Pre-Flight Check

  • I’ll be working from a Liquid Web Core Managed CentOS 7 server, and I’ll be logged in as non-root user. If you need more information then visit our tutorial on How to Add a User and Grant Root Privileges on CentOS 7.
Step #1: Add the EPEL Repository
Ansible is part of Extra Packages for Enterprise Linux (EPEL), which is a community repository of non-standard packages for the RHEL distribution. First, we need to install the EPEL repository. Directions on enabling EPEL can be found here.
Step #2: The Installation
As a matter of best practice we’ll update our packages: sudo yum -y update Then let’s install XCache and any required packages: sudo yum -y install php-xcache xcache-admin
Step #3: Verify the Extension is Available
Now verify that the extension is available by using the following command: php -m | grep XCache Your result should be: XCache XCache Cacher XCache Coverager XCache Optimizer XCache XCache Cacher XCache Coverager XCache Optimizer Listing the PHP version should now include information about XCache as well: php -v PHP 5.4.16 (cli) (built: Oct 31 2014 12:59:36) Copyright (c) 1997-2013 The PHP Group Zend Engine v2.4.0, Copyright (c) 1998-2013 Zend Technologies with XCache v3.1.1, Copyright (c) 2005-2014, by mOo with XCache Optimizer v3.1.1, Copyright (c) 2005-2014, by mOo with XCache Cacher v3.1.1, Copyright (c) 2005-2014, by mOo with XCache Coverager v3.1.1, Copyright (c) 2005-2014, by mOo
