Answer 1

ps -ef |grep node find app.js , kill pid of app.js

Answer 2

I have node red installed on my Mac and my Raspberry Pi. Had the exact same problem and doing 'killall' didn't help. Once I shut down the Raspberry Pi and restarted my computer it worked fine.

Answer 3

To kill node server first run this command in your terminal :

1. top
2. open another window then copy the server id from the previous window: PID number -9 kill so now you killed your node server try again to run your app.

Answer 4

suppose your server is running on port 3000

lsof -i tcp:3000
    COMMAND   PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
    node    11716 arun   11u  IPv6 159175      0t0  TCP *:3000 (LISTEN)

after that use kill -9 <pid>

in the above case sudo kill -9 11716

Answer 5

Run:

ps -ax | grep node

You'll get something like:

60778 ??         0:00.62 /usr/local/bin/node abc.js

Then do:

kill -9 60778

Answer 6

use below command to kill a process running at a certain port - 3000 in this example below

kill -9 $(lsof -t -i:3000)
