I am giving a try to do a chat with Node.js and socket.io
Now here is my scenario I am using ubuntu 12.04 user and i have folder pp on desktop
inside that i am putted server file server.js
Here is the client:
$(document).ready(function() {
var urlServer = location.origin + ':8081';
var socket = io.connect(urlServer);
});
$(document).ready(function() {
var urlServer = location.origin + ':8081';
var socket = io.connect(urlServer);
$("#boton").on('click', function() {
var mensaje = $("#mensaje").val();
socket.emit("mensaje", {msg: mensaje});
});
socket.on("mensaje", function(msg) {
console.log("hemos recibido un mensaje", msg);
});
});
And here the server
var server = require('http').createServer(),
sio = require('socket.io'),
port = 8081;
server.listen(port);
var io = sio.listen(server, { log:true });
var channels = {};
io.sockets.on('connection', function (socket) {
console.log("Cliente conectado");
socket.on('mensaje', function (msg) {
console.log(msg);
socket.broadcast.emit('mensaje', msg);
});
});
console.log('1- Escuchando en http://localhost:' + port , "");
console.log("");
Now in the same folder I have an html file like
<!DOCTYPE html>
<html>
<head>
<script src="../jquery.js"></script>
<script src="../node_modules/socket.io/node_modules/socket.io-client/dist/socket.io"></script>
<script src="clientechat.js.js"></script>
<title>Chat con Node</title>
</head>
<body>
<div id="mensajes"></div>
<input type="text">
<input type="submit" id="boton">
</body>
</html>
when i am trying to run the app.js useing node like
node server.js
I am getting the error
warn - error raised: Error: listen EADDRINUSE
I try to restart all but it doesn't works
Please tell me what might I am doing wrong.

It means the address you are trying to bind the server to is in use. Do this;
Command:
ps -eaf|grep node
Output:
root 28029 27332 0 14:25 pts/2 00:00:03 node myVNC.js
This shows you the Process id where node is running, which in this case is "28029"
Now kill this process id using;
kill -9 28029
