--1、掛載本地iso檔案到/mnt/cdrom,如果沒有該目錄建立一下
mount -o loop /soft/rhel-server-6.4-x86_64-dvd.iso /mnt/cdrom


--2、新建repo檔案引數如下：
[[email protected] ~]# cd /etc/yum.repos.d/
[[email protected] yum.repos.d]# more public-yum-el5.repo 
[rhel6]
name = RHEL6.4
baseurl=file:///mnt/cdrom/Server/
gpgcheck=0
enabled=1


--3、儲存退出，測試yum是否ok，如果如下所示，說明已配好，可以使用yum命令安裝包了
