How to install php 5.2 and php 5.3 in ubuntu 12.04 c ispmanager?

Question

PHP

Good afternoon, I need instructions on how to install php 5.2 on Ubuntu 12.04.
OS: Ubuntu server 12.04 LTS
PHP Version 5.3.10
Ispmager4 pro panel is installed.
They need to work at the same time. I have read on the forums.
I found instructions habrahabr.ru/post/176147
but I can't figure it out . My directory was not created. "/usr/bin/php52"

The easiest option is to raise Docker and two containers - in one 5.2 in the other 5.3, then we will leave behind the scenes that these are ancient versions and they are full of holes by default and open to any attacks from the outside.
