折腾着搞 openvpn 网站服务器 yum指令 出了点问题
------------------------------------------------------------
[root@cloud ~]# 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:
2.6.6 (r266:84292, Feb 22 2013, 00:00:18)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-3)]
-----------------------------------------------------------
原因：
根据报错信息提示，yum 会用到 Python 的某些模块。当前模块安装错误 或者 Python 版本错误
当前错误是 Python 版本错误
解决：
1. 查看yum版本 rpm -qa |grep yum
查看python版本 whereis python
发现 python果然安装了两个版本2.6和2.7版本
2. 编辑 yum 使用的 python 版本
vi /usr/bin/yum
把#!/usr/bin/python改为#!/usr/bin/python2.6
