Install pip on AWS EC2

While stock EC2 AMI comes with python installed, pip version is pretty old. Updating pip results in pip going out of path - it gets installed on a different location.

Here is sample script to update pip and still keep pip running:

#!/bin/bash
yum update -y
pip install -U pip
export PATH=$PATH:/usr/local/bin

Please make sure that it is run as root user only, otherwise it will error out with permission error
