WebSphere Application Server V7.0: Concepts ... - IBM Redbooks

Installation
The installation process for all the components is fairly similar. All the installations
are started from the launchpad for the Network Deployment package. In the
following sections we describe the steps that had to be done to install each
component. We used a Windows environment to perform this installation.
Installing the Load Balancer (server A)
The Load Balancer component runs in server A and is used to distribute traffic
between our two Web servers.
Perform the following steps to install the Load Balancer:
1. Install the Load Balancer by performing the following steps:
a. Start the launchpad and click IBM Edge Components.
b. In the panel, click Launch the installation wizard for Edge Components
Load Balancer and Caching Proxy. This launches the installer.
c. Go through the panels accepting the default options.
2. Configure the load balanced cluster by performing the following steps:
a. Launch lbadmin.
b. Click Dispatcher → Connect to Host.
c. Click Dispatcher → Start Configuration Wizard.
d. Following the wizard panels, create a cluster with the new IP address and
add the two Web servers in it. The new IP address is the public address
that clients have to use to access the BeenThere application.
3. Configure loopback adapters in Web servers by performing the following
steps:
a. Add a loopback adapter in both HTTP server systems (server B and C).
b. Configure the cluster address in the loopback adapters.
c. Disable the Windows firewall (our servers’ operating system was Windows
XP).
