VirtualBox下RedHat 5.4 使用DVD光盤作為yum源

1、首先掛載光盤

設備-分配光驅-Choose a virtual CD/DVD disk file 選擇DVD鏡像，此時鏡像被自動加載到

/media/RHEL_5.4 x86_64 DVD

2、新建/etc/yum.repos.d/dvd.repo，添加如下內容並保存

[base]
name=Server
baseurl=file:///media/RHEL_5.4%20x86_64%20DVD/Server

enable=1
gpcheck=1
gpgkey=file:///media/RHEL_5.4%20x86_64%20DVD/RPM-GPG-KEY-RedHat-release

注：由於文件路徑中有空格，所以需要將其轉義成%20

如果還需要安裝關於cluster、clusterstorage或者xen相關的軟件包，只須再添加以下內容：
[VT]
name=VT

baseurl=file:///media/RHEL_5.4%20x86_64%20DVD/VT
enable=1
gpcheck=1
gpgkey=file:///media/RHEL_5.4%20x86_64%20DVD/RPM-GPG-KEY-redhat-release
[Cluster]
name=Cluster

baseurl=file:///media/RHEL_5.4%20x86_64%20DVD/Cluster
enable=1
gpcheck=1
gpgkey=file:///media/RHEL_5.4%20x86_64%20DVD/RPM-GPG-KEY-redhat-release
[CS]
name=ClusterStorage

baseurl=file:///media/RHEL_5.4%20x86_64%20DVD/ClusterStorage
enable=1
gpcheck=1
gpgkey=file:///media/RHEL_5.4%20x86_64%20DVD/RPM-GPG-KEY-redhat-release

3、清空yum緩存配置，使新路徑生效

1. [root@localhost ~]# yum clean all
2. Loaded plugins: fastestmirror
3. Cleaning up Everything
4. Cleaning up list of fastest mirrors

至此配置完成，yum就可以使用了，不過下次使用的時候記得加載光盤或者設置為開機自動加載。
