192.168.1.66为浮动IP，这里显示资源服务mysqld已经启动起来了，trazilla为主机名

5、trazilla:/etc/ha.d# ifconfig eth0:0

eth0:0    Link encap:Ethernet  HWaddr 00:1A:A0:36:60:7A

inet addr:192.168.1.66  Bcast:192.168.1.255  Mask:255.255.255.0

UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

Interrupt:177

trazilla:/etc/ha.d#

如果这时候手动停止主机的mysqld，备用机监控不到主机的服务停止了。按资料上面heartbeat是会监控主机的资源服务的，如果down掉，自动接管过来，启动资源服务，分配IP。

实际测试却没有。而只有当主机或者heartbeat停止才会接管过来。

这是怎么回事呢？

在网上查了一下资料。原来Heartbeat目前不监视它启动的资源，查看它们是否正在运行，健康状态如何，以及客户端计算机是否能够抵达。

资料上提到采用mon来进行资源的监控，但似乎并不能达到实现资源服务的自动接管。

最后在局域网内测试成功。

资源服务的健康情况监控写脚本完成。部署到主服务器上，

如果检测到资源服务停止，那么停止主服务器上的heartbeat服务，这样备用服务器就能接管过来了。

附脚本。

pgrep="/usr/bin/pgrep"
