keepalived的配置如下：

在MASTER上启动keepalived后，ip addr list无法看到vip

请问keepalived如何绑定vip呢？

xiaodylan

注意"{"是否和"}"配对，注意"{"和前面的字符串需要有1个空格，比如"VI_1 {"不要写成了"VI_1{"
绑定虚IP:
ifconfig lo:0 $VIP broadcast $VIP netmask 255.255.255.255 up
自己可以写一个脚本 如:

#!/bin/bash
#filename:real.sh
VIP=1.1.1.1
. /etc/rc.d/init.d/functions
case "$1" in
start)
     ifconfig lo:0 $VIP broadcast $VIP netmask 255.255.255.255 up
     /sbin/route add -host $VIP dev lo:0
     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
     sysctl -p >/dev/null 2>&1
     echo "realServer Start ok"
     ;;
stop)
     ifconfig lo:0 down
     route del $VIP >/dev/null 2>&1
     echo "0">/proc/sys/net/ipv4/conf/lo/arp_ignore
     echo "0">/proc/sys/net/ipv4/conf/lo/arp_announce
     echo "0">/proc/sys/net/ipv4/conf/all/arp_ignore
     echo "0">/proc/sys/net/ipv4/conf/all/arp_announce
     echo "realServer Stoped"
     ;;
*)
    echo "Usage0{start|stop}"
    exit 1
esac
exit 0
