Setting up a remote Web server

This topic describes how to create a Web server definition in the administrative console when the Web server and the Web server plug-in for WebSphere Application Server are on one machine and the application server is on another.

 

Before you begin

When creating a Web server definition using the WAS administrative console, by default, no applications are mapped for the Web server. To map applications, select your application in the WAS administrative console and map the application to an application server and Web server of your choice.

With a remote Web server installation, WAS can facilitate plug-in administration functions and generation and propagation of the plugin-cfg.xml file for IBM HTTP Server for WebSphere Application Server, but not for other Web servers.

Web servers that are not IBM HTTP Server for WAS must reside on the same machine as the WAS (as a managed node) to facilitate plug-in administration functions and generation and propagation of the plugin-cfg.xml file.

 

About this task

You can choose a remote Web server installation if you want the Web server on the outside of a firewall and WAS on the inside of a firewall. You can create a remote Web server on an unmanaged node. Unmanaged nodes are nodes without node agents. Because there is no WebSphere Application Server or node agent on the machine that the node represents, there is no way to administer a Web server on that unmanaged node unless the Web server is IBM HTTP Server for WebSphere Application Server. With IBM HTTP Server, there is an administration server that will facilitate administrative requests such as start and stop, view logs, and view and edit the httpd.conf file. The following steps will create a Web server definition in the default profile.

 

Procedure

  1. Install your WAS product.

    See Installing the product and additional software .

  2. Install IBM HTTP Server or another supported Web server.

    See Installing IBM HTTP Server .

  3. Install the binary plug-in module using the Plug-ins installation wizard.

    The Web server definition is automatically created and configured during the installation of the plug-ins.

    See Configuring a Web server and an application server on separate machines (remote) .

  4. Complete the setup by creating the Web server definition. Use the WAS administrative console or run the Plug-in configuration script:

    • Using the administrative console:

      1. Click System Administration > Nodes > Add Node to create an unmanaged node in which to define a Web server in the topology.

        See Manage nodes for more information.

      2. Click Servers > Web servers > New to launch the Create new Web server entry wizard. You will create the new Web server definition using this wizard. The wizard values are as follows:

        1. Select appropriate node

        2. Enter Web server properties:

          • Type: The Web server vendor type.

          • Port: The existing Web server port. The default is 80.

          • Installation Path: The Web server installation path. This field is required field for IBM HTTP Server only.

          • WINDOWS Service Name: The windows operating system service name of the Web server. The default is IBMHTTPServer6.0.

          • Use secure protocol: Use the HTTPS protocol to communicate with the Web server. The default is HTTP.

          • Plug-in installation location: The directory path where the plug-in is installed.

        3. Enter the remote Web server properties. The properties for the IBM HTTP Server administration server follow:

          • Port: The administration server port. The default is 8008.

          • User ID: The user ID that is created using the htpasswd script.

          • Password: The password that corresponds to the user ID created with the htpasswd script.

          • Use secure protocol: Use the HTTPS protocol to communicate with the administration server. The default is HTTP.

        4. Select a Web server template. Select a system template or a user-defined template for the Web server you want to create.

        5. Confirmation of Web server creation.

  5. For AIX, HP-UX, Linux or Solaris operating system: On the remote Web server, run the setupadm script. The administration server requires read and write access to configuration files and authentication files to perform Web server configuration data administration. You can find the setupadm script in the <IHS_install_root>/bin directory. The administration server has to execute adminctl restart as root to perform successful restarts of IBM HTTP Server. In addition to the Web server files, manually change the permissions to the targeted plug-in configuration files.

    The setupadm script prompts you for the following input:

    • User ID - The user ID that you use to log on to the administration server. The script creates this user ID.

    • Group name - The administration server accesses the configuration files and authentication files through group file permissions. The script creates the specified group through this script.

    • Directory - The directory where you can find configuration files and authentication files.

    • File name - The following file groups and file permissions change:

      • Single file name

      • File name with wildcard

      • All (default) - All of the files in the specific directory

    • Processing - The setupadm script changes the group and file permissions of the configuration files and authentication files.

    In addition to the Web server files, change the permissions to the targeted plug-in configuration files. See Setting permissions manually for instructions.

  6. For AIX, HP-UX, Linux, Solaris, or Windows operating system: On the remote Web server, run the htpasswd script. The administration server is installed with authentication enabled and a blank admin.passwd password file . The administration server will not accept a connection without a valid user ID and password. This is done to protect the IBM HTTP Server configuration file from unauthorized access.

    Launch the htpasswd utility that is shipped with the administration server. This utility creates and updates the files used to store user names and password for basic authentication. Locate htpasswd in the bin directory.

    • On Windows operating systems: htpasswd -cm <install_dir>\conf\admin.passwd [login name]

    • On AIX, HP-UX, Linux, and Solaris platforms: ./htpasswd -cm <install_dir>/conf/admin.passwd [login name]

    where <install_dir> is the IBM HTTP Server installation directory and [login name] is the user ID that you use to log into the administration server. The [login name] is the user ID that you entered in the user ID field for the remote Web server properties in the administrative console.

  7. Start IBM HTTP Server. Refer to Starting the IBM HTTP administration server for instructions.

 

What to do next

For a non-IBM HTTP Server Web Server on an unmanaged node, you can generate a plug-in configuration, based on WebSphere Application server repository changes. However, the following functions are not supported on an unmanaged node for a non-IBM HTTP Server Web server:

You can configure non-IBM HTTP Server Web servers as a local Web server on a managed node. For a non-IBM HTTP Server Web server on a managed node, the following functions are supported:

For a non-IBM HTTP Server Web server that is configured as a local Web server on a managed node, the following functions are not supported:
