centos6 yum源失效解决方法

今天看到服务器提示有漏洞需要更新，在执行更新命令的时候一直报错，因为CentOS 6操作系统版本结束了生命周期（EOL），Linux社区已不再维护该操作系统版本。导致不能正常更新，接下来吾爱编程为大家介绍一下Centos6 yum源失效解决方法，有需要的小伙伴可以参考一下：

1、背景信息：

2020年12月2日起，centos官方停止了对centos6的所有更新并且下架了包括官方所有的centos6源，目前阿里、163、清华等centos6源已无法使用。

如果非要用centos6的话就只能使用vault源，国内的vault源的话:

https://mirrors.tuna.tsinghua.edu.cn/centos-vault/、http://mirrors.aliyun.com/centos-vault/

2、解决方法：

  2.1备份文件

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

 2.2更改CentOS-Base.repo文件

vim /etc/yum.repos.d/CentOS-Base.repo 

 更改内容如下

[base]
name=CentOS-$releasever
enabled=1
failovermethod=priority
baseurl=http://mirrors.aliyun.com/centos-vault/centos/$releasever/os/$basearch/
gpgcheck=1

[updates]

gpgkey=http://mirrors.aliyun.com/centos-vault/centos/RPM-GPG-KEY-CentOS-6

  2.2更改epel.repo文件

vim /etc/yum.repos.d/epel.repo

更改内容如下

[epel]
name=Extra Packages for Enterprise Linux 6 - $basearch
baseurl=http://mirrors.aliyun.com/epel-archive/6/$basearch
failovermethod=priority
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
