常规

老vps重装centos8 后
Couldn’t resolve host name for http://mirrorlist.centos.org/?release=8-stream

处理：
sed -i s/mirror.centos.org/vault.centos.org/g /etc/yum.repos.d/.repo
sed -i s/^#.baseurl=http/baseurl=http/g /etc/yum.repos.d/.repo
sed -i s/^mirrorlist=http/#mirrorlist=http/g /etc/yum.repos.d/.repo

yum clean all
yum install epel-release

参考： CentOS 7镜像列表服务下线，还想继续使用该怎么办？ - 知乎 (zhihu.com)
