5.4. Starting Heartbeat services

The Heartbeat services are started just as you would any other system service on your machine. Depending on your system platform, you might be using one of the following commands:

/etc/init.d/heartbeat start
service heartbeat start
rcheartbeat start

Through the pacemaker entry in your ha.cf, Heartbeat will now start the Pacemaker daemon (named crmd for historical reasons) along with the rest of its services. After a few seconds, you should be able to detect Heartbeat processes in your process table:

# ps -AHfww | grep heartbeat
root      2772  1639  0 14:27 pts/0    00:00:00         grep heartbeat
root      4175     1  0 Nov08 ?        00:37:57   heartbeat: master control process
root      4224  4175  0 Nov08 ?        00:01:13     heartbeat: FIFO reader
root      4227  4175  0 Nov08 ?        00:01:28     heartbeat: write: bcast eth2
root      4228  4175  0 Nov08 ?        00:01:29     heartbeat: read: bcast eth2
root      4229  4175  0 Nov08 ?        00:01:35     heartbeat: write: mcast bond0
root      4230  4175  0 Nov08 ?        00:01:32     heartbeat: read: mcast bond0
102       4233  4175  0 Nov08 ?        00:03:37     /usr/lib/heartbeat/ccm
102       4234  4175  0 Nov08 ?        00:15:02     /usr/lib/heartbeat/cib
root      4235  4175  0 Nov08 ?        00:17:14     /usr/lib/heartbeat/lrmd -r
root      4236  4175  0 Nov08 ?        00:02:48     /usr/lib/heartbeat/stonithd
102       4237  4175  0 Nov08 ?        00:00:54     /usr/lib/heartbeat/attrd
102       4238  4175  0 Nov08 ?        00:08:32     /usr/lib/heartbeat/crmd
102       5724  4238  0 Nov08 ?        00:04:47       /usr/lib/heartbeat/pengine

Finally, you should also be able to confirm that the cluster is working, via the Pacemaker crm_mon command:

# crm_mon -1
