如何讓我的應用程序連接到mongo db？

Question

我通過自制軟件安裝了mongodb，並遇到一些試圖連接數據庫的問題。

當我的mongod在終端上鍵入啓動服務器，一切似乎都很正常工作：然而，

new-host-4:~ scotty$ mongod 
all output going to: /usr/local/var/log/mongodb/mongo.log 

，當我嘗試使用nodemon我收到以下錯誤啓動服務器：

new-host-4:App scotty$ nodemon server.js 
15 May 12:25:23 - [nodemon] v0.7.8 
15 May 12:25:23 - [nodemon] to restart at any time, enter `rs` 
15 May 12:25:23 - [nodemon] watching: /Users/scotty/Documents/web_apps/App 
15 May 12:25:23 - [nodemon] starting `node server.js` 
    info - socket.io started 
connection error: [Error: failed to connect to [localhost:27017]] 

還包括啓動服務器，我嘗試在新的終端標籤運行蒙戈和我碰到下面的錯誤後：

new-host-4:~ scotty$ mongo 
MongoDB shell version: 2.4.3 
connecting to: test 
Wed May 15 12:28:11.123 JavaScript execution failed: Error: couldn't connect to server 127.0.0.1:27017 at src/mongo/shell/mongo.js:L112 
exception: connect failed 

我還包括mongolog我：

我有這個設置，而且對我的iMac電腦工作正常，但似乎無法得到它的工作在我的全新的MacBook。我怎樣才能解決這個問題？

您需要更改您的db文件夾的權限：/usr/local/var/mongodb/，或使用sudo運行mongod。
