Centos upgrade to python3.3.2

1. Cenots6.3 is installed with 2.6.6 by default. to update and upgrade, you must install gcc:

Yum-y install gcc

The system automatically downloads and installs gcc.

2. Download python 3.3.2 http://python.org/getit/

3. Decompress python 3.3.2

Tar-jxvf Python-3.3.2.tar.bz2

4. Go to the directory: cd Python-3.3.2.tar.bz2

Install python

./Configure

Make all

Make install

Now we have installed python, but after entering the shell, check the python version: python-V and find that python is 2.6.6. We need to establish a link.

5. Establish a soft connection to allow the system to use the new version of python by default,

Mv/usr/bin/python/usr/bin/python2.6

Ln-s/usr/local/bin/python3.3/usr/bin/python

Verify whether python points to the following:

Python-V

After pointing the default python to 3.3.2, yum cannot be used normally. Edit the yum configuration file:

Vi/usr/bin/yum

#! /Usr/bin/python #! /Usr/bin/python2.6 save and exit.

For earlier centos versions, modify it #! /Usr/bin/python2.4
