问题日志：/var/log/ha-log ERROR: Message hist queue is filling up (451 messages in queue)
解决方法：将集群中的设备防火墙清空，service iptables stop即可
问题日志：ERROR: Client child command [/usr/lib/heartbeat/ipfail] is not executable
ERROR: Heartbeat not started: configuration error.
ERROR: Configuration error, heartbeat not started.
解决方法：因为Linux是64位的，ha.cf 配置文件里
/usr/lib/heartbeat/ipfail 这一句要改为：
/usr/lib64/heartbeat/ipfail
再次启动/etc/init.d/heartbeat start
Starting High-Availability services: INFO: Resource is stopped
Done.

#2 sha1 HI!
#3 md5 Hello!
改成
auth 3
#1 crc
#2 sha1 HI!
3 md5 Hello!
