Installing RabbitMQ on CentOS 6.3 Minimal

This tutorial will demonstrate how to install RabbitMQ 3.x on CentOS 6.3 ("minimal" profile).

This install was performed using VMWare Fusion on OSX, but should demonstrate the process on most environments using Linux-supported drivers. The virtual was 1-core, 1.6GB RAM, 6GB HDD space; I did not use the quick setup VMWare offers.

There are two ways of installing RabbitMQ on CentOS. The ways differ based on which distribution of Erlang you chose to use (the one out of EPEL or a later version from Erlang Solutions). We will demonstrate both ways in this example.

One of the goals of this tutorial is to not install anymore software than needed. We will use "vi" instead of "pico" or "nano" because that's what's bundled with CentOS minimal profile. If you would rather use another text editor, please install it on your own.
