设置iptable后----heartbeat不能正常切换

Question

linux集群问题----heartbeat

前两天用两台机子做heartbeat ,主要提供WEB服务,配置完成后,当主服务器档机后,可以自动切换到辅助服务器上,实现了快速的故障转移,为了安全起见,我设置了iptables

iptables -P INPUT DROP
iptables -P OUTPUT ACCEPT
iptables -I INPUT -p tcp --dport 80 -j ACCEPT
iptables -I INPUT -p tcp --dport 22 -j ACCEPT
iptables -I INPUT -p udp --dport 694 -j ACCEPT
service iptables save

这样设置后,当主服务器档机后,却不能切换到辅助服务器上,不知道iptables哪设置错了,请大伙指教下,谢谢!!!

Answer 1

heartbeat use port 693  ??   u are sure u open the server port in iptables   ?
netstat -ant | grep LISTEN

and  u can see  ur heartbeat log in ur log file    , check the problem

Answer 2

Thank you for your help!!

I do not know the port heartbeat!

Answer 3

find  it in the /etc/ha.d/ha.cf     

didn't u   config it  ?

Answer 4

u  use iptables  , so  it  close the port of heartbeat     

then   heartbeat  cannot work , it  use ping  to know whether the master or slave  is living ?
