nice work on this installation script.

Thanks, just out of curiosity why isn't possible to update to this version directly using a simple yum command with the default CentOS repositories?

Also your fork of this script failed for me due to the URLs used in the wget commands. I noticed several forks of your fork updated the problem paths with:

wget --no-check-certificate https://bootstrap.pypa.io/ez_setup.py
wget --no-check-certificate https://bootstrap.pypa.io/get-pip.py

Maybe you can update yours since it's the top google hit to save the next guy some time?

And on a final note, I needed to use the "force" flag to ln here: ln -sf /usr/local/bin/pip /usr/bin/pip as I had existing symlink there for pip.

To anyone running this I suggest this execution to capture what happens and to abort on first failure:

bash -x -e install_python.sh 2>&1 | tee install_python.log

zlib-dev should be zlib-devel

get-pip.py change to https://bootstrap.pypa.io/get-pip.py

Thanks for this, slightly modified version which worked for me

bash -x -e ./python2.7.sh 2>&1 | tee install_python.log

cat ./python2.7.sh

Easy to copy @michalpirgl version.

It worked fine for me while the others failed 👍

reboot may be needed

python --version
