[root@node6 yum.repos.d]# yum clean all

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:

2.7.8 (default, Sep  5 2016, 17:22:38) 

[GCC 4.4.7 20120313 (Red Hat 4.4.7-17)]

If you cannot solve this problem yourself, please go to 

the yum faq at:

[root@node6 yum.repos.d]#

大概是自定义安装python造成

[root@node6 yum.repos.d]# python

修改过来：

[root@node6 ~]# cd /usr/bin/

[root@node6 bin]# mv python.bak python

mv：是否覆盖"python"？ y

[root@node6 bin]# python

python         python2.6.bak  python2.bak    

[root@node6 bin]# python
