Answer 1

All you need to do is open 2 terminal tabs. In one, run

mongod

which starts the MongoDB server.

In the other, run

mongo

which is the shell that connects to your MongoDB server.

Answer 2

It looks like MongoDB isn't running. Can you connect to the web interface in your browser?

http://localhost:28017

Also, do you see the process running on your machine? You should see an entry for mongod when running ...

$ top

or

$ ps aux
