Installing OpenStack Keystone (Identity) Service | Part 1

Following my high level description of OpenStack, I now delve in the install of OpenStack This post is a manual install of OpenStack on Centos. Although the steps are detailed here:  http://docs.openstack.org/folsom/openstack-compute/install/yum/content/ my experience was that the output of each command results in text strings that are required in subsequent commands.
