For the PHP installation we recommend to use ppa:ondrej/php PPA. Execute below couple of commands to add the PPA to your system.

sudo apt install software-properties-common
sudo add-apt-repository ppa:ondrej/php

Then install PHP 7.4 (or required version) the latest version available on the day of writing this tutorial. Simply execute follows commands for the installation of PHP and PHP-FPM packages.

sudo apt update
sudo apt install php7.4 php7.4-fpm

After installing the packages php7.4-fpm service will automatically be started. To make sure, type:

Step 3 – Apache Configuration

Now, You need to enable some of the Apache modules required for the FastCGI confiugration. You can enable the requird module by running command:

sudo a2enmod actions fcgid alias proxy_fcgi

Then configure Apache Virtual Host to run with FPM/FastCGI. For this tutorial, we use default VirtualHost. Edit VirtualHost host configuration file in a text editor. You can also create a new configuration as per your choice.

sudo vim /etc/apache2/sites-available/000-default.conf

Update the configuration as followings.

Save your changes to the configuration file and restart Apache to reload the changes.

sudo systemctl restart apache2

Step 4 – Verify Setup

Apache with PHP-FPM configuration has been done. Now all the PHP files will be run with the FPM.

To verify these settigns, create a PHP script with phpinfo() function and place it to your server document root. Use below command to create file:

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

Then access the info.php using server IP address (for default VirtualHost) or your configured domain in Apache VirtualHost.
