OEL7.6设置光盘YUM源

先把原来的yum源改名让他失效

mv public-yum-ol7.repo public-yum-ol7.repo.bak

然后新建个yum源

[root@localhost yum.repos.d]# cat oel-media.repo 
[oel7.6-media]
name=Oracle Linux $releasever Latest ($basearch)
baseurl=file:///mnt/cdrom
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
[root@localhost yum.repos.d]#

然后重刷yum缓存即可 yum clean all yum makecache
