巨坑,切忌不要轻易删除Linux系统自带版本的Python

1.卸载python(防止未卸载干净)

rpm -qa|grep python|xargs rpm -ev --allmatches --nodeps #强制删除已安装程序及其关联
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

2.卸载yum

rpm -qa|grep yum|xargs rpm -ev --allmatches --nodeps
rm -rf /etc/yum.repos.d/*
whereis yum|xargs rm -frv

3.验证是否删除干净

whereis python #验证删除,应该是没有结果返回
whereis yum

4.安装python和yum

软件下载地址(我这里系统是centos 7.5.1804)
查看linux系统版本:cat /etc/redhat-release
http://vault.centos.org/7.5.1804/os/x86_64/Packages/
所需文件如下:(下载自己系统对应版本的就好)

5.上传并安装

我这里是或取链接后直接wget到一个目录中的,直接进入目录执行一下命令即可


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

安装成功后执行
