3.3. Starting the Piranha Configuration Tool Service
After you have set the password for the Piranha Configuration Tool, start or restart the piranha-gui service located in /etc/rc.d/init.d/piranha-gui. To do this, type the following command as root:
/sbin/service piranha-gui start
or
/sbin/service piranha-gui restart
Issuing this command starts a private session of the Apache HTTP Server by calling the symbolic link /usr/sbin/piranha_gui -> /usr/sbin/httpd. For security reasons, the piranha-gui version of httpd runs as the piranha user in a separate process. The fact that piranha-gui leverages the httpd service means that:
The Apache HTTP Server must be installed on the system.
Stopping or restarting the Apache HTTP Server via the service command stops the piranha-gui service.
If the command /sbin/service httpd stop or /sbin/service httpd restart is issued on an LVS router, you must start the piranha-gui service by issuing the following command:
/sbin/service piranha-gui start
The piranha-gui service is all that is necessary to begin configuring an LVS cluster. However, if you are configuring the cluster remotely, the sshd service is also required. You do not need to start the pulse service until configuration using the Piranha Configuration Tool is complete. See Section 5.8, “Starting the Cluster” for information on starting the pulse service.
