環境：Red Hat Enterprise Linux 5（rhel5.2_server-i386-dvd.iso）
虛擬機：Vmware7
YUM已安裝
目標：安裝gcc
配置：
1、掛載光盤（這裏面已經自動掛載了）
/dev/hdc on media/Rhel_5.2 i386 DVD/Server
2、創建鏈接
[root@localhost]#ln -s /dev/media/Rhel_5.2 i386 DVD/Server /Server
ln這是linux中一個非常重要命令。它的功能是爲某一個文件在另外一個位置建立一個同不的鏈接，這個命令最常用的參數是-s,具體用法是：ln -s 源文件 目標文件。用ls -l命令察看，就可以看到顯示的link的路徑了
3、修改yum.repos.d目錄下配置文件
[root@localhost ]# vi /etc/yum.repos.d/rhel-debuginfo.repo
[base]
name=Server
baseurl=file:///Server
enabled=1
gpgcheck=0
測試：
[root@localhost]#yum clean all // 清除 yum 緩存
[root@localhost]#yum list // 顯示所有可用的 rpm 包
[root@localhost]#yum grouplist // 顯示所有 yum 服務器定義的組
