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。

		ifconfig lo:0  down
