Why use mod_fcgid and PHP-FPM?
mod_fcgid is a high-performance alternative to mod_cgi or mod_cgid modules in Apache. It allows the execution of FastCGI applications, such as PHP, in a separate process for improved performance and resource management. PHP-FPM, on the other hand, is a FastCGI Process Manager for PHP. It provides advanced features, including process pooling and dynamic process management, which enhance the scalability and efficiency of PHP applications.
By installing mod_fcgid and PHP-FPM, you can take advantage of their combined benefits to optimize the execution of PHP scripts on your CentOS 8 server. This will result in faster processing times, reduced resource consumption, and improved overall performance of your web applications.
Configuring Apache with PHP-FPM
Once you have installed PHP-FPM on your CentOS 8 server, the next step is to configure Apache to use PHP-FPM. This will allow Apache to pass all requests for PHP files to the PHP-FPM handler, ensuring that PHP scripts are executed properly.
To configure Apache with PHP-FPM, you will need to modify two configuration files: the PHP-FPM configuration file (/etc/php-fpm.d/www.conf) and the Apache configuration file (/etc/httpd/conf.modules.d/10-fcgid.conf).
In the PHP-FPM configuration file, you can adjust settings such as the number of child processes, the user and group that PHP-FPM runs as, and the listening address and port. Make sure to save the changes after modifying the file.
In the Apache configuration file, you will need to add a few lines of code to enable the FastCGI module and specify the location of the PHP-FPM socket file. This will ensure that Apache communicates with PHP-FPM correctly.
Modifying the PHP-FPM Configuration File
Open the PHP-FPM configuration file (/etc/php-fpm.d/www.conf) using a text editor such as nano or vi:
sudo nano /etc/php-fpm.d/www.conf
Scroll down to find the following lines:
;listen = /run/php-fpm/www.sock
;listen.owner = nobody
;listen.group = nobody
;listen.mode = 0660
Remove the semicolons (;) from the beginning of these lines to uncomment them. Then, modify the values according to your configuration. For example:
listen = /var/run/php-fpm/php-fpm.sock
listen.owner = apache
listen.group = apache
listen.mode = 0660
Save the changes and exit the text editor.
Modifying the Apache Configuration File
Open the Apache configuration file (/etc/httpd/conf.modules.d/10-fcgid.conf) using a text editor:
sudo nano /etc/httpd/conf.modules.d/10-fcgid.conf
Add the following lines at the end of the file:
SetHandler "proxy:unix:/var/run/php-fpm/php-fpm.sock|fcgi://localhost/"
ProxyPassMatch ^/(.+\\.php(/.*)?)$ unix:/var/run/php-fpm/php-fpm.sock|fcgi://localhost/var/www/html/$1
Save the changes and exit the text editor.
After configuring Apache with PHP-FPM, you can check for any syntax errors in the configuration files by running the following command:
sudo httpd -t
If there are no errors, you can restart the Apache service to apply the changes:
sudo systemctl restart httpd
With Apache now properly configured to use PHP-FPM, you can start serving PHP-based web applications on your CentOS 8 server.
Testing PHP Functionality
Once you have successfully configured Apache with PHP-FPM on your CentOS 8 server, it is essential to test the PHP functionality to ensure that everything is set up correctly. Verifying PHP installation on CentOS 8 is a crucial step in the process.
To test PHP functionality, you can create a PHP info file. Start by running the command sudo touch /var/www/html/example.com/public_html/info.php to create a new file. Then, add the PHP info code <?php phpinfo(); ?> to the file.
After creating the info file, you can access it through a web browser by navigating to www.example.com/info.php. This will display a comprehensive overview of your PHP installation, including information about PHP modules, configuration options, and server settings. If the page loads successfully and you can see the PHP info, it means that your PHP installation is working correctly.
Summary:
- After configuring Apache with PHP-FPM, it is important to test the PHP functionality.

sudo touch /var/www/html/example.com/public_html/info.phpand add the code<?php phpinfo(); ?>to the file. - Access the info file through a web browser by navigating to www.example.com/info.php.
- If the page loads successfully and displays the PHP info, your PHP installation is working correctly.
Configuring PHP Pools
Once you have successfully installed PHP-FPM on your CentOS 8 server and configured Apache with PHP-FPM, it's time to set up PHP pools. PHP-FPM allows you to create and manage pools, which are used to run PHP processes for different websites or applications. By configuring PHP pools, you can optimize performance and resource allocation for each specific pool.
Creating a PHP Pool Configuration File
To create a PHP pool configuration file for your domain, you need to make a copy of the original pool file. This can be done by running the command sudo cp /etc/php-fpm.d/www.conf /etc/php-fpm.d/mydomain.conf. Replace "mydomain" with the name of your domain.
Next, you can edit the newly created pool file to set the necessary parameters. Some important settings to consider include the pool name, user and group ownership, listen address and port, and the maximum number of child processes. Make sure to customize these settings according to your specific requirements.
Restarting PHP-FPM and Updating Virtual Host
After configuring the PHP pool, you need to restart the PHP-FPM service to apply the changes. You can do this by running the command sudo systemctl restart php-fpm. Once the service is restarted, it's time to update the virtual host file for your domain to use the new PHP-FPM pool.
Note: The location of the virtual host file may vary depending on your server configuration. By default, the Apache virtual host files are located in the
/etc/httpd/conf.d/directory.
Edit the virtual host file for your domain and modify the ProxyPassMatch directive to point to the PHP-FPM pool. The syntax should be similar to ProxyPassMatch ^/(.*\.php(/.*)?)$ fcgi://127.0.0.1:9000/path/to/your/domain. Make sure to replace 127.0.0.1:9000/path/to/your/domain with the correct address and path for your PHP-FPM pool.
Save the changes to the virtual host file, and then restart the Apache web server by running the command sudo systemctl restart httpd. This will ensure that the changes take effect and your domain is now using the newly configured PHP-FPM pool.
