Changing Node js listening port

Question

I just installed node js on Windows  I have this simple code which does not run   I get  Error  listen EADDRINUSE  Is there a config file that tells node js to listen on a specific port   The problem is I have Apache listening on port 80 already   EDIT   var http   require  http     var url   require  url      http createServer function  req  res      console log  Request      req method     to     req url     res writeHead 200   OK      res write   lt h1 gt Hello lt  h1 gt Node js is working      res end        listen 5454    console log  Ready on port 5454

I usually manually set the port that I am listening on in the app.js file (assuming you are using express.js

var server = app.listen(8080, function() {
    console.log('Ready on port %d', server.address().port);
});

This will log Ready on port 8080 to your console.

you can get the nodejs configuration from http   nodejs org   The important thing you need to keep in your mind is about its configuration in file app js which consists of port number host and other settings these are settings working for me   backendSettings      scheme   https   http     host   Your website url    port  49165    port number   sslKeyPath    Path for key    sslCertPath    path for SSL certificate    sslCAPath        resource    socket io    baseAuthPath     nodejs     publishUrl   publish    serviceKey       backend     port  443   scheme    https   http     whatever is your website scheme  host   host name    messagePath    nodejs message      clientsCanWriteToChannels  false   clientsCanWriteToClients  false   extensions       debug  false   addUserToChannelUrl    user channel add  channel  uid    publishMessageToContentChannelUrl    content token message    transports    websocket    flashsocket    htmlfile    xhr-polling    jsonp-polling     jsMinification  true   jsEtag  true   logLevel  1    In this if you are getting  Error  listen EADDRINUSE  then please change the port number i e  here I am using  49165  so you can use other port such as 49170 or some other port  For this you can refer to the following article  http   www a2hosting com kb installable-applications manual-installations installing-node-js-on-shared-hosting-accounts

There is no config file unless you create one yourself   However  the port is a parameter of the listen   function   For example  to listen on port 8124   var http   require  http    http createServer function  req  res      res writeHead 200    Content-Type    text plain       res end  Hello World n       listen 8124   127 0 0 1    console log  Server running at http   127 0 0 1 8124       If you re having problems finding a port that s open  you can go to the command line and type   netstat -ano   To see a list of all ports in use per adapter
