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:
2.7.3 (default, Dec 17 2013, 17:33:06)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-54)]
If you cannot solve this problem yourself, please go to
the yum faq at: http://wiki.linux.duke.edu/YumFaq[/code]三、修改yum配置文件 
[root@a2 Python-2.7.3]# vim /usr/bin/yum
将“#!/usr/bin/python”改为“#!/usr/bin/python2.4”
[root@a2 Python-2.7.3]# yum clean all
