Step 1: Install Apache

Apache is a popular web server that's used to serve web pages. To install Apache on Debian 11, open the terminal and run the following command:

sudo apt update
sudo apt install apache2

After the installation is complete, start the Apache service by running the following command:

To verify that Apache is installed and running correctly, open your web browser and navigate to "http://localhost". If Apache is installed and running correctly, you should see the Apache default page.

Step 2: Install MySQL

MySQL is a popular relational database management system that's commonly used for storing data for web applications. To install MySQL on Debian 11, open the terminal and run the following command:

sudo apt install mysql-server

After the installation is complete, start the MySQL service by running the following command:

Next, run the following command to secure the MySQL installation:

sudo mysql_secure_installation

This command will guide you through the process of setting the MySQL root password, removing anonymous users, and other security-related tasks.

Step 3: Install PHP

PHP is a popular server-side scripting language that's used for building dynamic web pages. To install PHP on Debian 11, open the terminal and run the following command:

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

After the installation is complete, restart the Apache service by running the following command:

sudo systemctl restart apache2

Step 4: Test the LAMP Stack

To test the LAMP stack, create a new PHP file named "info.php" in the Apache document root directory (/var/www/html) with the following contents:

<?php phpinfo(); ?>

Save the file and then open your web browser and navigate to "http://localhost/info.php". If the LAMP stack is installed and running correctly, you should see the PHP information page.

Step 5: Optional - Install phpMyAdmin

phpMyAdmin is a web-based tool for managing MySQL databases. To install phpMyAdmin on Debian 11, open the terminal and run the following command:

sudo apt install phpmyadmin

During the installation process, you will be asked to configure phpMyAdmin. Choose Apache as the web server, and then follow the prompts to complete the configuration.
