Upgrading to Python 2.7 on CentOS 6.5

Published / by tuxninja / 1 Comment on Upgrading to Python 2.7 on CentOS 6.5

Hey Folks,

The systems running Tuxlabs are currently running CentOS 6.5 to emulate a production RHEL like setup for an Openstack Cloud. Running an operating system this old has it’s drawbacks such as dependencies. I was recently installing a well know Python framework and ran into compatibility issues. The framework required Python 2.7 and CentOS 6.5 comes with 2.6. The below is a step by step procedure for how to upgrade to Python 2.7 on CentOS 6.5 if  you ever should need it. However, as a reminder run a newer OS when possible and for god sakes if you don’t need Redhat support, run Ubuntu.

Step one, we verify we are indeed running Python 2.6

Ok then, let’s upgrade Python to 2.7. First let’s update all of our system applications, just in case for version dependencies and it’s good for security etc.

Next, we have to install Develop Tools, it is a required dependency to install Python.

Additionally, we will need these…

Now, let’s install Python 2.7

It is important to use ‘altinstall’ otherwise you will end up with two different versions of Python on your filesystem, both named ‘python’.

You can verify the install like so

That’s it ! Enjoy.
