Question

i am trying to use node.js v0.8.2 and the cluster functionality to set up a web server on each core of my quad core machine

however i am stuck on a TypeError: Object is not a function, i am sure this is a simple error.

what am i doing wrong.

this is the code i am using

var cluster = require('cluster')
  , http = require('http');


var server = http.createServer(function(req, res){
  console.log('%s %s', req.method, req.url);
  var body = 'Hello World';
  res.writeHead(200, { 'Content-Length': body.length });
  res.end(body);
});

cluster(server)
  .use(cluster.logger('logs'))
  .use(cluster.stats())
  .use(cluster.pidfiles('pids'))
  .use(cluster.cli())
  .use(cluster.repl(8888))
  .listen(3000);

this is the erorr

F:\nodeJS\module\one.js:11
cluster(server)

Looks like you are over-complicating the use of cluster… try this instead:

var cluster = require('cluster')

if ( cluster.isMaster ) {
    for ( var i=0; i<2; ++i )
    cluster.fork();
} else {
    // includes for your app and app controller logic here  (just example using express, etc)
    ///////////////////
    // Server initiation
    ///////////////////
    var app = require('express').createServer(),
         redis = require("redis"), 
         Step = require("step"), 
         client = redis.createClient(siteConf.redisPort, siteConf.redisHost);

    // rest of your app here
}
