一、错误重现

CentOS Stream 8 - AppStream 0.0 B/s | 0 B 00:00
Errors during downloading metadata for repository 'appstream':
- Curl error (6): 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]
错误：为仓库 'appstream' 下载元数据失败 : Cannot prepare internal mirrorlist: Curl error (6): 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]

或者

Failed to set locale, defaulting to C.UTF-8
CentOS Linux 8 - AppStream 0.0 B/s | 0 B 00:00
Errors during downloading metadata for repository 'appstream':
- Curl error (6): Couldn't resolve host name for http://mirrorlist.centos.org/?release=8&arch=x86_64&repo=AppStream&infra=container [Could not resolve host: mirrorlist.centos.org]
Error: Failed to download metadata for repo 'appstream': Cannot prepare internal mirrorlist: Curl error (6): Couldn't resolve host name for http://mirrorlist.centos.org/?release=8&arch=x86_64&repo=AppStream&infra=container [Could not resolve host: mirrorlist.centos.org]

原因： CentOS Linux 8已于 2021年12月31日停止更新和维护，由于CentOS 团队从官方镜像中移除CentOS 8的所有包，所以在使用yum源安装或更新会报上述失败错误。

进入仓库源文件夹下

cd /etc/yum.repos.d/

修改镜像配置内容

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

清空原有缓存，并重新生成
