因为现在的rhel5在安装过程中提示输入INstall Number来定制安装的软件包？默认选择一部分，成功进入系统后！想通过添加删除程序来做，
结果和Enterprise 4有改变！
应用程序---添加/删除软件 （当鼠标移到上面的时候提示：改变系统上已安装的软件包），所以进入后，看到可以删除已经安装的软件包，但
是无法添加未安装的软件包！
所以打算挂载本地自己制作的rhel-5-server-dvd.iso来解决本地自由添加删除程序问题！
说明不需要更改/etc/yum.conf文件内容，建立/media/rhel目录
1. mount -o loop rhel-5-server-dvd.iso /media/rhel
2. vi /etc/yum.repos.d/rhel-local.repo
[Cluster]

baseurl=file：///media/rhel/Cluster

[ClusterStorage]

[root@rhel5 ~]# mkdir -p /var/rhel/{Cluster,ClusterStorage,Server,VT}
[root@rhel5 ~]# cd /var/rhel/
[root@rhel5 rhel]# ls
Cluster ClusterStorage Server VT
[root@rhel5 rhel5]# rpm -vih /media/rhel/Server/createrepo-0.4.4-2.fc6.noarch.rpm
4. createrepo -o /var/rhel/Cluster -g /media/rhel/Cluster/repodata/comps-rhel5-cluster.xml /media/rhel/Cluster
createrepo -o /var/rhel/ClusterStorage -g /media/rhel/ClusterStorage/repodata/comps-rhel5-cluster-st.xml
/media/rhel/ClusterStorage
createrepo -o /var/rhel/Server -g /media/rhel/Server/repodata/comps-rhel5-server-core.xml /media/rhel/Server
createrepo -o /var/rhel/VT -g /media/rhel/VT/repodata/comps-rhel5-vt.xml /media/rhel/VT
5. mount --bind /var/rhel/Cluster/repodata /media/rhel/Cluster/repodata
mount --bind /var/rhel/ClusterStorage/repodata /media/rhel/ClusterStorage/repodata
mount --bind /var/rhel/Server/repodata /media/rhel/Server/repodata
mount --bind /var/rhel/VT/repodata /media/rhel/VT/repodata
[root@rhel5 rhel5]# yum clean all

然后再次 应用程序---添加/删除软件 时就可以正常的从本地添加删除rpm 包了
或者
[root@rhel5 rhel5]# system-config-packages
