最近在使用centos8 yum安装文件时候报错 Couldn't resolve host name for http://mirrorlist.centos.org/?release=8-stream&arch=x86_64&repo=AppStream&infra=stock [Could not resolve host: mirrorlist.centos.org],切换到国阿里云yum镜像的方法
备份原始配置
cd /etc/yum.repos.d/ && mkdir backup && mv *repo backup/
更新阿里云的yum镜像
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-8.repo
sed -i -e "s|mirrors.cloud.aliyuncs.com|mirrors.aliyun.com|g" /etc/yum.repos.d/CentOS-*
sed -i -e "s|releasever|releasever-stream|g" /etc/yum.repos.d/CentOS-*
更新缓存
yum clean all
yum makecache
done 。合并在一起的脚本
cd /etc/yum.repos.d/ && mkdir backup && mv *repo backup/
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-8.repo
sed -i -e "s|mirrors.cloud.aliyuncs.com|mirrors.aliyun.com|g" /etc/yum.repos.d/CentOS-*
sed -i -e "s|releasever|releasever-stream|g" /etc/yum.repos.d/CentOS-*
yum clean all
yum makecache
