Port 18000 in source code vs port 8000

Hello, i found that in some file like common.py there are lines that defined port 18000.

LMS_BASE = 'localhost:18000'
LMS_ROOT_URL = "https://localhost:18000"

and it happens also in other files. Is it correct? because when we try to launch we use port 8000 for LMS. And I found that when I tried to sign up from studio.local.openedx.io:8001 i got it’s redirected to https://localhost:18000.

Should I change 18000 to 8000?

FYI I use sumac version,

@wowothk most of the other services and MFEs if you’re not using tutor currently expect the LMS to run on 18000 instead of the default django port of 8000. I would recommend using 18000 if you’re going to be running more services locally manually.

You can also use tutor which is a community supported version of the open edx platform that manages all the various port-mappings and such correctly for you.
