Cannot find a valid baseurl for repo: base/7/x86_64 解决办法

一、检查网络连接

确保你的服务器可以访问互联网。你可以使用 ping 命令来测试：

ping www.baidu.com

若能访问外网，则网络没问题，否则检查网络

二、修改CentOS-Base.repo文件

执行：sudo vi /etc/yum.repos.d/CentOS-Base.repo

将文件内容修改为

# 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.

[base]

name=CentOS-$releasever - Base

#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra

baseurl=centos安装包下载_开源镜像站-阿里云http://mirrors.aliyun.com/centos/$releasever/os/$basearch/centos安装包下载_开源镜像站-阿里云

gpgcheck=1

gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7

#released updates

[updates]

name=CentOS-$releasever - Updates

#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates&infra=$infra

baseurl=http://mirrors.aliyun.com/centos/$releasever/updates/$basearch/

gpgcheck=1

gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7

#additional packages that may be useful

[extras]
name=CentOS-$releasever - Extras
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras&infra=$infra
baseurl=http://mirrors.aliyun.com/centos/$releasever/extras/$basearch/
gpgcheck=1
gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7

说明由于官方CentOS服务器可能不稳定或已停用，所以更换为更稳定的国内镜像源。通过替换/etc/yum. repos . d/Centos- Base. repo文件中的内容来实现这一点。
