CentOS 7/8误删python导致yum不可用的解决办法

解决Centos7、Centos8系统yum损坏,python损坏等导致的yum不可用问题。

前言

博主Centos系统为Centos8.5.2111版本,可能当时脑抽就以为自己的系统是Centos7版本,安装一个包怎么装不上,网上查阅资料各种折腾,发现yum被我搞坏了,最后又是各种折腾安装yum,特意记录下来。

解决办法

卸载和删除python、yum的残留文件,再下载自己系统版本对应的python、yum包进行安装。

具体步骤

删除python已安装程序及其关联

rpm -qa|grep python|xargs rpm -ev --allmatches --nodeps

删除残余python文件

whereis python |xargs rm -frv

验证删除,返回为无结果

whereis python

删除现有yum

rpm -qa|grep yum|xargs rpm -ev --allmatches --nodeps

删除残余yum文件

whereis yum |xargs rm -frv

查看版本号

Release:8.5.2111 为我自己的Centos版本,下载的包的版本应与系统版本号对应的一致。

更改系统版本号为你自己的版本号

创建目录python和yum用以存放rpm包

mkdir /usr/local/src/python
mkdir /usr/local/src/yum

下载python以及yum的rpm包

安装python以及yum的rpm包

#安装Python
cd /usr/local/src/python
#Centos7
rpm -ivh python-*   rpm-python-* --nodeps --force
#Centos8
rpm -ivh python3-* platform-python-* --nodeps --force
#安装yum
cd /usr/local/src/yum
rpm -ivh yum-*

大功告成!

没有成功的查看以下方法

rpm -ivh yum-*
#下载全量依赖包
repotrack yum
#安装
rpm -Uvh --force --nodeps *.rpm
