Configure an Apache Web Agent Using GUI or Console Mode

These instructions are for GUI and Console Mode configuration. The steps for the two modes are the same, with these exceptions for Console Mode:

• You may be instructed to select an option by entering a corresponding number. For example, to select the Apache Web Server, you enter a 1, which corresponds to this server.
• Press ENTER after each step to proceed through the process instead of "clicking Next," as stated in the following procedure.
• All passwords that you enter are displayed in clear text. To workaround this issue, run the installation in GUI or unattended mode.

The prompts for each mode will help guide you through the process.

• web_agent_home

  Indicates the directory where the Web Agent is installed.

  Default (Windows installations): C:\Program Files\CA\webagent

  Default (UNIX installations): /opt/ca/webagent

To configure the Apache Web Agent

1. If necessary, start the Configuration Wizard.
   1. Open a console window.
   2. Navigate to web_agent_home/install_config_info
   3. Enter one of the following commands:

      GUI mode: ./ca-wa-config.bin

      Console mode: ./ca-wa-config.bin -i console

2. If you have already done host registration, skip to the next step. Otherwise, select the option to skip host registration, then click Next.

   To register the trusted host, go to the installation chapter for your platform.

3. In the Select Web server(s) dialog box, select the option for the Apache Web Sever and click Next.
4. In the Apache Web Server Path dialog box, specify the Apache Web Server root, for example, /opt/apache2. Click Next.

   If you installed the Agent on an Apache-based server, such as an IBM HTTP Server, or Oracle server, the Web Agent may not recognize the path. In this case, the Configuration Wizard displays the Apache Web Server Failure dialog box with the following options:

   • I would like to re-enter the Apache Server Root.

     Select this option for an Apache web server and re-enter the root path.

   • I would like to enter a specific configuration path.

     Select this option if you are using an Apache-based web server (such as IBM HTTP, HP Apache-based, or Oracle). You are prompted to enter the full configuration path to the web server root.

   • I don't have an Apache web server.

     Choose this option to skip Apache configuration and continue with the Agent configuration.

   Click Next.

5. Following the server root path, specify the version of Apache you are using. Select from these two options:
   • Apache version 1.0
   • Apache version 2.0
6. Select the web server instances that you want to configure with Web Agents.

   If you have already configured a server with a Web Agent and you are running the Configuration Wizard to configure additional web servers instances, the Wizard displays the Select One or More Instances to Overwrite dialog box. This dialog box lists the web servers that you have previously configured.

   1. Select one of the following:

      Overwrite—to overwrite the server instance configuration.

      Preserve—to preserve the web servers configuration.

      Important! If you uncheck a previously configured server, the Web Agent will be removed from this server.

   2. Click Next.
7. In the Agent Configuration Object field, enter the name of the Agent Configuration Object for this web server instance.

   This name must match an Agent Configuration Object already defined at the Policy Server. For example, to use the default enter ApacheDefaultSettings.

8. If you want to configure Self Registration for DMS2, select Yes. If not, select No.

   A servlet engine is required to run Self Registration. If the Web Agent Configuration Wizard does not detect a servlet engine, the Select Servlet Engine for Registration dialog box is not displayed.

   If you selected Yes to configure Self Registration:

   1. Select a servlet engine to be configured for the web server. If you do not see your engine displayed, select Other Advanced server. Click Next.
   2. In the Self Registration Services Admin Account dialog box, identify the the DMS Administrator by provide values for the Admin User Name, Admin Password and Admin Confirm Password fields and click Next.

      The user name and password that you enter here must match the DMS Admin values you set at the Policy Server.

      The DMS Administrator account secures DMS requests that are performed outside of the scope of a DMS administrator, such as self-registration. The user name and encrypted password for the account are stored in the dms.properties file on the Web Agent.

9. In the Web Server Configuration Summary dialog box. Confirm that the configuration settings are correct, then click Install.

   The Web Agent files are installed.

10. Click Done when the installation is complete.
11. Enable the Web Agent:
    1. Open the WebAgent.conf file, located as follows:

       Apache_home/conf

    2. Set the EnableWebAgent parameter to yes.
    3. Save and close the file.
12. Restart the web server.

    When you run the Configuration Wizard for the Apache Web Agent, it makes changes to the Web Server's httpd.conf file and to the library path.

    For httpd.conf changes to take effect, you need to restart the web server.

13. For Apache on UNIX systems, optimize the Apache Web Agent by tuning the shared memory segments.
