Creating a MongoDB database

First create a directory for the database and set permissions:

$ mkdir /data/db
$ sudo chown -R `id -un` /data/db

Then start the Mongo daemon

mongod

This will run continuously in the terminal and should say somewhere that it is waiting for connections on port 27017. This command must be executed before you run any backend that interacts with the Mongo database.

MongoDB Compass

Compass is a graphical interface for viewing and interacting with the data in your Mongo database. It will automatically load to the default Mongo port: 27017.
