Error listen EADDRINUSE while using nodejs

0 votes

If I run a server with the port 80, and I try to use xmlHTTPrequest i get this error: Error: listen EADDRINUSE

Why is it problem for nodejs, if I want to do a request, while I run a server on the port 80? For the webbrowsers it is not a problem: I can surf on the internet, while the server is running.

The server is:

  net.createServer(function (socket) {
    socket.name = socket.remoteAddress + ":" + socket.remotePort;
    console.log('connection request from: ' + socket.remoteAddress);
    socket.destroy();
  }).listen(options.port);

And the request:

var xhr = new XMLHttpRequest();

xhr.onreadystatechange = function() {
    sys.puts("State: " + this.readyState);

    if (this.readyState == 4) {
        sys.puts("Complete.\nBody length: " + this.responseText.length);
        sys.puts("Body:\n" + this.responseText);
    }
};

xhr.open("GET", "http://mywebsite.com");
xhr.send();

Hello kartik,

Two possible solutions for this:

  1. Free currently used port number
  2. Select another port number for your current program

Your application is already running on that port 8080 . 

Use this code to kill the port and run your code again

sudo lsof -t -i tcp:8080 | xargs kill -9

Hope this works!!

Thank You!!
