1、准备工作

关闭selinux

#setenforce 0

创建yum目录

#mkdir /yum

挂载光盘

#mount -o loop /dev/cdrom /mnt

拷贝光盘内所有文件到本地目录

#cp -ar /mnt/* /yum

2、添加配置文件

修改repo文件，访问本地yum库

#vi /etc/yum.repos.d/local.repo

[local]
name=Red Hat Enterprise Linux update6
baseurl=file:///yum/
gpgcheck=0
enabled=1

删除或者备份原始repo文件，否则yumlist会报错如下：

#mv /etc/yum.repos.d/packagekit-media.repo /etc/yum.repos.d/packagekit-media.repo.bk
rhel6 Error: Cannot retrieve repository metadata (repomd.xml) for repository: InstallMedia. Please verify its path and try again

清除yum缓存

#yum clean all

3、测试

[root@rhel6 ~]# yum repolist
Loaded plugins: refresh-packagekit, rhnplugin
This system is not registered with RHN.
RHN support will be disabled.
repo id repo name status
local Red Hat Enterprise Linux update6 3,391
repolist: 3,391

看到上述信息，表示yum库创建成功
