“Express.js集群”的版本间的差异

2012年12月4日 (二) 06:48的版本

express.js利用cluster模块做集群

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

   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(app).listen(app.get('port'), function(){
           console.log("Express server listening on port " + app.get('port'));
       });
   }
