大家都知道RHN官方是收费的， RHEL6本地的YUM源。，其实在网上有很多yum的资料，但是都并不是我想要的，废话不多说了，直接用最简单的方法去做事情。
如下yum配置所示：
1：新建一个目录tony，将光盘的所有内容复制到tony目录。
[root@tony /]# mkdir tony
[root@tony /]# cp -a /media/RHEL_6.0\ i386\ Disc\ 1/* /tony
2：在rhel6中/etc/yum.repos.d/下没有.repo文件，需要手工新建一个repo文件。
[root@tony /]# vi /etc/yum.repos.d/tony.repo
编辑文件：
[tony]
name=tony
baseurl=file:///tony/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release （这个gpgcheck必须有）
3：接下来就可以使用yum安装、删除安装包了。
yum install 软件名 安装软件
yum clean all 清除缓存
yum remove 软件名 移除软件
4：安装dhcp软件包，如下所示：
[root@tony /]# yum install dhcp
Loaded plugins: refresh-packagekit, rhnplugin
This system is not registered with RHN.
RHN support will be disabled.
tony | 3.7 kB 00:00 ...
tony/primary_db | 2.3 MB 00:00 ...
Setting up Install Process

Nothing to do
[root@tony /]# yum clean all
Loaded plugins: refresh-packagekit, rhnplugin
Cleaning up Everything
[root@tony /]# yum remove dhcp

接下来就查看是否安装上dhcp软件，
[root@tony /]# rpm -qa dhcp
dhcp-4.1.1-12.P1.el6.i686
ok！本次技术共享就到此结束，希望广大网友能给予本人支持。
