使用mongoose.connect（）連接到MongoDB實例在EC2上

我的應用程序正在試圖建立到MongoDB的EC2上使用下面的命令連接：使用mongoose.connect（）連接到MongoDB實例在EC2上

mongoose.connect("mongodb://username:[email protected]:27017/databasename")

我有口27017和28017打開服務器。爲了驗證我也打開了所有的流量，這不是一個好主意。

我也能夠通過蒙戈沒有問題連接：

mongo admin --username username -p --host ec2-xx-xxx-x-xxx.us-west-2.compute.amazonaws.com --port 27017

當我運行應用程序，我得到以下錯誤：

process.nextTick(function() { throw err; });

我看到2個可能的問題：1 - 您的用戶名：密碼未在應用程序中設置。 2 - 你有一個用戶設置爲數據庫名？默認情況下，除非明確設置，否則不需要用戶連接到數據庫 –

看來你沒有創建一個用戶嘗試連接的數據庫。我將使用管理員用戶連接MongoDB並創建它：

mongo admin --username root --password rootpassword --host ec2-xx-xxx-x-xxx.us-west-2.compute.amazonaws.com --port 27017 

MongoDB shell version: XXX 
connecting to: x.x.x.x:27017/admin 

> db = db.getSiblingDB('databasename') 
databasename 
> db.createUser({ user: "username", pwd: "password", roles: [ "readWrite", "dbAdmin" ]}) 
{ 
"user" : "username", 
"pwd" : "...", 
"roles" : [ 
    "readWrite", 
    "dbAdmin" 
], 
"_id" : ObjectId("...") 
} 
> exit
