Mongodb:首次连接时无法连接到服务器

问题描述

我收到以下错误:

Warning { MongoError: failed to connect to server [mongodb:27017] on first connect
    at Pool.<anonymous> (/Users/michaelks/Desktop/users/node_modules/mongodb-core/lib/topologies/server.js:325:35)
    at emitOne (events.js:96:13)

    at process._tickCallback (internal/process/next_tick.js:98:9)
  name: 'MongoError',
  message: 'failed to connect to server [mongodb:27017] on first connect' }

即使我在运行Mongo的终端窗口中获​​得了此信息:

Even though I get this in the terminal window where I run Mongo:

2016-12-25T03:45:23.715+0100 I NETWORK [initandlisten] connection accepted from 127.0.0.1:58868 #8 (8 connections now open)

看起来好像有连接.

我都尝试过

$ mongod

和

$ brew services start mongo

这是我的test_helper.js

This is my test_helper.js

const mongoose = require('mongoose');
mongoose.connect('mongodb:localhost/users_test');
mongoose.connection
 .once('open', () => console.log('Good to go!'))
 .on('error', (error) => {
 console.warn('Warning', error);
 });

我还没有专门将数据库设置为"users_test"，因为我的印象是猫鼬或mongo或两者都将即时执行.

I have not specifically made the db "users_test" as I am under the impression that mongoose or mongo or both will do this on the fly.

我尝试了"localhost"和"127.0.0.1".我在OSX 10.11.5上我正在运行Node 7.3.0和Mongo 3.2.9

I've tried both "localhost" and "127.0.0.1​".I'm on OSX 10.11.5I'm running Node 7.3.0 and Mongo 3.2.9

我做错了什么?我如何找出问题所在?

What am I doing wrong? How do I figure out what's wrong?

推荐答案

要连接至mongodb与mongoose一起使用，可以使用:

To connect to mongodb with mongoose, you can use :

mongoose.connect('mongodb://localhost/users_test');

或

mongoose.connect('localhost/users_test');

或

mongoose.connect('localhost','users_test');

但不是mongoose.connect('mongodb:localhost/users_test');，它与正确的主机名(mongodb而不是localhost)不匹配

But not mongoose.connect('mongodb:localhost/users_test');, it doesnt match the right hostname (mongodb instead of localhost)
