MongoDB Tutorial - 3 - Installation

Once you have that all set up you'll want to open a couple of command prompts. And I usually will have one open and then type start cmd.exe.

In order to get the local instance of mongodb running you will use the command 'mongod' M-O-N-G-O-D. You may need to navigate into the bin folder I showed you earlier and from there type mongod.

And this will give us access to our mongo shell. So in order to use our shell or run applications locally that use mongodb, we need to have mongod running.

Then, in another terminal I can use the command 'mongo' M-O-N-G-O to open up the shell.

The first thing I want to do is add I new collection to my example database and name it cars. And I can do that using the create Collection command. Whenever we're using our mongo shell to execute commands and hook up to one of our databases, we always use the prefix db dot.

And now I want to show you some of the most common commands when using the shell.

So I can say DB dot the name of my collection I want to look at. We'll start with Things dot find. We can see that there is one document in this collection. Which has an underscore ID key who's value is set to an ObjectID - And this gets automatically generated every time a new document is created. The document includes One object with a name of Will.
