解决keepalived脑裂问题解决方案

主服务器上写一个脚本

#!bin/bash

kep_eth1=192.168.100.128

while true

ping -c 3 -w 2 $kep_eth1 &> /dev/null

if [ `echo "$?" -ne "0" ];then

/etc/init.d/keepalived stop

echo “kep_eth 1 can’t working”

elif [ `ss -antup | grep "nginx" |wc -l` -eq "0"];then

/etc/init.d/keepalived stop

echo “nginx is stoping！”

sleep 5

done

#当keepalived备服务器Eth1 因某种无法连接时则停止主keepalived服务，避免出现脑裂问题

#当主服务器监测本地nginx服务异常或关闭是则关闭本地keepalived服务避免出现脑裂问题

2.备服务器上写一个脚本

#!bin/bash

vip=192.168.200.5

while true

ip -a | grep "$vip"

if [ "$?" -eq "0" ];then

echo “my keepalived is working!”

Done

#当备服务器本机监测到自己有VIP时则通知管理员
