LVS客户端启动脚本

deci

在设置LVS客户端时，如果我们使用手工设置的话会比较麻烦。现在我们直接使用脚本来启动lvs-client就OK了，下面是一个简单的脚本。

VIP地址：10.0.0.230,把文件放到/etc/init.d/目录下，并受于755的权限就可以使用service来启动和停止了，同时也可以使用chkconfig添加为开机启动


#!/bin/bash

#description:this script  to start lvs client for the server

start(){
    ifconfig | grep $VIP >/dev/null 2>&1
    if [ $? -eq 0 ];then
        action "LVS client program  already start"
        exit 0
    fi
    ifconfig lo:0 $VIP/32 up
    route add -host $VIP eth0
    echo "1" >/proc/sys/net/ipv4/conf/lo/arp_ignore
    echo "2" >/proc/sys/net/ipv4/conf/lo/arp_announce
    echo "1" >/proc/sys/net/ipv4/conf/all/arp_ignore
    echo "2" >/proc/sys/net/ipv4/conf/all/arp_announce
}
stop(){
    ifconfig | grep $VIP >/dev/null 2>&1
    if [ $? -gt 0 ];then
        action "LVS client program already stop"
        exit 1
    fi
    ifconfig lo:0 $VIP/32 down
    route del -host $VIP eth0
    echo "0" >/proc/sys/net/ipv4/conf/lo/arp_ignore
