[centos]设置光盘为yum源

设置光盘为yum源
1.挂载光盘到指定目录
# mount -t auto /dev/cdrom /media/centos
mount: block device /dev/sr0 is write-protected, mounting read-only


2.禁用网络更新方式：
/etc/yum.repos.d/
CentOS-Base.repo改名为CentOS-Base.repo.bak


3.配置本地yum源
CentOS-Media.repo
[c6-media]
name=CentOS-$releasever - Media
baseurl=file:///media/centos/
#        file:///media/cdrom/
#        file:///media/cdrecorder/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6


4.清除原来的yum信息
yum clean all


5.查看新源列表
yum list
