2.3.2 后台真实服务器虚拟地址配置：

在小频道真实服务器 124.238.253.155/124.238.253.188 执行如下脚本 #/home/tools/lvs.sh start Lvs.sh 脚本内容: #!/bin/bash

#description:start realserver #chkconfig 235 26 26

VIP1=124.238.253.100

VIP2=124.238.253.101 /etc/rc.d/init.d/functions case \start)

echo \

/sbin/ifconfig lo:0 $VIP1 broadcast $VIP1 netmask 255.255.255.255 up /sbin/ifconfig lo:1 $VIP2 broadcast $VIP2 netmask 255.255.255.255 up echo \echo \echo \echo \;; stop)

/sbin/ifconfig lo:0 down /sbin/ifconfig lo:1 down

echo \

echo \echo \echo \echo \;; *)

echo \exit 1 esac

# shell end

3 第三部分：应用管理：

3.1 启动/关闭lvs调度器：

启动lvs

#/usr/local/sbin/keepalived –D -f /usr/local/etc/keepalived/keepalived.conf 关闭lvs

# killall -9 keepalived;ipvsadm -C

3.2 系统虚拟IP管理:

查看虚拟IP地址 # ip address list 删除虚拟IP地址
