Installation guide

Warning

Turning any of the above services on using chkconfig does not actually start the daemon. T o

do this use the /sbin/service command. See Section 2.3, “Starting the Piranha

Configurat ion Tool Service” for an example of how to use the /sbin/service command.

For more information on runlevels and configuring services with ntsysv and the Services

Configurat ion Tool, refer to the chapter titled "Controlling Access to Services" in the Red Hat

Enterprise Linux System Administration Guide.

2.2. Setting a Password for the Piranha Configuration Tool

Before using the Piranha Configuration Tool for the first time on the primary LVS router, you must

restrict access to it by creating a password. To do this, login as root and issue the following command:

/usr/sbin/piranha-passwd

After entering this command, create the administrative password when prompted.

Warning

For a password to be more secure, it should not contain proper nouns, commonly used acronyms,

or words in a dictionary from any language. Do not leave the password unencrypted anywhere on

the system.

If the password is changed during an active Piranha Configurat ion Tool session, the administrator is

prompted to provide the new password.

2.3. Starting the Piranha Configuration Tool Service

After you have set the password for the Piranha Configurat ion Tool, start or restart the piranha-

gui service located in /etc/rc.d/init.d/piranha-gui. T o do this, type the following command as

root:

/sbin/service piranha-gui start

/sbin/service piranha-gui restart

Issuing this command starts a private session of the Apache HT TP 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:

1. T he Apache HTTP Server must be installed on the system.

2. Stopping or restarting the Apache HT TP Server via the service command stops the piranha-

gui service.
