• 在 CentOS 9 Stream 系統中，管理軟件鏡像源主要通過修改/etc/yum.repos.d/目錄下的配置文件來實現
  

一、 查看當前鏡像源

• 列出所有可用的鏡像源配置

ls /etc/yum.repos.d/

移動到當前鏡像源

cd /etc/yum.repos.d

tree

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

• 查看某個源的具體內容

cat centos.repo

二、刪除當前鏡像源

• 首先我們需要備份一下我們的鏡像源文件

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

• 然后執行刪除鏡像源代碼
• 方法一：直接刪除配置文件（不推薦，可能影響系統更新）

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

• 方法二：注釋掉配置文件中的 baseurl 和 mirrorlist 行

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

三、更新鏡像源

• 首先創建鏡像源的文件夾

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

• 在里面添加下面的代碼

[baseos]
name=CentOS Stream $releasever - BaseOS
metalink=https://mirrors.centos.org/metalink?repo=centos-baseos-$stream&arch=$basearch&protocol=https,http

• 國內阿里云鏡像源

[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[appstream]
name=CentOS Stream \$releasever - AppStream
mirrorlist=https://mirrors.aliyun.com/centos-stream/\$releasever/AppStream/\$basearch/os/mirrorlist
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-Official

• 清華大學鏡像

[baseos]
name=CentOS Stream \$releasever - BaseOS
mirrorlist=https://mirrors.tuna.tsinghua.edu.cn/centos-stream/\$releasever/BaseOS/\$basearch/os/mirrorlist
gpgcheck=1

gpgcheck=1

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

• 華為云鏡像

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

• 首先清理緩存

sudo dnf clean all

• 驗證鏡像源是否生效

sudo dnf repolist -v
