Stop node.js program from command line


I have a simple TCP server that listens on a port.

var net = require("net");

var server = net.createServer(function(socket) {


I start it with node server.js and then close it with Ctrl + Z on Mac. When I try to run it again with node server.js I get this error message:

        throw e; // process.nextTick error, or 'error' event on first tick
Error: listen EADDRINUSE
at errnoException (net.js:670:11)
at Array.0 (net.js:771:26)
at EventEmitter._tickCallback (node.js:192:41)

Am I closing the program the wrong way? How can I prevent this from happening?

To end the program, you should be using Ctrl + C. If you do that, it sends SIGINT, which allows the program to end gracefully, unbinding from any ports it is listening on.

I ran into an issue where I have multiple node servers running, and I want to just kill one of them and redeploy it from a script.

Note: This example is in a bash shell on Mac.

To do so I make sure to make my node call as specific as possible. For example rather than calling node server.js from the apps directory, I call node app_name_1/app/server.js

Then I can kill it using:

kill -9 $(ps aux | grep 'node\ app_name_1/app/server.js' | awk '{print $2}')

This will only kill the node process running app_name_1/app/server.js.

If you ran node app_name_2/app/server.js this node process will continue to run.

If you decide you want to kill them all you can use killall node as others have mentioned.

you can type .exit to quit node js REPL

If you are running Node.js interactively (the REPL):

Ctrl + C will take back you to > prompt then type:


or just use Ctrl + D.

Resume and kill the process:

Ctrl+Z suspends it, which means it is still running as a suspended background process.

You are likely now at a terminal prompt...

  1. Give the command fg to resume the process in the foreground.

  2. type Ctrl+C to properly kill it.

Alternatively, you can kill it manually like this:

(NOTE: the following commands may require root, so sudo ... is your friend)

pkill -9 node

or, if you don't have pkill, this may work:

killall node

or perhaps this:

kill $(ps -e | grep node | awk '{print $1}')

sometimes the process will list its own grep, in which case you'll need:

kill $(ps -e | grep dmn | awk '{print $2}')


h/t @ruffin from the comments on the question itself. I had the same issue and his comment helped me solve it myself.

Ctrl+Z suspends it, which means it can still be running.

Ctrl+C will actually kill it.

you can also kill it manually like this:

ps aux | grep node

Find the process ID (second from the left):

kill -9 PROCESS_ID

This may also work

killall node

Though this is a late answer, I found this from NodeJS docs:

The 'exit' event is emitted when the REPL is exited either by receiving the .exit command as input, the user pressing <ctrl>-C twice to signal SIGINT, or by pressing <ctrl>-D to signal 'end' on the input stream. The listener callback is invoked without any arguments.

So to summarize you can exit by:

  1. Typing .exit in nodejs REPL.
  2. Pressing <ctrl>-C twice.
  3. pressing <ctrl>-D.
  4. process.exit(0) meaning a natural exit from REPL. If you want to return any other status you can return a non zero number.
  5. process.kill( is the way to kill using nodejs api from within your code or from REPL.

I'm adding this answer because for many projects with production deployments, we have scripts that stop these processes so we don't have to.

A clean way to manage your Node Server processes is using the forever package (from NPM).


Install Forever

npm install forever -g

Run Node Server

forever start -al ./logs/forever.log -ao ./logs/out.log -ae ./logs/err.log server.js


info: Forever processing file: server.js

Shutdown Node Server

forever stop server.js


info: Forever stopped process: uid command script forever pid id logfile uptime [0] sBSj "/usr/bin/nodejs/node" ~/path/to/your/project/server.js 23084 13176 ~/.forever/forever.log 0:0:0:0.247

This will cleanly shutdown your Server application.

Or alternatively you can do all of these in one line:

kill -9 $(ps aux | grep '\snode\s' | awk '{print $2}')

You can replace node inside '\snode\s' with any other process name.

If you want to stop your server with npm stop or something like this. You can write the code that kill your server process as:

require('child_process').exec(`kill -9 ${pid}`)

$ sudo killall node in another terminal works on mac, while killall node not working:

$ killall node
