With the help of the following code, I was trying to run MongoDB

   E:\mongo\bin>mongod

    mongod --help for help and startup options

    Sun Nov 06 18:48:37

    Sun Nov 06 18:48:37 warning: 32-bit servers don't have journaling enabled by default. Please use --journal if you want durability.

E:\mongo\bin>mongo

MongoDB shell version: 2.0.1

connecting to: test

Sun Nov 06 18:48:42 Error: couldn't connect to server 127.0.0.1 shell/mongo.js:84

exception: connect failed

E:\mongo>ls

GNU-AGPL-3.0  README THIRD-PARTY-NOTICES  bin data

I was looking at the official document of MongoDB and followed the instructions. Why the error is coming while running MongoDB btw I am using Windows 7?

You are getting the following error:

Sun Nov 06 18:48:37 [initandlisten] exception in initAndListen: 10296 dbpath (/data/db) does not exist, terminating

Which means that you have to create the directory, you are missing the directory in your data folder. Inside the data folder, create a folder named db. Inside this db folder, all your databases will get stored. 

If you are a beginner and want to know more about MongoDB then refer to the following MongoDB tutorial which will help you to learn MongoDB from scratch.
