2024年最新：配置CentOS 7阿里yum源

2024-9-20

前言

根据CentOS官方声明，CentOS 7的支持已于2024年6月30日正式终止，伴随而来的是软件仓库从上游的移除。

国内镜像站如阿里云、TUNA等已同步下架了CentOS 7（涵盖el7、rhel7及centos7等版本）的软件包，导致多数现有YUM源配置教程失效。

尽管如此，这些镜像站为维持用户过渡，提供了CentOS 7等停服版本的历史归档服务，允许继续使用该系统的用户切换至相应的归档YUM源以维持操作。

一、备份yum源配置文件

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

二、新建阿里云YUM源配置文件

下面将以CentOS 7.9为例配置阿里云yum源，其他版本的CentOS 7可以将配置文件中的7.9.2009全部替换为你使用的系统版本，如：7.8.2003、7.7.1908等

新建yum仓库配置文件

vi /etc/yum.repos.d/CentOS-Base.repo

点击i键进入编辑模式，将以下配置信息复制到配置文件中

# 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-$releasever - Base - mirrors.aliyun.comfailovermethod=prioritybaseurl=https://mirrors.aliyun.com/centos-vault/7.9.2009/os/$basearch/gpgcheck=1gpgkey=https://mirrors.aliyun.com/centos-vault/RPM-GPG-KEY-CentOS-7
