HA高可用實驗報錯

做HA實驗時，啟動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.

因為Linux是64位的，ha.cf 配置檔案裡

/usr/lib/heartbeat/ipfail 這一句要改為：

/usr/lib64/heartbeat/ipfail

再次啟動/etc/init.d/heartbeat start

Starting High-Availability services: INFO:  Resource is stopped

Done.
