我正在遵循有关node.js的教程。本教程使用Express和Redis。我安装了redis和connect-

redis（在package.json中引用了它们）：

npm install redis connect-redis --save

在我的server.js中（仅是有意义的部分）：

var express = require('express');
var http = require('http');
var app = module.exports = express();
var RedisStore = require('connect-redis')(express);
var redis = require("redis").createClient();
app.configure(function(){
  app.set('port', process.env.PORT || 3000);
  app.set('views', __dirname + '/views');
  console.log('views', __dirname + '/views');
  app.set('view engine', 'jade'); //jade as template engine
  app.use(express.favicon());
  app.use(express.logger('dev'));
  app.use(express.bodyParser());
  app.use(express.methodOverride());
  app.use(express.cookieParser());
  app.use(express.session({
      secret: "kqsdjfmlksdhfhzirzeoibrzecrbzuzefcuercazeafxzeokwdfzeijfxcerig",
      store: new RedisStore({ host: 'localhost', port: 3000, client: redis })
  }));
  app.use(app.router);
  app.use(express.static(__dirname + '/public'));
});

错误信息：

Express server listening on port 3000 [ERROR] Error Error: Redis connection to 127.0.0.1:6379 failed - connect ECONNREFUSED at RedisClient.on_error (D:\Programming\Screencasts\peepcode\nodejs\peepcode -069-full-stack-nodejs-i-mov\code\roland\HotPie\node_modules\redis\index.js:140: 24) at Socket.<anonymous> (D:\Programming\Screencasts\peepcode\nodejs\peepcode-0 69-full-stack-nodejs-i-mov\code\roland\HotPie\node_modules\redis\index.js:74:14) at Socket.EventEmitter.emit (events.js:88:17) at Socket._destroy.self.errorEmitted (net.js:329:14) at process.startup.processNextTick.process._tickCallback (node.js:244:9) [ERROR] Error Error: Redis connection to 127.0.0.1:6379 failed - connect ECONNREFUSED at RedisClient.on_error (D:\Programming\Screencasts\peepcode\nodejs\peepcode -069-full-stack-nodejs-i-mov\code\roland\HotPie\node_modules\redis\index.js:140: 24) at Socket.<anonymous> (D:\Programming\Screencasts\peepcode\nodejs\peepcode-0

Express开始监听3000端口，这是我所期望的。redis错误消息提到端口6379上的连接。如果我将redisClient传递给RedisStore，就会发生这种情况，这是我理解的绑定redis和RedisStore的工作。
