为新装的Linux系统配置国内yum源（阿里源）

news 2025/5/19 5:13:28

我安装的是Centos8，以此为例

1.先为原先的repo文件做备份

cd /etc/yum.repos.d/
sudo mkdir repo_backup
sudo mv *.repo repo_backup/  # 移动所有默认源文件至备份目录

2.从阿里网站拉取基础仓库配置文件


[root@192 yum.repos.d]# sudo wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-8.repo

结果展示

3.因为Centos8有点不一样，需要额外执行命令禁用无效的官方源

sudo sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*
sudo sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*

4.创建本地源配置文件（这个步骤我没有配好，可以不用这一步，使用默认的就行）

编辑或新建 /etc/yum.repos.d/local.repo：

[local-BaseOS]
name=CentOS-$releasever - BaseOS (Local)
baseurl=file:///media/cdrom/BaseOS
gpgcheck=0
enabled=0[local-AppStream]
name=CentOS-$releasever - AppStream (Local)
baseurl=file:///media/cdrom/AppStream
gpgcheck=0
enabled=0
