RedHat8.0配置本地yum源

mount /dev/sr0 /mnt/

mount: /mnt: WARNING: device write-protected, mounted read-only.

cp -ra /mnt/media.repo /etc/yum.repos.d/

vim /etc/yum.repos.d/media.repo

[baseOS]
name=baseOS
baseurl=file:///mnt/baseOS
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
enabled=1

[AppStream]
name=AppStream
baseurl=file:///mnt/AppStream
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-beta

yum repolist查看是否成功（这个地方需注意的是AppStream 和 baseOS必须两个都成功，有一个没成功就连不上）
