MongoDB Setup Guide

Follow this guide to set up your MongoDB environment for this class.

1. Start up your Jupyter notebook instance and open a terminal window. Run the following commands in the terminal:
   
2. wget -qO - https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add -
   
3. sudo apt-get install gnupg
   
4. wget -qO - https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add -
   
5. echo "deb http://repo.mongodb.org/apt/debian buster/mongodb-org/4.4 main" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list
   
6. sudo apt-get update
   
7. sudo apt-get install -y mongodb-org
   

Note: #5 == a single command (i.e. /etc/apt/sources.list.d/mongodb-org-4.4.list is a parameter to tee).

Start up MongoDB (mongod service):
8. sudo systemctl start mongod
9. sudo systemctl status mongod
10. sudo systemctl enable mongod

Start using Mongo via the mongo shell:
11. mongo

Expected output:

Welcome to the MongoDB shell.
For interactive help, type "help".

12. db
13. use mydb
14. db.mycoll.insertOne({ x: 1, y: 2, z: "hi" })
15. show collections
16. db.mycoll.find()
