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]

开始失败但是当我只写mongod时说

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

然后在另一个控制台上我开始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]

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

并且在mongod控制台中它接受了连接

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.我无法理解我的mongo是否正在工作？（因为启动mongod总是失败但是在打字时只有mongod正在运行）

2.i无法通过我的robomongo连接到远程mongo服务器它说＆＃34;无法连接到mongodb＆＃34;

我的mongo.config文件 - ＆gt;

 # 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

    # Where and how to store data.
    storage:
      dbPath: /var/lib/mongo
      journal:
        enabled: true
    #  engine:
    #  mmapv1:
    #  wiredTiger:

    # how the process runs
    processManagement:
      fork: true  # fork and run in background
    #pidFilePath: /var/run/mongodb/mongod.pid  # location of pidfile

    # network interfaces
    net:

      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

回答你的问题：

如果可以使用mongo shell进行连接，则服务器正在运行。否则，您会看到Connection refused和exception: connect failed
默认情况下，AWS防火墙非常严格。请检查是否允许来自任何主机的端口27017的传入连接。会有一个警告说您正在向所有人开放端口，但是必须允许连接到数据库。

Answer 2

您的bindIp设置有点奇怪。为什么逗号分隔列表？只需使用0.0.0.0。

之后，在您的安全组中打开端口27017，您就可以连接。

与mongodb远程连接
