CentOS误删python环境后怎么办？

Linux自带python2相关依赖，由于安装python3,怕会产生版本冲突，索性头脑一热，就把python2相关依赖包给删掉了，最后执行yum命令就出现下面这个错误

yum命令在linux还是经常有使用的，现在突然不能够使用，得想办法解决才行，经过百度相关经验贴，总结出以下解决办法。

1、查看Linux系统版本

 cat /etc/redhat-release

通过命令，我们得知我使用的Linux版本是 ：7.5.1804

2、下载相关依赖

首先新建一个目录，放我们接下来需要下载的yum和python相关依赖包

#创建目录并进入
mkdir python_and_yum && cd $_

2.1、下载依赖

2.2、安装依赖

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
