your system’s package list and upgrade existing packages to their latest versions. This ensures compatibility and security.
sudo apt update && sudo apt upgrade -y
Apache is the most widely used web server for Debian. Install it using apt, start the service, and enable it to launch at boot.
sudo apt install apache2 -y
sudo systemctl start apache2
sudo systemctl enable apache2
Verify Apache is running by visiting your server’s IP in a browser—you should see the default Apache welcome page.
Debian uses MariaDB (a MySQL fork) as the default database server. Install it and run the mysql_secure_installation script to enhance security (e.g., set a root password, remove anonymous users).
sudo apt install mariadb-server -y
sudo mysql_secure_installation
After setup, log in to MariaDB to verify:
sudo mysql -u root -p
Create a database and user for your application (replace placeholders with secure values):
CREATE DATABASE my_database;
CREATE USER 'my_user'@'localhost' IDENTIFIED BY 'StrongPassword123!';
GRANT ALL PRIVILEGES ON my_database.* TO 'my_user'@'localhost';
FLUSH PRIVILEGES;
EXIT;
PHP is the scripting engine for dynamic content. Install PHP and common extensions (e.g., mysql for database connectivity, gd for image processing).
sudo apt install php libapache2-mod-php php-mysql php-cli php-gd php-mbstring php-curl php-xml -y
Restart Apache to load PHP modules:
sudo systemctl restart apache2
Test PHP by creating an info.php file in the web root (/var/www/html):
echo "<?php phpinfo(); ?>" | sudo tee /var/www/html/info.php
Visit http://your_server_ip/info.php to confirm PHP is working.
Ensure Apache can handle PHP files by modifying the default virtual host configuration. Edit the file and enable .php file handling:
sudo nano /etc/apache2/sites-available/000-default.conf
Add the following inside the <VirtualHost *:80> block (under <Directory /var/www/html>):
<FilesMatch \.php$>
SetHandler application/x-httpd-php
</FilesMatch>
Save the file, then restart Apache:
sudo systemctl restart apache2
Allow HTTP (port 80) and HTTPS (port 443) traffic to enable web access:
sudo apt install ufw -y
sudo ufw allow 'Apache Full'
sudo ufw enable
mysql_secure_installation).mysqldump.Regularly run sudo apt update && sudo apt upgrade -y to patch vulnerabilities.
phpMyAdmin provides a web-based interface for managing MySQL/MariaDB. Install it and configure Apache:
sudo apt install phpmyadmin -y
During installation, select Apache as the web server and configure a database for phpMyAdmin. Access it via http://your_server_ip/phpmyadmin.
Use Certbot to obtain a free SSL certificate and redirect HTTP to HTTPS for secure connections:
sudo apt install certbot python3-certbot-apache -y
sudo certbot --apache
Follow the prompts to secure your domain. Certbot will automatically configure HTTPS and redirect traffic.
By following these steps, you’ll have a fully functional LAMP server on Debian, ready to host dynamic web applications. Adjust configurations (e.g., PHP versions, database settings) based on your application requirements.
