CentOS 8.3 YUM Source

一、CentOS 8.3 YUM Source

YUM 源出错

[root@localhost ~]# uname -a

Error: Failed to download metadata for repo 'appstream': Cannot prepare internal mirrorlist: No URLs in mirrorlist

解决

如果仍然需要运行旧CentOS 8，可以在/etc/yum.repos中更新repos.d使用vault.centos.org代替mirror.centos.org

修改下面两个文件

cd /etc/yum.repos.d
vi CentOS-Linux-BaseOS.repo
vi CentOS-Linux-AppStream.repo

1 CentOS-Linux-BaseOS.repo 的内容修改为

[Baseos]
name=CentOS Linux $releasever - BaseOS
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=BaseOS&infra=$infra
#baseurl=http://mirror.centos.org/$contentdir/$releasever/BaseOS/$basearch/os/
baseurl=https://vault.centos.org/centos/$releasever/BaseOS/$basearch/os/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial

2 CentOS-Linux-AppStream.repo 的内容修改为

[appstream]
name=CentOS Linux $releasever - AppStream
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=AppStream&infra=$infra
#baseurl=http://mirror.centos.org/$contentdir/$releasever/AppStream/$basearch/os/
baseurl=https://vault.centos.org/centos/$releasever/AppStream/$basearch/os/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial

3 再执行

yum -y install epel-release
