阿里云CentOS Linux 8 - AppStream使用yum安装nfs-utils失败

报错1

Status code: 404 for http://mirrors.cloud.aliyuncs.com/centos/8/AppStream/x86_64/os/repodata/repomd.xml

 

解决

cd /etc/yum.repos.d/

for i in `ls`;do sed -i 's/mirrors.cloud.aliyuncs.com/mirrors.aliyun.com/g' $i;done

for i in `ls`;do sed -i 's/$releasever/$releasever-stream/g' $i;done

 

报错2

Status code: 404 for https://mirrors.fedoraproject.org/metalink?repo=epel-modular-8-stream&arch=x86_64&infra=stock&content=centos

 

解决

vim /etc/yum.repos.d/epel-modular.repo

注释这行（[epel-modular]里的）
metalink=https://mirrors.fedoraproject.org/metalink?repo=epel-modular-$releasever&arch=$basearch&infra=$infra&content=$contentdir

增加这行
baseurl=http://mirrors.cloud.aliyuncs.com/epel/8/Everything/$basearch

 

最后再安装。
