    How to Install Apache & PHP-FPM on Debian 12/11

    By RahulAugust 3, 20233 Mins Read

    Apache is one of the most popular open-source web servers available. It’s incredibly powerful, capable of serving a high number of requests per second. PHP-FPM is an efficient method used to deliver PHP content on high-traffic servers. When combined, they can efficiently serve dynamic PHP applications.

    In this article, we will guide you on how to install Apache and PHP-FPM on Debian 12/11 Linux system.

    Prerequisites

    • A running Debian 12/11 Linux system.
    • Root or sudo access to the system.

    Step 1: Update the System

    First, it is always a good practice to update the system packages. Run the following command in your terminal:

    sudo apt update 
    sudo apt upgrade -y 
    

    This command will fetch the list of available packages and update them.

    Step 2: Install Apache

    After updating the system, you can install Apache with the following command:

    sudo apt install apache2 -y 
    

    When the installation is complete, you can check the status of Apache using the command:

    sudo systemctl status apache2 
    

    If Apache is running properly, you will see “active (running)” in the output.

    Step 3: Install PHP-FPM and necessary PHP modules

    The next step is to install PHP-FPM. Debian 12/11 may already have PHP in its repository. Install PHP-FPM and necessary PHP modules with the following command:

    sudo apt install php-fpm php-mysql -y 
    

    This will install PHP-FPM and the PHP MySQL extension. If you need any other PHP extensions, you can install them similarly.

    Check the status of the PHP-FPM service by running:

    sudo systemctl status php7.4-fpm 
    

    The PHP-FPM service should now be active and running.

    Step 4: Configuring Apache to use PHP-FPM

    By default, Apache uses the PHP module to process PHP files. To change this to PHP-FPM, we first need to disable the PHP module. Execute the following command:

    sudo a2dismod php7.4 
    

    Next, enable the necessary proxy modules and the proxy_fcgi module:

    sudo a2enmod proxy_fcgi setenvif 
    

    Now, we need to enable the PHP-FPM configuration for Apache.

    sudo a2enconf php7.4-fpm 
    

    Ensure you’ve enabled the php7.4-fpm.conf file. It’s provided by the PHP-FPM package and instructs Apache to pass PHP requests to FPM via a Unix socket.

    Restart Apache to implement these changes:

    sudo systemctl restart apache2 
    

    Step 5: Testing the Configuration

    After configuring Apache to use PHP-FPM, we should test it to ensure it works correctly. We can create a phpinfo() file, which displays the details of your PHP configuration. Run the following command to create the file:

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

    Now, open a web browser and navigate to http://your-server-ip/info.php. You should see the PHP configuration page showing that the Server API is FPM/FastCGI, which indicates that Apache is indeed using PHP-FPM.

    Conclusion

    You have successfully installed Apache with PHP-FPM on Debian 12/11. This powerful combination allows you to serve dynamic PHP applications efficiently. Always ensure to keep your system and services updated for the best security and performance.

    This tutorial provided a basic configuration to get you started. However, both Apache and PHP-FPM have a wide range of configurations that can be adjusted according to your specific needs. Make sure to look into further optimizations and security measures.
