Simple multi-CPU cluster server manager for Node 0.6+

Install

npm i cluster-server

Usage

    // require('cluster-server')(port, host, cb);
    // port defaults to 8888, host defaults to "0.0.0.0"
    require('cluster-server')(function() {
      var express = require('express');
      var app = express.createServer();
      app.get('/', function(req, res) {

Description

This module pre-forks several workers, calls the supplied function in each of the workers, and pings each worker every second to restart any workers that were stuck or terminated.

The number of workers is require('os').cpus().length, with a minimum of 3 and a maximum of 6.

It also handles INT, TERM, KILL and QUIT signals and terminates the workers accordingly. However, setsid(1) is still recommended so workers can terminate when the master is killed by an non-catchable signal.

(Same idea, but without polling for "stuck" workers)
