Let’s configure the Apache VirtualHost to run with FPM/FastCGI. For this tutorial, we use default VirtualHost. Edit VirtualHost host configuration file in text editor. You can create new VirtualHost as per your requirements, so make sure to enable any new VirtualHost.

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

Test Setup

Create a PHP script with phpinfo() function and place it to your server document root. Use below command to do it.

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

Open a web browser access the info.php using server IP address (for default VirtualHost) for your configured domain in Apache VirtualHost.
