//Run this command to get the PID of the running
ps aux | grep node
//Then kill/stop it by
kill -9 PID

First, you would want to know which process is using port 8081
sudo lsof -i :8081
this will list all PID listening on this port, once you have the PID you can terminate it with the following:
kill -9 {PID} (in my case it was the 5182)

//To find the process id (PID) associated with the port
lsof -i tcp:3000
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
node 44475 chen5 31u IPv4 0x8b1721168764e4bf 0t0 TCP *:strexec-s (LISTEN)
//Then to kill the process
kill -9 44475

Find server pid:
lsof -i tcp:5000 (the 5000 is the port number)
kill the server:
kill -9 111119 (the 111119 is the pid)
