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.
