Editing web server configuration files

Edit web server configuration files to configure a Web server.

Before you begin

[AIX Solaris HP-UX Linux Windows] The Web Server Plug-ins Configuration Tool configures supported web servers. Use this topic to understand how the tool configures the web server configuration files.

[AIX Solaris HP-UX Linux Windows] If you must change a configuration for some reason, you can run the Web Server Plug-ins Configuration Tool again to re-configure the web server or you can edit the files.

Avoid trouble Avoid trouble: There are some web server configuration settings that cannot be edited:
  • The plugin-cfg.xml and plugin-key.kdb properties on the Servers > Server Types > Web servers > web_server_name > Plug-in Properties page of the administrative console are grayed-out because they cannot be edited.
  • After the web server definition is created, the /config/webserver_name value that is appended to the end of plugins_root cannot be edited.
gotcha

[AIX Solaris HP-UX Linux Windows] To support a nondefault profile, edit the configuration to point the web server to the correct location of the plug-in configuration file (plugin-cfg.xml). In this case, you would change the profile path from the default profile to the secondary profile.

[IBM i] Use the IBM® Web Administration for IBM i to configure IBM i web servers to communicate with a WebSphere® Application Server. Doing so automatically updates the web server configuration files as needed. See the topic about creating and configuring an HTTP server instance for more information.

[IBM i] If you must change a configuration for some reason, you can use the IBM Web Administration for IBM i to re-configure the web server, or you can edit the files. The recommended approach is to always use the IBM Web Administration for IBM i to configure the web server configuration file. However, sometimes you must edit the files.

You must determine whether your web server application uses a 32-bit or 64-bit architecture. If your machine supports a 64-bit architecture, you can use either a 32-bit or a 64-bit web server application. The following examples show how to determine which the architecture for your web server application:
  • For Apache-based web servers, including IBM HTTP Server, you can determine the architecture using the following techniques:
    • [AIX][HP-UX][Linux][Solaris] Run the command:
      apachectl -V | grep Architecture  

      This command displays the Architecture value for the web server, which will be either 32-bit or 64-bit.

    • [Windows] Run the following command from the IBM_HTTP_Server_install_root\bin directory:
      apache -V  

      Look for the value of the Architecture: line in the output. This value is either 32-bit or 64-bit.

  • For other, non-Apache based web servers, use the following techniques. These techniques also work for Apache-based web servers.
    • [AIX][HP-UX][Linux][Solaris] Run the file command against the primary web server application executable file to display its type. For example, run the following command on an AIX® system:
      file /usr/bin/httpd
      This command results in the following output:
      • For a 64-bit web server: httpd: 64-bit XCOFF executable ...
      • For a 32-bit web server: httpd: executable (RISC System/6000)...
      In general, if the output of the file command does not indicate 64 in the output, then the application is 32-bit application.
    • [Windows] Open the Microsoft Windows Task Manager when the server is running and locate the server in the process list. A 32-bit application has *32 after its name.

If the web server application uses a 64-bit architecture, the plug-in library should be loaded from the plugin_root/bin/64bit directory. If the web server application uses a 32-bit architecture, the plug-in library should be loaded from the plugin_root/bin/32bits directory. If the plugin_root/bin/64bits directory does not exist, you must use the 32-bit architecture.
