What is the best way to install Python 2.7 on CentOS? All the tutorials I'm seeing are either using a third party management system or manually installing a separate binary to co-exist with Python 2.4. Why is 2.4 needed, and how can I seamlessly install 2.7?

I ended up going with Python 2.7 and took the following steps:

  1. Download the source
  2. Update gcc and other build tools.
  3. configure && make && make altinstall

For Django:

  1. Removed django from the original 2.4 site-packages directory.
  2. Reinstalled django using python2.7 setup.py install.

A longer and much more detailed version can be found here.

I had to add the following steps : echo /usr/local/lib >> /etc/ld.so.conf.d/usrlib.conf && ldconfig – yanjost May 20 '11 at 9:39
@yanjost: Where exactly did you have to add that step? – Josh K May 20 '11 at 11:03
after step 3, because libpython2.7.so could not be found – yanjost May 21 '11 at 14:38
@yanjost: Interesting, thanks! – Josh K May 21 '11 at 15:46

Python 2.4 incompatible with Pyhton 2.6. CentOS packages and a lot of core features depend on python.

how can I seamlessly install 2.6?

For (for x64 change i386 to x86_64):

rpm -ivh http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/i386/epel-release-1-1.ius.el5.noarch.rpm
rpm -ivh http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/i386/ius-release-1.0-6.ius.el5.noarch.rpm
yum clean all
yum install python26

Then disable epel and ius(set enabled=0 in /etc/yum.repos.d/ius.repo and /etc/yum.repos.d/epel.repo)
