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.

Warning |
| |
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 10.8 Starting the Cluster
for information on starting the pulse
service.
The Piranha Configuration Tool runs
on port 3636 by default. To change this port number, change the
line Listen 3636 in Section 2
of the piranha-gui Web server
configuration file /etc/sysconfig/ha/conf/httpd.conf.
To use the Piranha Configuration Tool
you need at minimum a text-only Web browser. If you start a Web
browser on the primary LVS router, open the location https://localhost:3636. You can reach the
Piranha Configuration Tool from anywhere
via Web browser by replacing localhost with the hostname or IP address of
the primary LVS router.
When your browser connects to the Piranha
Configuration Tool, you must login to access the cluster
configuration services. Enter piranha
in the Username field and the password set
with piranha-passwd in the Password field.
Now that the Piranha Configuration
Tool is running, you may wish to consider limiting who has
access to the tool over the network. The next section reviews ways
to accomplish this task.
