12月后Centos 6 系统无法使用yum出现错误(文章底部看)
相信已经有一部分朋友今天连接到CentOS 6的服务器后执行yum后发现报错,那么发生了什么?
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。
一键修复

sed -i "s|enabled=1|enabled=0|g" /etc/yum/pluginconf.d/fastestmirror.conf
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
curl -k -o /etc/yum.repos.d/CentOS-Base.repo https://linux365.cn/yum/Centos-6-Vault-Aliyun.repo 
yum clean all
yum makecache

手动修复教程:
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

先把之前的repo挪到备份,然后下面两个二选一

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

替换为官方Vault源(海外服务器用)

curl -k -o /etc/yum.repos.d/CentOS-Base.repo https://linux365.cn/yum/Centos-6-Vault-Official.repo

或者替换为阿里云Vault镜像(国内服务器用)

curl -k -o /etc/yum.repos.d/CentOS-Base.repo https://linux365.cn/yum/Centos-6-Vault-Aliyun.repo
