1.2 Installing a Web Server

Retain requires a web server on each server running a Retain component (Server, Worker, etc.).

1.2.1 Linux Web Server

  1. Install the Apache Web Server distributed with your SLES server.

  2. Make sure you also select and install the following Apache components:

    • apache2-mod_jk - Connectors between Apache and Tomcat Servlet Container

    • apache2-prefork - Apache 2 "prefork" MPM (Multi-Processing Module)

    • apache2-worker - Apache 2 worker MPM (Multi-Processing Module)

1.2.2 Windows Web Server

NOTE:Micro Focus recommends using IIS on Windows, but Apache can be used if necessary. See the Apache web site for installation instructions.

If you must use Apache instead of IIS, skip to (Optional) Apache Install on Windows. Otherwise, continue with this section.

  1. If you are using IIS and it is not already installed, install it now along with the ISAPI Extensions and Filters.

    The ISAPI Extensions and Filters allow Retain to gather and manipulate information about Internet traffic on the system.

  2. If your system has IIS installed and running without the ISAPI components, do the following:

    1. Open the Server Manager.

    2. In Server Manager, click the Manage menu, then click Add Roles and Features.

    3. In the Add Roles and Features wizard, click Next.

    4. Select the installation type and click Next.

    5. Select the destination server and click Next.

    6. On the Server Roles page, expand Web Server (IIS), expand Web Server, expand Application Development, and then select ISAPI Filters and ISAPI Extensions.

    7. Click Next.

    8. On the Select Features page, click Next.

    9. On the Confirm Installation Selections page, click Install.

    10. On the Results page, click Close.

1.2.3 (Optional) Apache Install on Windows

If you need to use Apache instead of IIS, do the following:

  1. Download the 2.2.x binary for Windows from apache.org.

    IMPORTANT:Retain only supports version 2.2.x.

  2. Install normally, accepting all of the defaults.
