一：挂载本地光盘到系统
如果服务器是虚拟机，可以通过vSphere Client进入控制平台，在“编辑设置”——>“硬件”——>“CD/DVD驱动器”里指定操作系统的ISO镜像文件。
如果是物理机，则需要进入机房找到服务器，在光驱里面放入安装光盘。这个相对而言比较麻烦，所以一般最好复制光盘文件到本地硬盘。
方法1：光驱挂载镜像
[root@localhost ~]# mkdir /mnt/cdrom
[root@localhost ~]# mount -t iso9660 /dev/cdrom /mnt/cdrom
mount: block device /dev/sr0 is write-protected, mounting read-only
[root@localhost ~]#
方式2：复制光盘文件【远程YUM源可以使用此方法】
文件/tmp/rehl6.tar.gz是从光盘打包复制过来的，顺便解压到到指定目录/mnt/cdrom
[root@localhost ~]# mkdir /mnt/cdrom/
[root@localhost ~]tar zxvf /tmp/rehl6.tar.gz -C /mnt/cdrom/
二：配置本地YUM源
[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# ls
redhat.repo rhel-source.repo
[root@localhost yum.repos.d]touch rhel-media.repo
[root@localhost yum.repos.d]# vi rhel-media.repo
[media]
name=Red Hat Enterprise Linux 6.6
baseurl=file:///mnt/cdrom

gpgcheck=1
gpgkey=file:///mnt/cdrom/RPM-GPG-KEY-redhat-release
