In this article, AZDIGI will show you how to install OPCACHE to Cyber Panel to improve PHP efficiency many times and help reduce CPU load for your VPS/server.


When installing CyberPanel, the PHP version installed by the system will be 7.1 and if you want to change this default version, you can see the instructions below:

With Cyber Panel, you can choose PHP versions simply because Cyber Panel supports versions from 5.3 => 7.4. To customize the PHP version for your website, you can refer to the instructions below:

And one more note is that OPcache will be installed separately for each PHP version. For example, if you use PHP 7.1 version, when you install OPcache, OPcache will only work in PHP 7.1 but not on PHP other versions. If you want to use it in other versions, you need to install it similarly. So what is OPcache PHP Extension and how to install it, please continue reading this article.

What is OPcache?

Originally called Zend Optimizer +, OPcache (introduced in PHP 5.5.0) is a powerful PHP extension built to enhance PHP performance, thus increasing overall application performance. It is available as an extension through PECL for PHP versions 5.2, 5.3 and 5.4. It works by storing precompiled script-bytecode in shared memory or RAM, thus eliminating the need for PHP to load and parse the script on each request.

Features of OPcache:

  • Helps reduce %CPU usage for the server.
  • Reduce TTFB of all PHP sites on the server.
  • Increase website loading speed.
