linux 配置本地光盘YUM源​​

1、挂载光盘到 /media下    

[root@localhost ~]#  mount /dev/cdrom /media

2、直接配置文件了。

gpgkey=file:///media/RPM-GPG-KEY-redhat-release 根据本机的文件名称设置

[root@localhost ~]#  cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# ls
redhat.repo   rhel-source.repo
[root@localhost yum.repos.d]touch rhel-media.repo
[root@localhost yum.repos.d]# vi rhel-media.repo
[media]
name=Red Hat Enterprise Linux 7.3                       
baseurl=file:///media                                      
enabled=1                                                        
gpgcheck=1                                                        
gpgkey=file:///media/RPM-GPG-KEY-redhat-release

3、清除原有缓存

[root@localhost ~]# yum clean all
……
Cleaning repos: media
Cleaning up Everything

4、获取yum列表

验证yum配置是否成功

[root@localhost ~]# yum makecache
……          
Metadata Cache Created
[root@localhost ~]#
