我已经设置了npm,socket.io,redis和redis-server ...,但是我听不懂这个错误:
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)
代码:
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来启动Redis服务器。
