setting_detail = {};
process.env.NODE_ENV = process.env.NODE_ENV || 'development';
if (process.env.NODE_ENV == 'production') {
var cluster = require('cluster');
if (cluster.isMaster) {
// Count the machine's CPUs
var cpuCount = require('os').cpus().length;
// Create a worker for each CPU
for (var i = 0; i < cpuCount; i += 1) {
cluster.fork();
}
// Code to run if we're in a worker process

You just need to run node server.jsat your project path & then visit this -http://localhost:5000
你只需要node server.js在你的项目路径上运行然后访问这个 - http://localhost:5000
