#升级版本

#解决Python升级yum无法使用的办法
[root@localhost yum.repos.d]# yum repolist 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: 2.7.6 (default, Jul 7 2016, 15:02:52) [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: http://yum.baseurl.org/wiki/Faq
#查看Python版本
[root@localhost init.d]# whereis python python: /usr/bin/python2.6-config /usr/bin/python.bak /usr/bin/python /usr/bin/python2.6 /usr/lib/python2.6 /usr/lib64/python2.6 /usr/include/python2.6 /usr/local/python2.7 /usr/share/man/man1/python.1.gz
#配置yum使用回低版本的python
[root@localhost init.d]# head -1 /usr/bin/yum #!/usr/bin/python2.6
#yum正常了
[root@localhost init.d]# yum repolist Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile repo id repo name status base CentOS-6 - Base - 163.com 6,696 extras CentOS-6 - Extras - 163.com 62 updates CentOS-6 - Updates - 163.com 139 repolist: 6,897
因为Yum是基于Python写的，升级了Python版本，Yum就调用了高版本的Python，所以报错
