NodeJs - 使用redis，connect-redis与express [英] NodeJs - Using redis, connect-redis with express

问题描述

注意
对于那些与Redis挣扎的人，Redis服务器必须启动。在Windows上，有一个redis发行版，请查看以下链接： https://github.com/dmajkic/ redis / downloads 然后启动服务器启动redis-server.exe

NOTE For those struggling with Redis, the Redis server has to be launched. On windows, there is a redis distribution, check out the following link: https://github.com/dmajkic/redis/downloads then start the server by launching "redis-server.exe"

我正在关于node.js上的教程。本教程使用Express和Redis。
我安装了redis和connect-redis（它们在package.json中引用）：

I am following along a tutorial on node.js. The tutorial uses Express and Redis. I installed redis and connect-redis (they are referenced in package.json):

npm install redis connect-redis --save

在我的server.js（只有意义的部分）：

In my server.js (only meaningful part):

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

Express开始侦听端口3000，这是我期望的。redis错误消息提到端口6379上的连接。如果我将redisClient传递给RedisStore，这是我理解的要绑定redis和RedisStore的情况。

Express starts listening on port 3000, which is what I expect. The redis error message mentions connection on port 6379. This happens if I pass the redisClient to RedisStore, which is what I understood to do to bind redis and RedisStore.

我正在Windows上开发

推荐答案

看起来你没有redis您对 redis.io/download 有关如何下载，安装和运行服务器的一个很好的解释和客户端。

It looks like you don't have the redis server running. You have a good explanation on redis.io/download about how to download, install it and run both server and client.
