# 前言 #

找了很多解决方案，基本都是说添加DNS或者修改ONBOOT值的，但是我依然不能成功，错误提示的最后一行都是一样的，希望和我初学遇到一样困难的朋友们能参考我的解决方案

--------------------

CentOS 6已经随着2020年11月的结束进入了EOL（Reaches End of Life），不过有一些老设备依然需要支持，CentOS官方也给这些还不想把CentOS 6扔进垃圾堆的用户保留了最后一个版本的镜像，只是这个镜像不会再有更新了

官方便在12月2日正式将CentOS 6相关的软件源移出了官方源，随之而来逐级镜像也会陆续将其删除。

不过有一些老设备依然需要维持在当前系统，CentOS官方也给这些还不想把CentOS 6扔进垃圾堆的用户保留了各个版本软件源的镜像，只是这个软件源不会再有更新了。

# 正题 #

## 1.首先把fastestmirrors关了 ##

#编辑
    vi /etc/yum/pluginconf.d/fastestmirror.conf
    #修改
    enable=0
    #或者执行以下命令
    sed -i "s|enabled=1|enabled=0|g" /etc/yum/pluginconf.d/fastestmirror.conf

## 2.先把之前的repo挪到备份 ##

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

## 3.替换为官方Vault源(海外服务器用) ##

curl -o /etc/yum.repos.d/CentOS-Base.repo https://www.xmpan.com/Centos-6-Vault-Official.repo

或者替换为阿里云Vault镜像(国内服务器用)

curl -o /etc/yum.repos.d/CentOS-Base.repo https://www.xmpan.com/Centos-6-Vault-Aliyun.repo

## 4.下面是报错详情 ##
