Node.js集群未响应Web浏览器

Question

I am a newbie in Nodejs and I try something with cluster on nodejs. But I meet a problem: - I use example on Nodejs API about Cluster:

var cluster = require('cluster');
var http = require('http');
var numCPUs = require('os').cpus().length;

if (cluster.isMaster) {
  // Fork workers.
  for (var i = 0; i < numCPUs; i++) {
    cluster.fork();
  }

  cluster.on('exit', function(worker, code, signal) {
    console.log('worker ' + worker.process.pid + ' died');
  });
} else {
  // Workers can share any TCP connection
  // In this case its a HTTP server
  http.createServer(function(req, res) {
    res.writeHead(200);
    res.end("hello world\n");
  }).listen(8000);
}

• I run above code, but when hit url into browser (localhost:8000), browser doesn't receive any response from nodejs (it's connecting... forever until I kill nodejs @@), I am,however, getting the "online" event to fire.

How can I get this server to respond to requests?

p/s: I try getting event "exit" to respawn new worker. Sometime when I hit enter on browser, console log worker x die and then respawn new worker. But browser still connecting...

I had a similar issue with cluster. Try putting the http server creation part inside a setTimeout call. (for example delay it for 1000 ms) you should observe an improvement.

setTimeout(function(){ http.createServer...... }, 1000);

Besides, you may also try to create your server using jxcore mt-keep to see if it works on the similar case.

$ jx mt-keep servercode.js
