1.挂载光盘
[root@localhost ~]# mount /dev/cdrom /media/cdrom/ mount: /dev/sr0 写保护,将以只读方式挂载
/media下的cdrom目录是事先创建好的
2.修改yum配置文件(文件位置:/etc/yum.repos.d)
[root@localhost /]# cd /etc/yum.repos.d/ [root@localhost yum.repos.d]# mkdir bak #创建一个文件夹来存放多余的配置文件 [root@localhost yum.repos.d]# mv *.* bak/ [root@localhost yum.repos.d]# cd bak/ [root@localhost bak]# ls CentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo CentOS-CR.repo CentOS-fasttrack.repo CentOS-Sources.repo [root@localhost bak]# mv CentOS-Media.repo ../ [root@localhost bak]# cd ../ [root@localhost yum.repos.d]# vi CentOS-Media.repo
# CentOS-Media.repo # # This repo can be used with mounted DVD media, verify the mount point for # CentOS-7. You can use this repo and yum to install items directly off the # DVD ISO that we release. # # To use this repo, put in your DVD and use it with the other repos too: # yum --enablerepo=c7-media [command] # # or for ONLY the media repo, do this: # # yum --disablerepo=* --enablerepo=c7-media [command] [c7-media] name=CentOS-$releasever - Media baseurl=file:///media/CentOS/ file:///media/cdrom/ #本地yum源所在路径 file:///media/cdrecorder/ gpgcheck=0 #这里为0不进行检查 enabled=1 #这里为1 启动 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 ~
保存退出
3.验证
我们使用 yum 命令加上 list 参数就可以查看仓库
[root@localhost /]# yum list
