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 updatesudo 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.
