我有一个问题,我的socketIO应用程序(用nodeJS制作)与我的mongoDB连接.我尝试连接远程服务器,但它会引发我的错误

这是我的代码(mongoDB中没有设置用户/密码):

   var url = "mongodb://192.168.1.5:27017/DB"

   MongoClient.connect(url, function(err, db) {
           console.log("test")
           if (!err) {
                   console.log("test");
           }
           else {
                   console.dir(err)
           throw err
           }
   //  db.close();
   });

这是当我启动服务器并尝试在导航器中启动应用程序时:服务器在端口80上侦听:

{ [MongoError: connect ECONNREFUSED] name: 'MongoError', message: 'connect ECONNREFUSED' }
/root/fys-realtime/examples/chat/node_modules/mongodb/lib/server.js:228
        process.nextTick(function() { throw err; })
                                            ^

背景资料

我正在玩我的第一个试图连接到远程mongodb的nodejs测试应用程序.

问题:

连接失败,并显示以下消息:

admin@testdev:~/Documents/nodejs_tests$ sudo nodejs index.js
Server has started.
Request for / received
About to route a request for: /
inside db connect method
Request for /favicon.ico received
About to route a request for: /favicon.ico
inside db connect method
MongoError: connect ECONNREFUSED
null
MongoError: connect ECONNREFUSED
null

这是连接的逻辑:

function connect_nimble() {
        console.log("inside db connect method");
        MongoClient.connect("mongodb://10.1.1.1:27017/test", function(err,db) {
                console.log(err);
                console.log(db);
                if(!err) {
                        console.log("booya!  Connected to mongo");
                        return true;
                }
        });
}

到目前为止我检查了什么:

1. 我确保数据库服务器正在使用端口27017.这是我在重启数据库时在mongodb日志中看到的内容:

   admin@mongotest:~$ tail -f /var/log/mongodb/mongod.log

我有那个代码：

var express = require('express'),
    stylus = require('stylus'),
    logger = require('morgan'),
    bodyParser = require('body-parser'),
    mongoose = require('mongoose');

var env = process.env.NODE_ENV = process.env.NODE_ENV || 'development';

var app = express();

function compile(str, path){
    return stylus(str).set('filename', path);
}

app.set('views', __dirname + '/server/views');
app.set('view engine', 'jade');
app.use(logger('dev'));
app.use(bodyParser.urlencoded({ extended: true }));
app.use(stylus.middleware(

            compile: compile

    ));
app.use(express.static(__dirname + '/public'));

mongoose.connect('mongodb://localhost/multivision');
var db = mongoose.connection;
db.on('error', console.error.bind(console, 'connection error..'));

    console.log('multivision db opened');
});

您好，我整整两天都在试图解决这个错误，谷歌搜索，阅读这里的相关论坛，但似乎我无法解决这个错误以使我的代码完全发挥作用。我将不胜感激任何帮助

第一位代表错误的描述，后面的位是代码。再次预先感谢您。
