CentOS 7 停止维护后更换 YUM 源教程

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

常见问题解决

1. 更换源后仍无法安装更新：检查 YUM 源是否配置正确，并确保执行了 `yum clean all` 和 `yum makecache`。

yum clean all
yum makecache

2. YUM 源速度慢：可以尝试切换到离自己服务器更近的镜像源，或者使用 CDN 支持的源。

总结

CentOS 7 停止维护后，及时更换 YUM 源可以保证系统持续获得安全和软件包更新。建议用户尽量选择国内镜像源，以保证更好的速度和稳定性。同时，也可以考虑升级到 CentOS Stream 或其他受支持的发行版，如 Rocky Linux 或 AlmaLinux，以获得长期的安全和功能支持。
