Centos6 yum源配置（CentOS 6停止更新）

一、背景

CentOS 6于2020年11月30日停止了官方支持，这意味着不再提供安全更新和错误修复。在停止支持后，CentOS 6的yum源也不再维护，因此无法使用官方的CentOS 6 yum源来安装软件包或更新系统。

二、解决方案

2.1 系统基本yum源

可以使用以下yum源代替
CentOS官方：http://vault.centos.org/
阿里云镜像：http://mirrors.aliyun.com/centos-vault/

关闭fastestmirror
[root@localhost ~]# vi /etc/yum/pluginconf.d/fastestmirror.conf

[main]
enabled=0 #修改为0
verbose=0

[root@localhost ~]# mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak
#替换为官方Vault源
wget -O /etc/yum.repos.d/CentOS-Base.repo https://static.lty.fun/%E5%85%B6%E4%BB%96%E8%B5%84%E6%BA%90/SourcesList/Centos-6-Vault-Official.repo

#替换为阿里云Vault镜像
wget -O /etc/yum.repos.d/CentOS-Base.repo https://static.lty.fun/%E5%85%B6%E4%BB%96%E8%B5%84%E6%BA%90/SourcesList/Centos-6-Vault-Aliyun.repo
#没装wget可复制源文件

2.2 EPEL的yum源

cat epel.repo
