一、删除所有Python
[root@test ~]# rpm -qa|grep python|xargs rpm -ev --allmatches --nodeps ##强制删除已安装程序及其关联
[root@test ~]# whereis python |xargs rm -frv ##删除所有残余文件 ##xargs,允许你对输出执行其他某些命令
[root@test ~]# whereis python ##验证删除,返回无结果
二、删除现有的YUM
[root@test ~]# rpm -qa|grep yum|xargs rpm -ev --allmatches --nodeps
[root@test ~]# whereis yum |xargs rm -frv

四、安装
由于安装过程中,多个包存在相互依赖的关系,所有这里一起安装。
[root@test ~]# rpm -Uvh --replacepkgs python*.rpm
[root@test ~]# rpm -Uvh --replacepkgs rpm-*.rpm yum*.rpm zlib-*.rpm libxml2-*.rpm
五、测试
[root@test ~]# python
Python 2.6.6 (r266:84292, Aug 18 2016, 15:13:37)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-17)] on linux2
