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).
