MongoDB on a Windows 7 machine: No connection could be made

Question

After I have started Mongo using mongod.exe on a Windows 7 machine, I tried to start the mongo shell that failed with the error:

Failed to connect to

Answer 1

I was getting a similar error when I was trying to start my mongo db via cmd. However the difference was I had a config file which has the path to the db and log folders and wanted to use the same. I was using mongo few days back and it was running fine but when I started using it again today it was giving me the error :

2015-05-27T10:33:22.820-0400 I CONTROL  Hotfix KB2731284 or later update is   installed, no need to zero-out data files
MongoDB shell version: 3.0.2
connecting to: test

2015-05-27T10:33:23.857-0400 E QUERY    Error: couldn't connect to server 127.0.0.1:27017 (127.0.0.1), connection attempt failed at connect src/mongo/shell/mongo.js:179:14) at (connect):1:6 at src/mongo/shell/mongo.js:179 exception: connect failed

Here's how I fixed it :

1. Open cmd as admin and navigate to the bin folder of your MongoDB and type : mongod --config --install
2. Now start your mongo db service : net start mongodb you should get a message which says : The MongoDB service was started successfully.
3. close this command prompt and open another one as admin, navigate to the bin folder once again and type mongo

This will connect you to the mongodb test.

Press ctrl+c anytime to exit.

Hope this helps.
