By default centos comes with python 2.6. In most of the cases we might need python 2.7 or later to be installed. Below are few ways to install python 2.7 on centos 6.x.

Method 1 - Using SCL (centos 6.5 and earlier)

First off, update the system to the latest state. Just in case there are any pending fixes.

yum -y update

Next install the SCL Softwate Collection repository for centos.

yum install centos-release-SCL 
yum install python27

Setting the default for the shell.

scl enable python27 bash

This will set all the path required.
