先将ISO文件挂载起来：

[root@racdb1 ~]# mount -o loop /opt/soft/rhel-server-6.8-x86_64-dvd.iso /mnt/iso

[root@racdb1 ~]# df| grep iso

/opt/soft/rhel-server-6.8-x86_64-dvd.iso

                         3787224    3787224          0 100% /mnt/iso

[root@racdb1 ~]# mount| grep iso

/opt/soft/rhel-server-6.8-x86_64-dvd.iso on /mnt/iso type iso9660 (rw,loop=/dev/loop0)

生成文件/etc/yum.repos.d/iso.repo，同目录的其它文件可以移动位置备份起来。

root@racdb1 yum.repos.d]# pwd

/etc/yum.repos.d

[root@racdb1 yum.repos.d]#

[root@racdb1 yum.repos.d]# cat iso.repo

[iso]

name=iso

baseurl=file:///mnt/iso

enabled=1

gpgcheck=0

[root@racdb1 yum.repos.d]#

然后初始化yum环境：

[root@racdb1 yum.repos.d]# yum clean all
