Mongo server

Start the MongoDB server as a “daemon” background process.

$ mongod

Or configure it to run as a background service on your machine.

See the Installation instructions on the Mongo docs for your OS for parameters to use.

The manual commands are also specific to OS and chip, so are not covered here.

MongoDB shell

See mongosh docs.

The MongoDB shell is an interactive JavaScript interface that allows you to interact with MongoDB databases, collections, and documents.

If the server above is running, you can start without parameters:

$ mongosh

For a cloud deployment, you can use connection string. Example based on the docs:

$ mongosh "mongodb+srv://mycluster.abcd1.mongodb.net/myFirstDatabase" --apiVersion 1 --username <username>

Then use the help command in the interactive shell for commands. See also the Basic operations cheatsheet.
