與mongodb的遠程連接

Question

我已經通過官方文檔在亞馬遜的linux環境中安裝mongodb。

安裝後，我做了

[root@ip-172-31-20-51 etc]# service mongod restart 
dirname: missing operand 
Try 'dirname --help' for more information. 
Stopping mongod:           [ OK ] 
Starting mongod:           [FAILED] 

啓動失敗，但是當我只寫的mongod是說

[root@ip-172-31-20-51 etc]# mongod

，然後另一臺主機上，我開始mongo

[root@ip-172-31-20-59 etc]# mongo 
MongoDB shell version: 3.2.9 
connecting to: test 
Server has startup warnings: 
2016-09-21T05:23:57.905+0000 I CONTROL [initandlisten] ** WARNING: You are running this process as the root user, which is not recommended.

2016-09-21T05:23:57.905+0000 I CONTROL [initandlisten]

和在mongod控制檯它接受了連接

2016-09-21T05:25:09.684+0000 I NETWORK [initandlisten] connection accepted from 127.0.0.1:49068 #1 (1 connection now open) 

現在我有幾個問題，

1.I我不能夠理解我的蒙戈是工作或沒有？ （東陽開始的mongod總是失敗，但上鍵入唯一的mongod工作）

2.我無法通過我的robomongo連接到遠程服務器蒙哥它說：「無法連接到MongoDB的」

我mongo.config文件 - >

# mongod.conf 

    # for documentation of all options, see: 
    # http://docs.mongodb.org/manual/reference/configuration-options/ 

    # where to write logging data. 
    systemLog: 
     destination: file 
     logAppend: true 
     path: /var/log/mongodb/mongod.log

    # network interfaces

     bindIp: 0.0.0.0,10.0.0.1,127.0.0.1 # Listen to local interface only, comment to listen on all interfaces. 

Answer 1

你的bindIp設置有點怪異。爲什麼用逗號分隔列表？只需使用0.0.0.0。

之後，打開安全組中的端口27017，您將能夠連接。

Answer 2

回答您的問題：

1. 如果能夠連接使用mongo外殼，然後服務器正在運行。否則，您將看到類似Connection refused和exception: connect failed和exception: connect failed的錯誤

2. 默認情況下，AWS防火牆的限制性很強。請檢查您是否允許從任何主機到端口27017的傳入連接。將會有一個警告聲明您正在向所有人開放端口，但有必要允許連接到數據庫。
