I was looking at http://www.mongodb.org/display/DOCS/Quickstart+Windows and following the instructions. Could anyone tell me what is the problem with running MongoDB (I am using Windows 7)?

Windows Solutions

Solution 1 - Windows

After installing the MongoDB you should manually create a data folder.

By default MongoDB will store data in /data/db, but it won't automatically create that directory. To create it, do:

$ sudo mkdir -p /data/db/ $ sudo chown id -u /data/db

You can also tell MongoDB to use a different data directory, with the --dbpath option.

For more detailed information go to MongoDB wiki page.

Solution 2 - Windows

I think your log output states it clearly;

exception in initAndListen: 10296 dbpath (/data/db) does not exist, terminating

You may simply create this directory or better to define it as a configuration value within your configuration file then use it as mongod -f C:\path\to\your\mongodb.conf.

Solution 3 - Windows

Specify the database path explicitly like so, and see if that resolves the issue.

mongod --dbpath data/db

Solution 4 - Windows

mongod --dbpath "c://data/db"

run the above code, this will start the server.

Solution 5 - Windows

For Windows 7

You may specify an alternate path for \data\db with the dbpath setting for mongod.exe,

as in the following example:

c:\mongodb\bin\mongod.exe --dbpath c:\mongodb\data\db

you can set dbpath through Configuration File.

Solution 6 - Windows

Check that path to database data files exists ;) :

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

Solution 7 - Windows

This worked for me (if it applies that you also see the lock file):

first>youridhere@ubuntu:/var/lib/mongodb$ sudo service mongodb start 
then >youridhere@ubuntu:/var/lib/mongodb$ sudo rm mongod.lock*

Solution 8 - Windows

After several attempts this works for me on Windows 7 env.:

Initially directory to which you have copied all MongDB sources has such view:

bsondump.exe
mongo.exe
mongod.exe
mongod.pdb
mongodump.exe
mongoexport.exe
mongofiles.exe
mongoimport.exe
mongooplog.exe
mongoperf.exe
mongorestore.exe
mongos.exe
mongos.pdb
mongostat.exe
mongotop.exe

All you need is to add data directory and db directory nested( data/db ) Final view should look like this:

data
bsondump.exe
mongo.exe
mongod.exe
mongod.pdb
mongodump.exe
mongoexport.exe
mongofiles.exe
mongoimport.exe
mongooplog.exe
mongoperf.exe
mongorestore.exe
mongos.exe
mongos.pdb
mongostat.exe
mongotop.exe

Than simply type in directory where MongoDB sources and data/db dirs exist this command:

C:\my_mongo_dir\bin>mongod --dbpath .\data\db

Solution 9 - Windows

Create the data/db directory in your main (windows) partition:

C:\> mkdir \data
C:\> mkdir \data\db

and then go to your mongo_directory/bin and run mongod.exe:

C:\> cd \my_mongo_dir\bin

C:\my_mongo_dir\bin> mongod

DON't CLOSE THIS WINDOW

Now in a different command prompt window run Mongo:

C:\> cd \my_mongo_dir\bin
C:\my_mongo_dir\bin> mongo

(REMEMBER YOU HAVE TO KEEP THAT OTHER WINDOW OPEN)

This solved the problem for me.

Solution 10 - Windows

Also check if you have installed the Mongo as a windows service and if its running. That's also important. There might port conflict because of that.

Solution 11 - Windows

create folder structure data/db in the working directory and then starting up mongodb using "mongod --dbpath data/db" works just fine

Solution 12 - Windows

You should create a startup.bat if you're using Windows, much more convenient:

C:\mongodb\mongodb-win32-x86_64-eiditon\bin\mongod.exe --dbpath C:\mongodb\data

And just dbclick startup.bat and mongodb will run using C:\mongodb\data as its data folder.

Solution 13 - Windows

You just need to create directory in C:. as C:\data\db\

Now just start mongoDB:

C:\Users\gi.gupta>"c:\Program Files\MongoDB\Server\3.2\bin\mongod.exe"

It will then run as service in background.

Solution 14 - Windows

If you're using Windows 7/ 7+.

Here is something you can try. >Check if the installation is proper in CONTROL PANEL of your computer.

Now goto the directory and where you've install the MongoDB. Ideally, it would be in

>C:\Program Files\MongoDB\Server\3.6\bin

Then either in the command prompt or in the IDE's terminal. Navigate to the above path ( Ideally your save file) and type

>mongod --dbpath

It should work alright!

Solution 15 - Windows

The very simplest approach given by mongo README help file

RUNNING

For command line options invoke:

$ ./mongod --help

To run a single server database:

$ sudo mkdir -p /data/db
$ ./mongod
$
$ # The mongo javascript shell connects to localhost and test database by default:
$ ./mongo
> help

If you are working with windows, go to your directory where you have mongo.exe

use the following commands, (I am sharing mine)

C:\Program Files\MongoDB\Server\3.6\bin>mkdir \data

C:\Program Files\MongoDB\Server\3.6\bin>mkdir \data\db

C:\Program Files\MongoDB\Server\3.6\bin>mongod ## this will start your mongoDB server

Now you need to run another CMD prompt and go to the directory where you have mongo and just run it

C:\Program Files\MongoDB\Server\3.6\bin>mongo ## this will start your mongoDB client

Hope it helped :)

If it doesn't work, run CMD as an administrator
