Method 2: Another installation method

1. Download the python installation package from the official website.

The latest python version 3.2.2: Python-3.2.2.tgz is downloaded here

After the download, the file directory is under/home/python/, which is also the installation directory of my python

2. Decompress the package:

[Root @ www python] # tar zxvf Python-3.2.2.tgz

3. Open the installation directory and execute:

[Root @ www python] # cd Python-3.2.2.

[Root @ www Python-3.2.2] #./configure

[Root @ www Python-3.2.2] # make

[Root @ www Python-3.2.2] # makeinstall

The installation is complete.

4. If you enter the "python" command, the system still displays the old version. Therefore, you need to create a soft connection:

[Root @ www bin] # cd/usr/bin

[Root @ www bin] # ll | grep python

[Root @ www bin] # rm-rf python

[Root @ www bin] # ln-s/home/python/Python-3.2.2/python

[Root @ www bin] # python
