This section provides an overview of the LVS configuration tool available with Red Hat Cluster Suite — the Piranha Configuration Tool. The Piranha Configuration Tool is a Web-browser graphical user interface (GUI) that provides a structured approach to creating the configuration file for LVS — /etc/sysconfig/ha/lvs.cf.

To access the Piranha Configuration Tool you need the piranha-gui service running on the active LVS router. You can access the Piranha Configuration Tool locally or remotely with a Web browser. You can access it locally with this URL: https://localhost:3636. You can access it remotely with either the hostname or the real IP address followed by :3636. If you are accessing the Piranha Configuration Tool remotely, you need an ssh connection to the active LVS router as the root user.

Starting the Piranha Configuration Tool causes the Piranha Configuration Tool welcome page to be displayed (refer to Figure 1.29, “The Welcome Panel”). Logging in to the welcome page provides access to the four main screens or panels: CONTROL/MONITORING, GLOBAL SETTINGS, REDUNDANCY, and VIRTUAL SERVERS. In addition, the VIRTUAL SERVERS panel contains four subsections. The CONTROL/MONITORING panel is the first panel displayed after you log in at the welcome screen.
