# RS端配置步骤

#### 操作步骤

每台RS上都需要做以下步骤。


1. 修改内核参数禁用RS端响应ARP广播功能。
  1 echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore

  1 echo 1 > /proc/sys/net/ipv4/conf/lo/arp_ignore

  1 echo 2 > /proc/sys/net/ipv4/conf/all/arp_announce

  1 echo 2 > /proc/sys/net/ipv4/conf/lo/arp_announce

2. 配置RS端的虚拟IP地址（以192.168.1.2为例）。
  1 ifconfig lo:0 192.168.1.100 netmask 255.255.255.255 broadcast 192.168.1.100 up

  1 route add -host 192.168.1.100 dev lo:0


#### 配置脚本示例

上述2个步骤可写入脚本中在服务器任意一个目录直接执行，脚本示例如下。

```
#!/bin/bash
#description:Set vip of Real Server
if [ $# -eq 0 ];then
        echo "usage: $0 start/stop"
        exit 1
fi
viplist=('192.168.1.100')
mask=255.255.255.255
case $1 in
start)
 echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore
 echo 1 > /proc/sys/net/ipv4/conf/lo/arp_ignore
 echo 2 > /proc/sys/net/ipv4/conf/all/arp_announce
 echo 2 > /proc/sys/net/ipv4/conf/lo/arp_announce
 for vip in ${viplist[@]}
        do
  ifconfig lo:0 $vip netmask $mask  broadcast $vip up
 route add -host $vip dev lo:0
        done
;;
stop)
 echo 0 > /proc/sys/net/ipv4/conf/all/arp_ignore
 echo 0 > /proc/sys/net/ipv4/conf/lo/arp_ignore
 echo 0 > /proc/sys/net/ipv4/conf/all/arp_announce
 echo 0 > /proc/sys/net/ipv4/conf/lo/arp_announce

        for vip in ${viplist[@]}
        do
  route del -host $vip dev lo:0
  ifconfig lo:0  down
        done

;;
esac
```
