Configure the virtual host

 

A virtual host is a configuration entity that allows WebSphere Application Server to treat multiple host machines or port numbers as a single logical host (virtual host) for configuration purposes. Each virtual host can be associated with multiple aliases. Each alias is a particular host name and port number. Configure the virtual host to make resources available for client requests.

This topic assumes that you have started the administrative console. See Starting the administrative console if you have not yet attempted to start the application server.

You can use virtual hosts to combine multiple host machines into a single virtual host or to assign host machines to different virtual hosts. Virtual hosts separate and control WebSphere Application Server resources to make the resources available for client requests.

If your external HTTP server configuration uses ports other than the default ports, update the Host Aliases table for the virtual host to reflect the correct HTTP port number.

If your external HTTP server configuration uses the default port (80), skip these steps and go to Starting the HTTP server instance instead.

 

Overview

Use this procedure to update the Host Aliases table for the default_host virtual host from the administrative console.

 

Procedure

  1. Click Environment > Virtual Hosts in the left frame of the administrative console.

  2. Click default_host in the right frame.

  3. Click Host Aliases. The settings for default_host are displayed.

  4. Click the asterisk in the row that has a Port of 80 in the Host Name list.

    Host names are set to "*" when you install WebSphere Application Server.

  5. Specify the correct port number for your HTTP server in the Port field.

  6. Click OK, then click Save to save your configuration.

  7. After you specify a new port number, regenerate the plug-in configuration:

    1. Click Servers > Web servers.

    2. Select your Web server.

    3. Click Generate Plug-in.

    4. Click OK.

  8. After configuring the virtual host, start your HTTP server instance.

 

What to do next

For a standalone application server, restart the application server after you update the virtual host configuration.

Next: Go to Starting the HTTP server instance to continue the installation.
