3.2. Installing Required Software

To install the software, follow these steps:

1. Make sure all servers in the cluster are running a supported release of Linux.

2. Depending on the servers and storage in the configuration and the Linux revision level, install the latest install patches that are required for the platform and applications.

3. On each system in the pool, install the version of the multiplexer driver that is appropriate to the operating system. Use the CD that accompanies the multiplexer. Reboot the system after installation.

4. On each node that is part of the pool, install the following software, in order:

   1. sysadm_base-tcpmux

   2. sysadm_base-lib

   3. sysadm_base-server

   4. cluster_admin

   5. cluster_services

   6. failsafe

   7. sysadm_failsafe-server

   Note: You must install sysadm_base-tcpmux, sysadm_base-server, and sysadm_failsafe packages on those nodes from which you want to run the FailSafe GUI. If you do not want to run the GUI on a specific node, you do not need to install these software packages on that node.

5. If the pool nodes are to be administered by a Web-based version of the Linux FailSafe Cluster Manager GUI, install the following subsystems, in order:

   1. IBMJava118-JRE

   2. sysadm_base-client

   3. sysadm_failsafe-web

      If the workstation launches the GUI client from a Web browser that supports Java™, install: java_plugin from the Linux FailSafe CD

      If the Java plug-in is not installed when the Linux FailSafe Manager GUI is run from a browser, the browser is redirected to http://java.sun.com/products/plugin/1.1/plugin-install.html

      After installing the Java plug-in, you must close all browser windows and restart the browser.

      For a non-Linux workstation, download the Java Plug-in from http://java.sun.com/products/plugin/1.1/plugin-install.html

      If the Java plug-in is not installed when the Linux FailSafe Manager GUI is run from a browser, the browser is redirected to this site.

   4. sysadm_failsafe-client

6. Install software on the administrative workstation (GUI client).

   If the workstation runs the GUI client from a Linux desktop, install these subsystems:

   1. IBMJava118-JRE

   2. sysadm_base-client

7. On the appropriate servers, install other optional software, such as storage management or network board software.

8. Install patches that are required for the platform and applications.
