Managing addresses and ports for HTTP Server (powered by Apache)

 

This topic provides information about how to manage addresses and ports for your IBM HTTP Server with the Web Administration for i5/OS interface.

Information for this topic supports the latest PTF levels for HTTP Server for iSeries . IBM recommends that you install the latest PTFs to upgrade to the latest level of the HTTP Server for i5/OS. Some of the topics documented here are not available prior to this update. See IBM Service for more information.

Most browsers make HTTP requests on ports 80 and 443 by default. Typically, the default configuration option is for servers to listen on all IP addresses on port 80. Multiple servers cannot listen on the same port and IP numbers. Multiple servers may listen on the same IP address, but require a unique port, or they may listen on the same port, but require a unique IP address. If you want each server to listen on port 80, then you should configure each server to listen on a specific unique IP address.

If you add another Web server product such as Lotus® Domino® (with the HTTP task enabled) on the same iSeries™, it cannot listen on the same IP address and the same port as the HTTP Server.

You can change the IP address or port for your server by doing the following:

  1. Click the Manage tab.

  2. Click the HTTP Servers subtab.

  3. Select your HTTP Server name from the Server list.

  4. Expand Server Properties.

  5. Click General Server Configuration.

  6. Click the General Settings tab in the form.

  7. Do one of the following:

    • Select an existing IP address and port from the Server IP address and port to listen on table to modify or delete.

    • Click Add under the Server IP address and ports to listen on table to add a new IP address and port.

  8. Click Enabled or Disabled in the FRCA column. Only select Enabled if you are using or will be using FRCA.

  9. Click Continue.

  10. Click OK.
