Can't run python 3.3.3 on CentOS nonGUI environment

Question

Well I have a question about running python 3.3.3 on CentOS. I installed using this guide: http://toomuchdata.com/2012/06/25/how-to-install-python-2-7-3-on-centos-6-2/. But instead of downloading 3.3.0 in downloaded 3.3.3 from this link: www.python.org/ftp/python/3.3.3/Python-3.3.3.tgz. So i used:

wget www.python.org/ftp/python/3.3.3/Python-3.3.3.tgz
tar xvzf file.tgz
cd Python-3.3.3
./configure --prefix=/usr/local
make && make altinstall

When I run python using command python I'm still in 2.6.6 (It was on CentOS already before) instead of 3.3.3. What did I do wrong?

Answer 1

You have to start python 3.x with

python3

Answer 2

What I've normally done with my production systems is put /usr/local/bin/ in the $PATH which is where I end up compiling Python (2.7 in my case) on CentOS systems.

Also remember that other versions of Python are normally "suffixed", so start it with:

$ python3.3

Answer 3

Try this method to install Python on Centos 7
