heartbeat產生大量nodename日誌，這正常嗎？
用虛擬機測試，兩台伺服器heartbeat服務都起來后，情況如下：
看了下日誌，發現大量的 nodename linuxtwo.com uuid changed to linuxone.com，這個正常嗎？
伺服器一:

《解決方案》
/etc/ha.d/resoource.d/LVSSyncDaemonSwap master status
應該是一台機器為stop 一台為running
你的兩台機器 eth0:0都為92.168.0.194 ?
《解決方案》
問題出在這裡啊，我兩台伺服器都有eth0:0
我也絕的不對，但是可以使用。
我用http://192.168.0.194刷網頁，可以看到
this is 192.168.0.192
然後我關閉192.168.0.192
等兩分鐘，我再用http://192.168.0.194刷網頁，可以看到
this is 192.168.0.193

*ip addr sh 檢查IP分配是否正確
*ipvsadm -L -n 檢查服務情況
*/etc/ha.d/resource.d/LVSSyncyncDaemonSwap master status 檢查均衡情況,正確應該是master上為on, Slave上為off
*特別注意認真閱讀文檔!!!
Note that a netmask of 255.255.255.255 on the lo:0 interface indicates that this interface will only accept traffic 192.168.6.240.

/etc/ha.d/ldirectord 在參考中一個只也沒有提過，不知道ls講是的什麼
我的heartbeat 用命令yum安裝的，
只有一條安裝命令yum install heartbeat*
沒有發現/etc/ha.d/ldirectord這個文件，我聲明下，我模擬的只是ha，不包括lvs的。
我的參考資料是：
http://www.clusting.com/cluster/HA/heartbeat_1.html
