Configuring multiple Web servers and remote stand-alone application servers

This topic describes installing a Web server plug-in that WebSphere Application Server provides to communicate with a particular brand of Web server. This procedure describes installing multiple Web servers and their Web server plug-ins for WebSphere Application Server on one machine and multiple application servers on another machine.

Before you begin

Why and when to perform this task

Dedicated Web servers for each Application Server

Perform the following procedure to install the plug-ins and configure both Web servers and both application servers.

This topology lets each profile have unique applications, configuration settings, data, and log files, while sharing the same set of system files. Creating multiple profiles creates multiple application server environments that you can then dedicate to different purposes.

For example, each application server on a Web site can serve a different application. In another example, each application server can be a separate test environment that you assign to a programmer or a development team.

Attention:

A deployment manager by itself is also considered a remote scenario if the deployment manager has no managed nodes. Although multiple application servers are not shown in the preceding diagram, Machine B could have more than one application server profile.

Steps for this task

  1. Create the first application server profile using the Profile Creation wizard on Machine A.
  2. From the administrative console of the deployment manager, click System administration > Save Changes to Master Repository > Synchronize changes with Nodes > Save.
  3. Create the second application server profile using the Profile creation wizard on Machine A. Make the profile the default profile during the profile creation by selecting the check box on the appropriate panel.

    The script that the Plug-ins installation wizard creates works on the default profile only. So, this script can create only a Web server definition on the profile that is the default profile at the time that the script runs.

  4. Install a second IBM HTTP Server or another supported Web server on Machine B.
  5. On Machine B, install the Web server plug-ins to configure the second Web server using the Plug-ins installation wizard. Both Web servers share a single installation of the plug-in binaries but must be configured individually.
  6. The Plug-ins installation wizard creates a script named configureweb_server_name for the second Web server. The script is in the plugins_root/bin directory on Machine B. Copy the script to the app_server_root/bin directory on Machine A.
  7. Start the second application server.
  8. Run the configureweb_server_name script to create a Web server definition in the administrative console. You can then use the administrative console to manage the Web server.
  9. Propagate the plugin-cfg.xml file from the second application server to the Web server using the administrative console. Click Servers > Web server > Propagate Plug-in. Web servers other than IBM HTTP Server require manual propagation.
  10. Run the snoop servlet on the second Web server to verify that it is operational.

Result

This procedure results in installing two or more application servers on one machine and installing dedicated Web servers on another machine. This procedure installs the Web server plug-ins for both Web servers and configures both Web servers and both application servers.
