• 在 CentOS 9 Stream 系统中，管理软件镜像源主要通过修改/etc/yum.repos.d/目录下的配置文件来实现
  

一、 查看当前镜像源

• 列出所有可用的镜像源配置

ls /etc/yum.repos.d/

移动到当前镜像源

cd /etc/yum.repos.d

tree

• 常见的源文件有：CentOS-Stream-AppStream.repo、CentOS-Stream-BaseOS.repo 等。

• 查看某个源的具体内容

cat centos.repo

二、删除当前镜像源

• 首先我们需要备份一下我们的镜像源文件

sudo cp /etc/yum.repos.d/centos-addons.repo     /etc/yum.repos.d/centos-addons.repo.bak

sudo cp /etc/yum.repos.d/centos.repo     /etc/yum.repos.d/centos.repo.bak

• 然后执行删除镜像源代码
• 方法一：直接删除配置文件（不推荐，可能影响系统更新）

sudo rm /etc/yum.repos.d/centos-addons.repo
sudo rm /etc/yum.repos.d/centos.repo

• 方法二：注释掉配置文件中的 baseurl 和 mirrorlist 行

sudo sed -i 's/^baseurl=/#baseurl=/g' /etc/yum.repos.d/centos.repo

三、更新镜像源

• 首先创建镜像源的文件夹

sudo vim /etc/yum.repos.d/centos.repo

• 在里面添加下面的代码

[baseos]

• 国内阿里云镜像源

[baseos]
name=CentOS Stream \$releasever - BaseOS
mirrorlist=https://mirrors.aliyun.com/centos-stream/\$releasever/BaseOS/\$basearch/os/mirrorlist
gpgcheck=1
enabled=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-Official

• 清华大学镜像

[baseos]

• 华为云镜像

[baseos]
name=CentOS Stream \$releasever - BaseOS
mirrorlist=https://repo.huaweicloud.com/repository/conf/CentOS-Stream-Mirrors.repo?repo=\$releasever/BaseOS/\$basearch/os
gpgcheck=1

name=CentOS Stream \$releasever - AppStream
mirrorlist=https://repo.huaweicloud.com/repository/conf/CentOS-Stream-Mirrors.repo?repo=\$releasever/AppStream/\$basearch/os
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-Official

四、验证

• 首先清理缓存

sudo dnf clean all

• 验证镜像源是否生效

sudo dnf repolist -v
