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

4. 安装ipvsadm

[root@chen ~]# yum --disablerepo=\* --enablerepo=c6-media install ipvsadm
