1. 从windows，将安装盘中的如下4个文件拷贝到redhat系统的某个目录下（比如/mnt/udisk）
[root@redhat ~]# ll /mnt/udisk/
total 264
drwxr-xr-x 2 root root 258048 Dec 15 18:46Packages
drwxr-xr-x 2 root root 4096 Dec 15 18:46repodata
-rw-r--r-- 1 root root 3375 Dec 15 18:46RPM-GPG-KEY-redhat-beta
-rw-r--r-- 1 root root 3211 Dec 15 18:46RPM-GPG-KEY-redhat-release
2. 配置yum文件，增加如下项
[root@redhat ~]# cat /etc/yum.repos.d/rhel-source.repo
[rhel-source-iso]
name=udisk for Redhat
baseurl=file:///mnt/udisk
enabled=1
gpgcheck=0
gpgkey=file:///mnt/udisk/RPM-GPG-KEY-redhat-beta,file:///mnt/udisk/RPM-GPG-KEY-redhat-release
3. 更新yum源
[root@redhat ~]# yum update
OK~~~
