linux mount/umount 挂载/卸载ISO镜像

虚拟机加载ISO镜像

在VMWare中的Linux虚拟机设置ISO镜像文件的路径，先完成设置，接着连接

mount挂载

先在/media目录下创建cdrom文件夹，用于统一的挂载ISO镜像文件，这样便于日常操作

[root@linux1 /]# cd /media
[root@linux1 media]# mkdir cdrom

linux光驱加载的文件路径默认是在/dev/cdrom目录下，但不能操作也不能像文件夹那样直接操作，所以用mount命令挂载到物理路径

[root@linux1 cdrom]# mount /dev/cdrom /media/cdrom/
mount: block device /dev/sr0 is write-protected, mounting read-only
[root@linux1 media]# ll cdrom/ #接下来就可以像普通文件夹一样操作ISO镜像中的文件夹了，但这只是只读的喔

配置简单的本地YUM源

baseurl：文件的路径；enabled：启用当前yum源；gpgcheck：gpg检查不启用

[root@linux1 ~]# cd /etc/yum.repos.d/
[root@linux1 yum.repos.d]# cat rhel6-iso.repo 
[rhel-source]
name=Red Hat Enterprise Linux 6 ISO
baseurl=file:///media/cdrom
enabled=1
gpgcheck=0

测试本地YUM源是否配置好了
