laravel - Redis 连接到 127.0.0.1 :6379 failed - connect ECONNREFUSED In laravel

Question

当我运行 node serve.js 时，出现以下错误

   throw er; // Unhandled 'error' event
   ^

 Error: Redis connection to 127.0.0.1:6379 failed - connect ENFILE 127.0.0.1:6379 - Local (undefined:undefined)
at Object.exports._errnoException (util.js:1018:11)

at process._tickCallback (internal/process/next_tick.js:104:9)

Server.js 文件

  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("mew message add in queue "+ data['message'] + " channel");
   socket.emit(channel, data);
 });

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

 });

我该如何解决以上错误。我已经安装了 node、npm、predis 和 socet.io

我遇到了同样的问题，但我通过安装 redis 并先前在终端中执行它解决了它。

如果您使用的是 mac，您可以使用以下命令通过 brew 轻松安装 redis:

brew install redis

安装后运行以下命令:

redis-serve
