Install APCu in cPanel server

This post describes how to install APCu in cPanel server. APCu is designed to be used alongside OpCache if you need data caching. The APCu was developed by Joe Watkins in response to OPcache.

Please login to the server via SSH and install the pcre-devel package prior to the APCu installation. You can do it using the following command. This is applicable for EasyApache 3 and EasyApache 4. 

 
yum install pcre-devel

Install APCu on cPanel using EasyApache 3

Please install APCu using PECL repository. You can do it using the following command.

 
pecl install channel://pecl.php.net/APCu-4.0.10

Also, the newer versions of APCu (Latest version is APCu 5.1.3) needs PHP 7.0.0-dev. The latest available version of PHP is PHP 5.6.19 in EasyApache 3. That’s the reason why we are installing the APCu version 4.0.10.

Please restart Apache service once the APCu installation completed.

 
/etc/init.d/httpd restart
