Chapter 10. Configuring the LVS Routers with Piranha Configuration Tool 135
Next either open an ssh session to the backup router or log into the machine as root and
type the following command:
/sbin/service iptables restart
Once you have copied these files over to the backup router and started the appropriate
services (see Section 8.1 Configuring Services on the LVS Routers for more on this topic)
you are ready to start the cluster.
10.8. Starting the Cluster
To start the LVS cluster, it is best to have two root terminals open simultaneously or two
simultaneous root open ssh sessions to the primary LVS router.
In one terminal, watch the kernel log messages with the command:
tail -f /var/log/messages
Then start the cluster by typing the following command into the other terminal:
/sbin/service pulse start
Follow the progress of the pulse service’s startup in the terminal with the kernel log
messages. When you see the following output, the pulse daemon has started properly:
gratuitous lvs arps finished
To stop watching /var/log/messages, type [Ctrl]-[c].
From this point on, the primary LVS router is also the active LVS router. While you can
make requests to the cluster at this point, you should start the backup LVS router before
putting the cluster into service. To do this, simply repeat the process described above on
the backup LVS router node.
After completing this final step, the cluster will be up and running.
