[MM3-users]Request for assistance for fresh install of Mailman 3.0.3 and Python 3.4

Hello World! Very nice to meet you all this afternoon!

In order to avoid compatibility issues, I reinstalled CentOs 7. Firewalld, Apache and BIND are operational. I also installed Python 3.4 at http://www.codeghar.com/blog/install-latest-python-on-centos-7.html; however I understand that Python 2.7 is still available and am confused about usage of each version.

I downloaded the tarball for mailman 3.0.3. I will greatly appreciate if you quickly let me know how to install it. I do not wish to use mailman bundler.
