So What's XCache ? XCache is a powerfull PHP Accelerator (similar to APC, eAccelerator, etc). It's stable enough and really very fast.

Important: This tutorial assumes that you already have a running webserver (Apache) and PHP installed.

Let's install XCache. First of all I recommand doing a full upgrade of your system, for that do :

# apt-get update && apt-get dist-upgrade

Once that's done all we need to do is :

# apt-get install php5-xcache

That's it xcache is now installed. You might need to restart your apache server by doing :

# /etc/init.d/apache2 restart

After that you can check that xcache is running by checking the information returned by phpinfo().

That's that.
