###下面的日志为节点1，继续跟踪节点1的日志
###从下面的日志可以得知orasrv2.xlk.com: status up以及remote resource transition completed
heartbeat[4374]: 2015/11/06_11:50:23 info: Link orasrv2.xlk.com:eth0 up.
heartbeat[4374]: 2015/11/06_11:50:23 info: Status update for node orasrv2.xlk.com: status init
heartbeat[4374]: 2015/11/06_11:50:23 info: Status update for node orasrv2.xlk.com: status up
harc[4809]: 2015/11/06_11:50:23 info: Running /etc/ha.d/rc.d/status status
harc[4825]: 2015/11/06_11:50:23 info: Running /etc/ha.d/rc.d/status status
heartbeat[4374]: 2015/11/06_11:50:25 info: Status update for node orasrv2.xlk.com: status active
harc[4840]: 2015/11/06_11:50:25 info: Running /etc/ha.d/rc.d/status status
heartbeat[4374]: 2015/11/06_11:50:25 info: remote resource transition completed.
3、节点1停止heartbeat
###通过下面的命令来停止节点1上的heartbeat
[root@orasrv1 ~]# service heartbeat stop
Stopping High-Availability services:
Done.
###此时继续观察节点1的日志变化情况
heartbeat[4374]: 2015/11/06_11:53:13 info: Heartbeat shutdown in progress. (4374)
heartbeat[4873]: 2015/11/06_11:53:13 info: Giving up all HA resources. ###节点1开始放弃资源
ResourceManager[4886]: 2015/11/06_11:53:14 info: Releasing resource group: orasrv1.xlk.com IPaddr::192.168.21.1/24/eth0 httpd
ResourceManager[4886]: 2015/11/06_11:53:14 info: Running /etc/init.d/httpd stop ###停止httpd服务
ResourceManager[4886]: 2015/11/06_11:53:14 info: Running /etc/ha.d/resource.d/IPaddr 192.168.21.1/24/eth0 stop
IPaddr[4975]: 2015/11/06_11:53:14 INFO: ifconfig eth0:0 down
IPaddr[4946]: 2015/11/06_11:53:14 INFO: Success
heartbeat[4873]: 2015/11/06_11:53:14 info: All HA resources relinquished.
###所有的HA资源在节点1放弃完毕，下面开始kill heartbeat相关进程
heartbeat[4374]: 2015/11/06_11:53:15 WARN: 1 lost packet(s) for [orasrv2.xlk.com] [95:97]
heartbeat[4374]: 2015/11/06_11:53:15 info: No pkts missing from orasrv2.xlk.com!

heartbeat[4374]: 2015/11/06_11:53:16 info: orasrv1.xlk.com Heartbeat shutdown complete.
###观察节点2，此时也获取VIP
[root@orasrv2 ~]# ifconfig |grep eth -A1
eth0 Link encap:Ethernet HWaddr 00:0C:29:F1:2E:E4 #Author : Leshami
inet addr:192.168.21.13 Bcast:192.168.21.255 Mask:255.255.255.0
--
eth0:0 Link encap:Ethernet HWaddr 00:0C:29:F1:2E:E4 #Blog :
inet addr:192.168.21.1 Bcast:192.168.21.255 Mask:255.255.255.0
--
eth1 Link encap:Ethernet HWaddr 00:0C:29:F1:2E:EE
inet addr:192.168.144.129 Bcast:192.168.144.255 Mask:255.255.255.0
###验证httpd服务，如下，此时透过VIP访问到主页，从orasrv2，即节点2返回数据
orasrv2.xlk.com
4、使用hb_standby切换
###下面通过hb_standby将服务切换回节点1，切换前启动节点1上的heartbeat
[root@orasrv2 ~]# /usr/share/heartbeat/hb_standby
2015/11/06_11:56:05 Going standby [all].
###继续跟踪节点1的日志

###上面的日志表面，此时节点1已经启动完毕，并且2节点均处于活动状态
