安装光盘本地YUM更新源
挂载安装光盘：

复制代码代码如下:
mount /dev/cdrom /mnt
vi /etc/yum.repos.d/local.repo

修改本地更新源文件，添加内容：

复制代码代码如下:
[HightAvailability]
name=HightAvailability
baseurl=file:///mnt/HighAvailability
enable=1
gpgcheck=0


复制代码代码如下:
[LoadBalancer]
name=LoadBalancer
baseurl=file:///mnt/LoadBalancer
enable=1
gpgcheck=0


复制代码代码如下:
[Server]
name=Server
baseurl=file:///mnt/Server
enable=1
gpgcheck=0

PS：CentOS6.1更换为yum光盘源

复制代码代码如下:
#mkdir /media/CentOS
#mount /dev/cdrom /media/CentOS

测试

复制代码代码如下:
#yum --disablerepo=* --enablerepo=c6-media install gcc
