错误处理
描述：执行yum出错(更新python版本和yum冲突)
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:
2.7.14 (default, Nov 27 2017, 21:30:20)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-18)]
If you cannot solve this problem yourself, please go to
the yum faq at:
http://yum.baseurl.org/wiki/Faq
原因: 之前yum是用python2.6版本的，所以yum的命令脚本里面指定回2.6版本的python即可
解决如下:(声明指定：/usr/bin/python.2.6.6)
# which yum
/usr/bin/yum
# cat /usr/bin/yum | head -5
#!/usr/bin/python.2.6.6
import sys
try:
import yum
except ImportError:
