Here is a quick tutorial where I install Apache 2.4 and PHP-FPM 5.6 into the virtual machine that I used in the previous related article called "Speeding up Drupal 7 on Centos 6 with Memcache APC and some modules". You should watch the video to get the full details of what I am doing, because this page is just mainly here to hold the commands that I will be using.
