CentOS 6的服务器后执行yum后发现出现Error: Cannot find a valid baseurl for repo: base解决办法

原因是CentOS 6已经随着2020年11月的结束进入了EOL（Reaches End of Life），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。

CentOS官方Vault源：http://vault./

 

首先把fastestmirror关了，这个插件默认会寻找离你最近的镜像站去访问：

vi /etc/yum/pluginconf.d/fastestmirror.conf

修改这个参数enable=0

备份CentOS6系统源

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

将下面的内容复制进去 vi /etc/yum.repos.d/CentOS-Base.repo

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.

更换源后尝试yum update，能够正常获取软件列表即可。
