CentOS7系统配置国内yum源和epel源

简介: 1.首先进入/etc/yum.repos.d/目录下,新建一个repo_bak目录,用于保存系统中原来的repo文件[root@bogon ~]# cd /etc/yum.repos.d/[root@bogon yum.

1.首先进入/etc/yum.repos.d/目录下,新建一个repo_bak目录,用于保存系统中原来的repo文件

[root@bogon ~]# cd /etc/yum.repos.d/

[root@bogon yum.repos.d]# mkdir repo_bak

[root@bogon yum.repos.d]# mv *.repo repo_bak/

2.在CentOS中配置使用网易和阿里的开源镜像

到网易和阿里开源镜像站点下载系统对应版本的repo文件

[root@bogon yum.repos.d]# wget http://mirrors.aliyun.com/repo/Centos-7.repo

[root@bogon yum.repos.d]# wget http://mirrors.163.com/.help/CentOS7-Base-163.repo

[root@bogon yum.repos.d]# ls
Centos-7.repo  CentOS-Base-163.repo  repo.bak

或者手动下载repo文件并上传到/etc/yum.repos.d/目录

网易开源镜像站

阿里开源镜像站

3.清除系统yum缓存并生成新的yum缓存

[root@bogon yum.repos.d]# ls        # 列出/etc/yum.repos.d/目录下的文件
Centos-7.repo  CentOS-Base-163.repo  repo.bak

[root@bogon yum.repos.d]# yum clean all     # 清除系统所有的yum缓存

解决 CentOS 7 官方 yum 仓库无法使用的最佳实践
【8月更文挑战第18天】若 CentOS 7 的官方 YUM 仓库无法使用,可按以下步骤解决: 1. **检查网络连接**: - 确认服务器能正常上网,可通过访问外部网站或网络诊断测试。 - 检查防火墙设置,避免其阻挡 YUM 的网络访问。 2. **检查 YUM 配置**: - 核实 `/etc/yum.repos.d/` 下的 `CentOS-Base.repo` 文件中仓库地址正确无误。 - 确认配置文件内的 `enabled` 选项设为 `1` 以启用仓库。
