2.结尾查看 sudo tac /var/log/messages|grep Keepalived|less

分别启动keepalived
service keepalived restart

rel1和rel2机分别配置

/sbin/ifconfig lo:0 $VIP netmask 255.255.255.255 broadcast $VIP

/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
