我知道我正在做一些非常愚蠢和愚蠢的事情，但是我希望有人可以帮助我建立从Mac上的node.js到mongodb的基本数据库连接。

我已经使用自制软件安装了mongodb，看起来效果很好。我已经以本地登录用户身份启动了服务器（mongod），并打开了第二个终端，并确认可以使用mongo连接到该服务器。当我运行mongo时，出现消息“正在连接：localhost：27017
/ test”，然后显示命令提示符。在mongo shell中运行一些命令，一切似乎都在那儿工作。左两个端子均打开并运行。

我还确认可以访问localhost：28017的Web界面。

我安装了node.js并添加了猫鼬包。现在尝试使用超级简单的node.js应用（也以本地登录用户身份运行）进行连接：

var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/test');

我收到以下错误

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: connect ECONNREFUSED
    at errnoException (net.js:901:11)
    at Object.afterConnect [as oncomplete] (net.js:892:19)

我的头撞在墙上，试图让事情变得如此简单。我想念什么？

编辑：这是mongod的日志。如您所见，我尝试了多次，但它们都瞬间失效：
