配置Linux双机热备之Heartheat，启动Ok！
[root@drbd02 ~]# /etc/init.d/heartbeat start
Starting High-Availability services:
2013/05/03_23:13:28 INFO: Resource is stopped
[确定]
[root@drbd02 ~]#
后因各种原因，修改了主机名，最近要用到Heartheat做测试，rpm查看了一下，各种包都有，果断的restart！
heartbeat[16379]: 2013/05/06_14:49:37 info: Version 2 support: false
heartbeat[16379]: 2013/05/06_14:49:37 ERROR: Current node [drbd01] not in configuration!
heartbeat[16379]: 2013/05/06_14:49:37 info: By default, cluster nodes are named by `uname -n` and must be declared with a 'node' directive in the ha.cf file.

heartbeat[16379]: 2013/05/06_14:49:37 ERROR: Configuration error, heartbeat not started.
看到第二行喽 ERROR: Current node [drbd01] not in configuration! 当前节点没有配置
配置文件各种找，功夫不负有心人，在ha.cf配置文件的214、215行找到了当时配置的两个节点
214 node ha01
215 node ha02
果断改成当前的主机名，restart！又没成功

问题出来了 ERROR: Bad nodename in /etc/ha.d/haresources [ha01]！太不认真了！改之。。。
[root@drbd01 ~]# vim /etc/ha.d/haresources
151 drbd01 192.168.0.200 httpd
restart。。。
[root@drbd01 ~]# /etc/init.d/heartbeat restart

仅以此献给那些跟我犯一样低级错误的同僚们！
