2024年最新：配置CentOS 7阿里yum源

前言

根据 CentOS 官方公告，CentOS 7 已经于 2024 年 6 月 30 日结束支持，其软件仓库也相应被上游移除。

阿里云、TUNA等国内镜像站也都移除了各类软件为 CentOS 7（包括 el7, rhel7 或 centos7 等多种变体）提供的版本，因此网上很多设置CentOS 7 YUM源的教程已经不再适用。

不过阿里云、TUNA等国内镜像站也为CentOS 7等官方不再支持的版本提供了历史归档，还在使用CentOS 7的用户可以切换到对应的归档YUM源。

一、备份yum源配置文件

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

复制代码

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

1. vi /etc/yum.repos.d/CentOS-Base.repo

复制代码

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

1. # CentOS-Base.repo
2. #
3. # The mirror system uses the connecting IP address of the client and the
4. # update status of each mirror to pick mirrors that are updated to and
5. # geographically close to the client. You should use this for CentOS updates
6. # unless you are manually picking other mirrors.
7. #
8. # If the mirrorlist= does not work for you, as a fall back you can try the
9. # remarked out baseurl= line instead.
10. #
11. #
13. [base]

39. failovermethod=priority

41. gpgcheck=1
42. enabled=0
43. gpgkey=https://mirrors.aliyun.com/centos-vault/RPM-GPG-KEY-CentOS-7
45. #contrib - packages by Centos Users

48. failovermethod=priority
49. baseurl=https://mirrors.aliyun.com/centos-vault/7.9.2009/contrib/$basearch/
50. gpgcheck=1
51. enabled=0
52. gpgkey=https://mirrors.aliyun.com/centos-vault/RPM-GPG-KEY-CentOS-7

复制代码

点击Esc键退出编辑模式，输入:wq保存配置文件

三、清除缓存并重建元数据缓存

1. yum clean all && yum makecache

复制代码

至此阿里云YUM源已经切换成功，可以尽情使用了
