• These instructions are intended specifically for installing XCache, an open-source opcode cacher, on Ubuntu 12.04 LTS.
• I’ll be working from a Liquid Web Core Managed Ubuntu 12.04 LTS server with Apache and PHP installed, 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 Ubuntu 12.04 LTS.

As a matter of best practice we’ll update our packages:

sudo apt-get update

Then let’s install XCache and any required packages:

sudo apt-get install php5-xcache

Now verify that the extension is available by using the following command:

php -m | grep XCache

Your result should be:

XCache
XCache

Listing the PHP version should now include information about XCache as well:

php -v
