执行安装命令
#rpm -Uvh –replacepkgs lvm2-python-libs*.rpm –nodeps –force
#rpm -Uvh –replacepkgs libxml2-python*.rpm –nodeps –force
#rpm -Uvh –replacepkgs python*.rpm –nodeps –force
#rpm -Uvh –replacepkgs rpm-python*.rpm yum*.rpm –nodeps –force
如果将python换成python3的话，运行yum会报错
[root@iz2ze3ogy01eqvjs99e8nez python]# yum
File “/usr/bin/yum”, line 30
except KeyboardInterrupt, e:
^
SyntaxError: invalid syntax
修改 vi /etc/usr/yum 第一行为
#!/usr/bin/python2
