HA 高可用

作HA實驗時，啓動heartbeat出現錯誤：

   ERROR: Client child command [/usr/lib/heartbeat/ipfail] is not executable

   ERROR: Heartbeat not started: configuration error.

   ERROR: Configuration error, heartbeat not started.

由於Linux是64位的，ha.cf 配置文件裏

/usr/lib/heartbeat/ipfail 這一句要改成：

/usr/lib64/heartbeat/ipfail

再次啓動/etc/init.d/heartbeat start

Starting High-Availability services: INFO:  Resource is stopped

Done.

成功
