The Cluster Configurator is a web-based interface for cluster configuration and administration. Instead of editing plain text configuration files of the ShaoLin HA Cluster software, and running cluster control commands on the command line, Cluster Configurator provides an easy to use web-based GUI. Cluster Configurator is a Webmin module, that means to use Cluster Configurator, you will need to connect to Webmin first. To connect to the Webmin server using a web browser, type http://your-server-ip:10000 in the URL dialog and your-server-ip is your server's IP address or hostname. The Cluster Configurator is under the system tab of the Webmin server, click the icon to enter the Cluster Configurator interface. Notice, you will need to login as root using the root password to configure ShaoLin HA Cluster.
