If you are getting these type of errors when running mongod from command line or running mongodb server, enter image description here
then follow these steps,

  1. Create db and log directories in C: drive
    C:/data/db and C:data/log
  2. Create an empty log file in log dir named mongo.log
  3. Run mongod from command line to run the mongodb server or create a batch file on desktop which can run the mongod.exe file from your mongodb installation direction. That way you just have to click the batch file from your desktop and mongodb will start.
  4. If you have 32-bit system, try using --journal with mongod command.

  1. Go to C:\Program Files\MongoDB\Server\3.4\bin using cmd and write mongod.
  2. Open another cmd by right click and run as admin point to your monogodb installed directory as mentioned above and then just like write this mongo.exe
  3. After that, write db.test.save({Field:'Hello mongodb'}) this command will insert a field having name Field and value is Hello mongodb.
  4. After, check the record db.test.find() and press enter you will find the record that you have recently entered.

Create default db folder.

c:\data\db

and also log folder

c:\data\log\mongo.log

or use following commands in command-prompt

mkdir c:\data\log    
mkdir c:\data\db

For this error, if you are using windows 7 or windows server 2008 R2, the problem could be that you have to install a microsoft hotfix.

Did you create the default db path?
It defaults to "/data/db directory (or c:\data\db on Windows)"

  1. Create default db folder.

    c:\data\db

    and also log folder

    c:\data\log\mongo.log

    or use following commands in command-prompt

    mkdir c:\data\log    
mkdir c:\data\db

  2. Create config file in bin folder of mongo (or you may in save your desired destination).

    Add following in text file named "mongod" and save it as
    mongod.cfg
    dbpath=c:\data\db
    logpath=c:\data\log\mongo.log

    or use following commands in command-prompt

    echo dbpath=c:\data\db>> "mongod.cfg"
echo logpath=c:\data\log\mongo.log>> "mongod.cfg"

  3. Now open command-prompt (administrator) and run the following command to start mongo server

    mongod

  4. Open another command-prompt (don't close 1st prompt) and run client command:

    mongo

Hope this will help or you have done this already.

The error occurs when trying to run mongo.exe WITHOUT having executed mongod.exe. The following batch script solved the problem:

@echo off
cd C:\mongodb\bin\
start mongod.exe
start mongo.exe
exit

you can use below command,

mongod --dbpath=D:\home\mongodata

where D:\home\mongodata is the data storage path

I found that when I got this error it wasn't because I didn't have my default db path set up. It was because I was trying to run mongo.exe before running mongod.exe.
