lvs已经编译到linux内核中，只需要安装lvs的管理软件ipvsadm即可

1. 插入光盘，查找设备

[root@chen ~]# ls -l /dev | grep cdrom

lrwxrwxrwx. 1 root root 3 12月 28 07:29 cdrom -> sr0

crw-rw----. 1 root cdrom 21, 1 12月 28 07:29 sg1

brw-rw----. 1 root cdrom 11, 0 12月 28 07:29 sr0

2. 加载光驱

[root@chen ~]# mount /dev/cdrom /mnt

mount: block device /dev/sr0 is write-protected, mounting read-only

3. 配置仓库

vi /etc/yum.repos.d/CentOS-Media.repo

修改前

# CentOS-Media.repo

#

# This repo can be used with mounted DVD media, verify the mount point for

# CentOS-6. You can use this repo and yum to install items directly off the

# DVD ISO that we release.

#

# To use this repo, put in your DVD and use it with the other repos too:

# yum --enablerepo=c6-media [command]

#

# or for ONLY the media repo, do this:

#

# yum --disablerepo=\* --enablerepo=c6-media [command]

[c6-media]

name=CentOS-$releasever - Media

baseurl=file:///media/CentOS/

file:///media/cdrom/

file:///media/cdrecorder/

gpgcheck=1

enabled=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6修改后
