pm2가 실행되고 있는 것 아닌가요?
npx pm2 list
pm2가 실행되고 있으면 서버를 꺼도 pm2가 다시 되살립니다. pm2가 실행되고 있는 상태에서는 pm2를 종료(npx pm2 kill)하고 다시 시작하든지 아니면 npx pm2 reload all로 재부팅만 하면 됩니다.

포트 끄기 명령어로 포트를 꺼도 포트가 계속 다른 번호로 검색되여 포트가 자동으로 실행되고 있는걸까여?

이미 80번 포트에 서버를 실행했는데 그걸 끄지않고 하나더 실행하려고 하신 것 같습니다.
lsof -i tcp:80 으로 80번 포트를 사용하는서비스의 프로세스아이디를 찾고
kill -9 프로세스아이디
하면 꺼집니다.
