Is it possible to access the azerothcore game console vis SSH while the worldserver is being run by systemctl?

I'm a longtime Windows admin and I'm trying to learn my way around Linux, but I just set up a service using systemctl to run worldserver and authserver so that I don't have to keep the PuTTY windows open on my computer 24/7. It's been working fine but I'd like to be able to SSH to the game server using PuTTY to quickly enter commands instead of having to launch the game and login to my GM character.

When I connect to the game server, I don't have the AC> prompt since I didn't run the ./worldserver command in that session, and I'm not sure if I can just run ./worldserver in my PuTTY session while it's simultaneously being run by systemctl without breaking things.

Solution

You can use screen to reattach to your server console while running from a service. To install screen on Debian/Ubuntu:

sudo apt install screen

Change your service file to start a screen session:

ExecStart=/bin/screen -S worldserver -D -m /path/to/azerothcore/bin/worldserver

Reload the services configuration (sudo systemctl daemon-reload)
Restart your worldserver service (sudo systemctl restart your-world-server.service)
Run screen -r worldserver to attach to the session
You can now type commands in your world console
Press ctrl+a then d to detach from the session
