We currently have a server running python2.6 + apache and mod_wsgi that runs with Django 1.3.
I plan to use the following guide to install python 2.7 http://toomuchdata.com/2012/06/25/how-to-install-python-2-7-3-on-centos-6-2/.
Then use pip to install the packages for 2.7 which I believe using pip install after installing python2.7 will handle this.
After this I think recompiling mod_wsgi with it pointing to the python2.7 path should handle making Apache2 load the correct version of python for the site.
I was just wondering if I have missed something or whether this process is completely wrong and shouldn't be used.
