用service命令启动该脚本
[*]# vim /etc/rc.d/init.d/lvs 输入上面的脚本内容（具体参数需要自己更改），保存
[*]# chmod 755 /etc/rc.d/init.d/lvs
[*]# service lvs start
[*]ipvsadm started
[*]# service lvs status
[*]ipvsadm OK
[*]# service lvs restart
[*]ipvsadm stoped
[*]ipvsadm started
[*]# service lvs stop
[*]ipvsadm stoped
使用chkconfig把lvs脚本添加到开机自启动项
[*]chkconfig --add lvs
[*]chkconfig --level 2345 lvs on
[*]chkconfig --list lvs
[*]lvs 0:关闭1:关闭2:启用3:启用4:启用5:启用6:关闭
在这个步骤的时候，遇到过一些麻烦，现问题已经解决，需要注意的是脚本中以下代码不能有错误，不然可能会遇到添加不上的情况，
[*]#!/bin/sh
[*]#
[*]# lvs Start lvs
[*]#
[*]# chkconfig: 2345 08 92
[*]# description:Starts, stops and saves lvs
[*]#
