I've just setup graylog server on my ubuntu server using the the apt-get feature. Graylog is currently working with no issues, but I would like to change the port from 9000 to port 80/443. I can't seem to find any documentation on how to do that!

Running applications on ports lower than 1024 in Linux requires root or other types of escalated privileges. Since Java runs in a VM, it will not be able to SUID easily after starting as root.

The recommended way is to leave it run on the current port, on localhost, and put a reverse proxy in front of it (such as nginx or - easier, haproxy).

This is documented here.

~$ bin/graylog-web-interface -Dhttp.port=1234

  • Since I did not manually install it from the tar files, I don't have the bin folder that contains that file. – Yusof Feb 07 '16 at 19:11
  • This is the web interface startup command. Add the port parameter in your upstart script or wherever you start the web interface. – Lennart Koopmann Feb 07 '16 at 21:38

So you probably don't have the older /bin/graylog-web-interface but instead have:

root@ubuntu14:~# grep -R "9000" /etc/*
/etc/default/graylog-web:GRAYLOG_WEB_HTTP_PORT="9000"
/etc/init/graylog-web.conf:  GRAYLOG_WEB_HTTP_PORT="9000"

The script to launch the interface is in /etc/init/graylog-web.conf and calls the variable GRAYLOG_WEB_HTTP_PORT. You should be able to change these to 80 or 443 and restart the web-interface with

root@ubuntu14:~# service graylog-web restart

This should work. Let me know how it goes
