The LifeKeeper GUI is included in the steeleye-lkGUI software package, which is bundled with the LifeKeeper Core Package Cluster. The steeleye-lkGUI package:
Installs the LifeKeeper GUI Client in Java archive format.
Installs the LifeKeeper GUI Server and modifies /etc/inittab to include the GUI server.
Installs the LifeKeeper administration web server, mhttpd, and modifies /etc/inittab to include the web server.
Note: The LifeKeeper administration web server is configured to use port 81, which should be different from any public web server.
Installs a Java policy file in /opt/LifeKeeper/htdoc/ which contains the minimum permissions required to run the LifeKeeper GUI. The LifeKeeper GUI application uses the java.policy file in this location for access control.
Prepares LifeKeeper for GUI administration.
Before continuing, you should ensure that the LifeKeeper GUI package has been installed on the LifeKeeper server(s). You can enter the command rpm -qi steeleye-lkGUI to verify that this package is installed. You should see output including the package name steeleye-lkGUI if the GUI package is installed.
Perform the following steps for each LifeKeeper server. Each step contains references or links for more detailed instructions.
You must install the Java Runtime Environment (JRE) or Java Software Development Kit (JDK) on each server. See the LifeKeeper Release Notes for the required Java version and URL to access the required download. Note: You may install the JRE from the LifeKeeper Installation Support CD by running the setup script on the Installation Support CD, and opting only to install the JRE. (See the "Setup Your LifeKeeper Environment Using the LifeKeeper Installation Support CD" section in the LifeKeeper Planning and Installation Guide for more information.)
Start the LifeKeeper GUI Server on each server (see Starting/Stopping the GUI Server). Note: Once the GUI Server has been started following an initial installation, starting and stopping LifeKeeper will start and stop all LifeKeeper daemon processes including the GUI Server.
If you plan to allow users other than root to use the GUI then you need to Configure GUI Users.
You can run the LifeKeeper GUI:
on the LifeKeeper server in the cluster and/or
on a remote system outside the cluster
See Running the GUI on the LifeKeeper Server for information on configuring and running the GUI on a server in the in your LifeKeeper cluster.
See Running the GUI on a Remote System for information on configuring and running the GUI on a remote system outside your LifeKeeper cluster.
