错误:Redis连接到127.0.0.1:6379失败 - 连接ECONNREFUSED

我已经设置了npm,socket.io,redis和redis-server ......但我无法理解这个错误:

throw er; // Unhandled 'error' event
      ^

Error: Redis connection to 127.0.0.1:6379 failed - connect ECONNREFUSED 127.0.0.
1:6379
    at Object.exports._errnoException (util.js:1016:11)
    at exports._exceptionWithHostPort (util.js:1039:20)
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1138:14)

码:

var app = require('express')();
var server = require('http').Server(app);
var io = require('socket.io')(server);
var redis = require('redis');

server.listen(8890);

io.on('connection', function (socket) {     
    console.log("client connected");
    var redisClient = redis.createClient();
    redisClient.subscribe('message');

    redisClient.on("message", function(channel, data) {
        console.log("new message add in queue "+ data['message'] + " channel");
        socket.emit(channel, data);
    });

    socket.on('disconnect', function() {
        redisClient.quit();
    }); 
});

    redis.createClient()尝试连接到本地计算机的redis服务器并尝试使用端口号6379.为此,您需要使用以下命令启动redis服务器 .

    redis-server
