If you didn’t detach it, then find it and stop it. If it’s detached you need to find its pid and kill it. I’m not sure what system you’re using; to see what’s running on port 3000 try: netstat -4np (linux) sockstat -4 (bsd) netstat -nb (windows - there’s probably a better way here, I don’t use windows for rails) Get the pid from the listing and kill it if it’s ok to do that. – Daniel B. ---
