New to MongoDB Can not run command mongo

Question

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.

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.
