How to Install LAMP Stack on Ubuntu / Debian / AlmaLinux VPS

If you're looking to host websites or web applications on your server, installing the LAMP stack is an essential step. LAMP stands for Linux, Apache, MySQL (or MariaDB), and PHP (or Perl/Python). This tutorial will guide you through the installation process for Ubuntu, Debian, and AlmaLinux.

Prerequisites

Before you begin, make sure you have:

• Access to your server or local machine with one of the following operating systems:
  • Ubuntu (20.04 or later)
  • Debian (10 or later)
  • AlmaLinux (8 or later)
• A user account with sudo privileges.
• An active internet connection.

Step 1: Update Your System

Before installing any packages, it’s a good practice to update your package index. Run the following command:

For Ubuntu/Debian:

sudo apt update && sudo apt upgrade -y

For AlmaLinux:

sudo dnf update -y

Step 2: Install Apache Web Server

Apache is one of the most widely used web servers. You can install it with the following commands:

For Ubuntu/Debian:

sudo apt install apache2 -y

For AlmaLinux:

sudo dnf install httpd -y

After installation, start the Apache service and enable it to launch at boot:

sudo systemctl start apache2   # For Ubuntu/Debian
sudo systemctl start httpd     # For AlmaLinux

sudo systemctl enable apache2   # For Ubuntu/Debian
sudo systemctl enable httpd     # For AlmaLinux

Verify the installation by opening your web browser and navigating to http://your_server_ip. You should see the Apache2 Ubuntu Default Page or a similar confirmation page for AlmaLinux.

Step 3: Install MySQL / MariaDB

For database management, we will install either MySQL or MariaDB. MariaDB is a popular drop-in replacement for MySQL that is often recommended.

For MySQL on Ubuntu/Debian:

sudo apt install mysql-server -y

For MariaDB on AlmaLinux:

sudo dnf install mariadb-server -y

Once installed, start the service and enable it to run at boot:

sudo systemctl start mysql   # For Ubuntu/Debian
sudo systemctl start mariadb # For AlmaLinux

sudo systemctl enable mysql   # For Ubuntu/Debian
sudo systemctl enable mariadb # For AlmaLinux

Secure your installation by running:

sudo mysql_secure_installation

Follow the on-screen prompts to set a root password and remove test databases, etc.

Step 4: Install PHP

Now, let’s install PHP, which is the programming language that will work alongside Apache and MySQL. You can also install additional PHP modules as needed.

For Ubuntu/Debian:

sudo apt install php libapache2-mod-php php-mysql -y

For AlmaLinux:

sudo dnf install php php-mysqlnd -y

To install additional PHP extensions, you can use:

sudo apt install php-<extension_name> -y  # For Ubuntu/Debian
sudo dnf install php-<extension_name> -y  # For AlmaLinux

Step 5: Test PHP

To verify that PHP is working with Apache, create a PHP info file:

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

Now, visit http://your_server_ip/info.php in your web browser. You should see the PHP information page. Remember to delete this file after testing for security purposes:

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

Step 6: Adjust Firewall Settings (if applicable)

If you have a firewall enabled, make sure to allow HTTP and HTTPS traffic:

For Ubuntu/Debian (using UFW):

sudo ufw allow 'Apache Full'

For AlmaLinux (using firewalld):

sudo firewall-cmd --zone=public --add-service=http --permanent
sudo firewall-cmd --zone=public --add-service=https --permanent
sudo firewall-cmd --reload

Great! You have successfully installed the LAMP stack on your server. This powerful framework will allow you to host dynamic websites and applications with a solid foundation. Remember to secure your server properly and keep your packages updated.

Next Steps

• You may want to explore additional PHP modules and configurations.
• Consider installing phpMyAdmin for managing your databases through a web interface.
• Always keep an eye on security best practices to secure your applications and data.

• Troubleshooting Tips

• If you encounter issues, check if Apache, MySQL, and PHP services are running properly.
• Look into the respective error logs for Apache (/var/log/apache2/error.log for Ubuntu/Debian and /var/log/httpd/error_log for AlmaLinux) for more insight.
