I was trying to run MongoDB:

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)?

Answer 1

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.
