Installing MongoDB - MongoDB Basics - page 24

Once you create the required directory and assign the appropriate permissions,
you can start the MongoDB core database service by executing the mongod application.
You can do this from the command prompt or the shell in Windows and Linux, respectively.

Surveying the Installation Layout
After you install or extract MongoDB successfully, you will have the applications shown in
Table 2-1 available in the bin directory (in both Linux and Windows).

The installed software includes 15 applications (or 14, under Microsoft Windows)
that you will be using in conjunction with your MongoDB databases. The two “most
important” applications are the mongo and mongod applications. The mongo application
allows you to use the database shell; this shell enables you to accomplish practically
anything you'd want to do with MongoDB.
