MongoDB is a NoSQL Database (Document Store) server that we will be using throughout Code 301. In this step, we’ll be installing MongoDB on your system and preparing it for use.
MongoDB comes in 2 parts, a client and a server … the server runs constantly, waiting for clients to connect to it so that they can store and retrieve data. The server does the actual management of the data. You’ll get much deeper into the inner workings of these during your coursework.
The installation steps are slightly different if you’re running a Mac or Windows/Linux. Please follow the appropriate directions below.
Open your terminal, and run the following commands to install the MongoDB client and server.
This will take a short time to complete. Once it does, you’ll need to “start” the mongo database server so that we can make sure clients can connect.
brew tap mongodb/brew
brew install mongodb-community
After installation completes, run the following command to start the MongoDB Server:
brew services start mongodb-community
Note: Because of ongoing WSL2 changes, local install may not simply work. If this is the case, your instructor will have an online option they will share in class. If your MongoDB installation does not work after the first attempt, take a screen shot of the terminal to submit in place of the
mongoshvalidation (mentioned below), and move forward without local MongoDB installation.
Complete the following sections of Microsoft’s directions.
Once you have finished, run sudo service mongodb status and you should see the status of [ OK ] on the left side of the screen; if not, run sudo service mongodb start to start up the database server.
Run these commands, in order, to install MongoDB. Note that for this installation, we’ll be using apt instead of brew.
wget -qO - https://www.mongodb.org/static/pgp/server-5.0.asc | sudo apt-key add -
sudo apt-get install gnupg
echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/5.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-5.0.list
sudo apt-get update
sudo apt-get install -y mongodb-org
After installation completes, we’ll need to setup MongoDB as a “service” so that it can easily be restarted. Enter the following commands, in order, to set this up:
sudo curl -s https://raw.githubusercontent.com/mongodb/mongo/master/debian/init.d -o /etc/init.d/mongod
sudo chmod 755 /etc/init.d/mongod
sudo service mongod start
On Ubuntu Linux, mongo will now automatically restart on every reboot.
Now, let’s make sure we can connect to the MongoDB server. Run this command:
mongosh
You should see something similar to the following:
Current Mongosh Log ID: 63604c9f419a468d5c5fd283
Connecting to: mongodb://127.0.0.1:27017/?directConnection=true&serverSelectionTimeoutMS=2000&appName=mongosh+1.5.4
Using MongoDB: 6.0.0
Using Mongosh: 1.5.4
For mongosh info see: https://docs.mongodb.com/mongodb-shell/

The > at the bottom is what you’re really looking for. It’s a prompt that lets you know you are connected with the mongosh client to your running MongoDB server
Take a screen shot of your terminal when you type in mongosh. You will submit this screen shot along with your other computer set-up screen shots for this assignment.
Type exit to return to your bash shell. MongoDB is successfully installed.
