【LINUX】 centos7下重装yum和python

因一些操作把yum和python全删除，重新安装

1、下载依赖

依赖套依赖，大家懂的，太恶心了，根据提示去下面地址下载即可http://mirrors.163.com/centos/7/os/x86_64/Packages/

执行：rpm -ivh python*rpm      

执行：rpm -ivh yum-*

报错，恶心的很，别着急，往下看。。。

2、下载并编译python2.7.5，不是重点，省略

rpm -Uvh --replacepkgs python*.rpm

 rpm -Uvh --replacepkgs rpm-python*.rpm yum*.rpm rpm-*
