2018-10-29 Redhat 7使用安装光盘做yum源

首先用VMware12虚拟机，光驱载入redhat7安装光盘iso文件。

创建挂载点

[root@localhost ~]#mkdir /mnt/cdrom
[root@localhost ~]# mount -lv /dev/sr0 /mnt/cdrom
mount: /dev/sr0 is write-protected, mounting read-only
mount: /dev/sr0 mounted on /mnt/cdrom.
[root@localhost ~]# ls /mnt/cdrom
addons  images      Packages                 RPM-GPG-KEY-    redhat-release
EFI     isolinux    release-notes            TRANS.TBL
EULA    LiveOS      repodata
GPL     media.repo  RPM-GPG-KEY-redhat-beta

编辑yum配置文件

[root@localhost ~]# vim /etc/yum.repos.d/rhcsa.repo
[rhcsa]
name=rhcsa
baseurl=file:///mnt/cdrom
enable=1
gpgcheck=0

保存退出，然后yum clean all, yum makecache 就OK了

[root@localhost ~]# yum clean all

最后写入/etc/fstab 开机启动，增加一句

/dev/sr0 /mnt/cdrom iso9660 defaults 0 0 

或者直接

echo "/dev/sr0 /mnt/cdrom iso9660 defaults 0 0" >> /etc/fstab
