一、CentOS6停止维护更新日期2020年11月30日

二、2020年12月2日下架了包括官方所有的CentOS6源（包括国内的镜像站）

三、CentOS6也完成了它的历史使命

在生产的环境中依旧由很多CentOS6系统依然在坚持，那么可以采取挂载光盘或者使用centos-vault源安装软件包，这里挂载光盘的方式不做讲述。1

四、使用centos-vault作为更新源

1.官方地址

#阿里云http://mirrors.aliyun.com/centos-vault/#官方https://vault.centos.org/#阿里云和官方的任选其一即可1234567

2.使用阿里云centos-vault源

3.使用官方centos-vault源

4.替换CentOS-Base.repo文件内容后清除下缓存

yum clean all && yum makecache1

五、那么如何使用epel源

1.官方地址

https://archives.fedoraproject.org/pub/archive/epel/1

2.下载安装epel源

#下载epel源wget https://archives.fedoraproject.org/pub/archive/epel/6/x86_64/epel-release-6-8.noarch.rpm#安装epel源rpm -ivh epel-release-6-8.noarch.rpm#清除下缓存yum clean all && yum makecache
