[gpfsug-discuss] Changing Web ports for the Spectrum Scale GUI

Thu Aug 23 10:24:38 BST 2018

Hello Markus,

I’m not sure how to interpret your answer:
Do the internal processes connect to the non-privileged ports (47443 and 47080) or the privileged ports?

If they use the privileged ports we would appreciate it if IBM could change that behavior to using the non-privileged ports so one could change the privileged ones or use a httpd server in front of the GUI web service.

We are going to need this in the near future as well…

Thanks & kind regards.

Hello Keith,

it is not so easy.

The GUI receives events from other scale components using the currently defined ports.
Changing the GUI ports will cause breakage in the GUI stack at several places (internal watchdog functions, interlock with health events, interlock with CES).
Therefore at this point there is no procedure to change this behaviour across all components.

Because the GUI service does not run as root. the GUI server does not serve the privileged ports 80 and 443 directly but rather 47443 and 47080.
Tweaking the ports in the server.xml file will only change the native ports that the GUI uses.
The GUI manages IPTABLES rules to forward ports 443 and 80 to 47443 and 47080.
If these ports are already used by another service, the GUI will not start up.

Making the GUI ports freely configurable is therefore not a strightforward change, and currently no on our roadmap.
If you want to emphasize your case as future development item, please let me know.

I would also be interested in:
> Scale version you are running
> Do you need port 80 or 443 as well?
> Would it work for you if the xCAT service was bound to a single IP address?

Mit freundlichen Grüßen / Kind regards

Hello All,

Does anyone know how to change the HTTP ports for the Spectrum Scale GUI? Any documentation or RedPaper I have found deftly avoids discussing this. The most promising thing I see is in /opt/ibm/wlp/usr/servers/gpfsgui/server.xml:

    <httpEndpoint id="defaultHttpEndpoint" host="*" httpPort="47080" httpsPort="47443">
        <tcpOptions soReuseAddr="true"/>
    </httpEndpoint>

but it appears that port 80 specifically is used also by the GUI's Web service. I already have an HTTP server using port 80 for provisioning (xCAT), so would rather change the Specturm Scale GUI configuration if I can.

Many Thanks,
  Keith
