前言

由于CentOS 7 官方已于2024年6月30日停止维护，这意味着不再有安全更新和功能更新，因此，继续使用 CentOS 7 的用户需要切换到社区或第三方提供的 YUM 源，以获得必要的更新和软件包支持，本文将介绍如何在 CentOS 7 停止维护后更换 YUM 源。

注意：本文仅适用于Centos7系统，请勿将本文用于其它版本系统！

部署教程

备份现有yum源

1. 进入 /etc/yum.repos.d/ 目录

cd /etc/yum.repos.d/

2. 备份现有的yum源文件

mkdir backup
mv *.repo backup/

我在这里整理了多个Centos7国内镜像的源，任选其一即可，在Centos7停服后，默认的源已从centos改成了centos-vault，这里所有的源都是我二次配置修改过的

更换yum源（x86_64架构）

阿里云源（curl方式）

curl -o /etc/yum.repos.d/Centos7-aliyun.repo https://mirrors.wlnmp.com/centos/Centos7-aliyun-x86_64.repo

阿里云源（wget方式）

wget https://mirrors.wlnmp.com/centos/Centos7-aliyun-x86_64.repo -P /etc/yum.repos.d/

网易源（curl方式）

curl -o /etc/yum.repos.d/Centos7-163.repo https://mirrors.wlnmp.com/centos/Centos7-163-x86_64.repo

网易源（wget方式）

wget https://mirrors.wlnmp.com/centos/Centos7-163-x86_64.repo -P /etc/yum.repos.d/

腾讯源（curl方式）

curl -o /etc/yum.repos.d/Centos7-tencent.repo https://mirrors.wlnmp.com/centos/Centos7-tencent-x86_64.repo

腾讯源（wget方式）

wget https://mirrors.wlnmp.com/centos/Centos7-tencent-x86_64.repo -P /etc/yum.repos.d/

中国科学技术大学源（curl方式）

curl -o /etc/yum.repos.d/Centos7-ustc.repo https://mirrors.wlnmp.com/centos/Centos7-ustc-x86_64.repo

中国科学技术大学源（wget方式）

wget https://mirrors.wlnmp.com/centos/Centos7-ustc-x86_64.repo -P /etc/yum.repos.d/

清华源（curl方式）

curl -o /etc/yum.repos.d/Centos7-tuna.repo https://mirrors.wlnmp.com/centos/Centos7-tuna-x86_64.repo

清华源（wget方式）

wget https://mirrors.wlnmp.com/centos/Centos7-tuna-x86_64.repo -P /etc/yum.repos.d/

更换yum源（只要当前不是x86_64架构的，都使用以下配置，适用于aarch64、i386、ppc64等）
