Opcache is a powerful PHP extension used to increase PHP performance by storing precompiled script bytecode in shared memory. So PHP does not need to load and parse scripts on each request. This will speed up the performance of PHP based applications.

In this tutorial, we will show you how to install and enable the Opcache PHP extension with Apache and Nginx on Ubuntu 20.04.

Prerequisites

  • A server running Ubuntu 20.04.
  • A root password is configured the server.

Install Opcache with Apache

In this section, we will show you how to install and enable the Opcache PHP module on the server running Apache.

Once the Opcache is installed, edit the php.ini file to enable the Opcache extension.

nano /etc/php/7.4/apache2/php.ini

Change the following lines for good performance.

opcache.enable=1
opcache.memory_consumption=128
opcache.max_accelerated_files=3000
opcache.revalidate_freq=200

Save and close the file then restart the Apache service to apply the configuration changes:

systemctl restart apache2

Install Opcache with Nginx

In this section, we will show you how to install and enable the Opcache PHP module on the server running Nginx.

opcache.enable=1
opcache.memory_consumption=128
opcache.max_accelerated_files=3000
opcache.revalidate_freq=200

Save and close the file then restart the Nginx and PHP-FPM service to apply the configuration changes:
