查看python的版本

shell> python -V
Python 2.6.6

安装Python

shell> tar zxvf Python-2.7.9.tgz 
shell> cd Python-2.7.9

建立新的安装路径python,而是安装路径
shell> mkdir -p /usr/local/python
shell> ./configure --prefix=/usr/local/python
shell> make && make install

python多版本共存解决

shell> mv /usr/bin/python /usr/bin/python_old
shell> ln -s /usr/local/python/bin/python /usr/bin/python
shell> python -V
Python 2.7.9
shell> python_old -V
Python 2.6.6

解决yum的python版本问题

shell> yum
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

   No module named yum

Please install a package which provides this module, or
verify that the module is installed correctly.

It's possible that the above module doesn't match the
current version of Python, which is:
2.7.9 (default, Feb 10 2015, 22:36:03) 
[GCC 4.4.6 20110731 (Red Hat 4.4.6-3)]

If you cannot solve this problem yourself, please go to 
the yum faq at:
  http://yum.baseurl.org/wiki/Faq

shell> vim /usr/bin/yum
============================================================
#!/usr/bin/python替换为
#!/usr/bin/python_old
============================================================
