'Connection Error in Mongo DB in Windows

I am super new in doing MongoDB. Today is my first time doing it. The MongoDB is setup by someone else before that so I need some help here.

I tried starting mongo and this is the error:

C:\MongoDB>mongo
MongoDB shell version: 3.2.12
connecting to: test
2017-05-05T17:36:18.459+0800 W NETWORK  [thread1] Failed to connect to 
127.0.0.1
:27017 after 5000ms milliseconds, giving up.
2017-05-05T17:36:18.459+0800 E QUERY    [thread1] Error: couldn't connect to 
server 127.0.0.1:27017, connection attempt failed :
connect@src/mongo/shell/mongo.js:229:14@(connect):1:6

exception: connect failed

I also tried starting mongod.exe and there is error. Not sure if it's interlink or not.

I did see that data\db is created but just not in C:\ .In the config file, there is already a path written.

systemLog:
path: D:\MongoDB\mongod.log
storage:
dbPath: D:\mongod\data\db
mongodb

By default, mongod will attempt to use \data\db on the drive which you start MongoDB as its dbpath. In your case, that's C:\data\db.

If you'd like to start mongod as configured by the previous person (including access to its data), you need to provide option --config to mongod to point to the configuration file. This will set mongod to use the config file and run according to the setup provided (as configured by the previous person). i.e. using D:\data\db.

After add inbound rule for tcp 27017 port at firewall you should add the external IP Adress into config file, [mongod.cfg]

        # network interfaces
net:
  port: 27017
  bindIp: 127.0.0.1, add external ip here

I had that problem too. In my case, I start mongodb server first Here what i did

  • open cmd as administrative
  • type net start MongoDB
  • then type mongo

Hope this will solve your problem
