How To Install XCache on CentOS 7

Install XCache on CentOS 7

In this tutorial, we will show you how to install and configuration of XCache on your CentOS 7 server. For those of you who didn’t know, XCache is an open-source opcode cacher, which means that it accelerates the performance of PHP on servers. It optimizes performance by removing the compilation time of PHP scripts by caching the compiled state of PHP scripts into the shm (RAM) and uses the compiled version straight from the RAM. This will increase the rate of page generation time by up to 5 times as it also optimizes many other aspects of PHP scripts and reduces server load.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple. I will show you through the step by step installation XCache in CentOS 7 server.
