与mongodb的远程连接

Question

我已经通过官方文档在亚马逊的linux环境中安装mongodb。

安装后，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] 

启动失败，但是当我只写的mongod是说

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

，然后另一台主机上，我开始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]

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

和在mongod控制台它接受了连接

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

现在我有几个问题，

1.I我不能够理解我的蒙戈是工作或没有？ （东阳开始的mongod总是失败，但上键入唯一的mongod工作）

2.我无法通过我的robomongo连接到远程服务器蒙哥它说：“无法连接到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.

     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设置有点怪异。为什么用逗号分隔列表？只需使用0.0.0.0。

之后，打开安全组中的端口27017，您将能够连接。

Answer 2

回答您的问题：

1. 如果能够连接使用mongo外壳，然后服务器正在运行。否则，您将看到类似Connection refused和exception: connect failed和exception: connect failed的错误

2. 默认情况下，AWS防火墙的限制性很强。请检查您是否允许从任何主机到端口27017的传入连接。将会有一个警告声明您正在向所有人开放端口，但有必要允许连接到数据库。
