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) {
socket.end("Hello!\n");
});
server.listen(7777);
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:
node.js:201
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?
Solution 1:
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.

Solution 2:
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
Solution 3:
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.
