1. Introduction

In this tutorial, we are going to learn how to install MongoDB on different platforms. MongoDB is a source-available cross-platform document-oriented database program. It is classified as a NoSQL database program, and uses JSON-like documents with optional schemas.

By the end of this tutorial, you will be able to install and setup MongoDB on Windows, macOS, and Linux.

Prerequisites: Basic knowledge of command line interface is recommended.

2. Step-by-Step Guide

Installing MongoDB on Windows

1. Download the MongoDB installer

Visit the MongoDB official website and download the MongoDB Community Server. Choose the version that is appropriate for your Windows system (Windows Server 2008 R2, Windows 7, and later).

1. Run the MongoDB installer

After the download is complete, execute the installer. Follow the prompts in the installation wizard.

1. Set MongoDB Environment Variable

To use MongoDB from anywhere on your system, you'll need to add the path of your MongoDB server to your system environments PATH variable. You can find this usually under C:\Program Files\MongoDB\Server\4.4\bin.

Installing MongoDB on macOS

1. Download the MongoDB installer

You can download MongoDB directly from its official website or use Homebrew to install. If you're using Homebrew, simply run this command in your Terminal: brew tap mongodb/brew and then brew install mongodb-community@4.4.

1. Run MongoDB

After installation, you can run MongoDB by executing brew services start mongodb-community@4.4.

Installing MongoDB on Linux

1. Import the public key

MongoDB is signed with a public key to ensure that you're installing the authentic package. You can do this by running wget -qO - https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add -.

1. Create a list file for MongoDB

You can do this by running the command echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/4.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list.

1. Reload local package database

Run sudo apt-get update.

1. Install MongoDB packages

Finally, install MongoDB by running sudo apt-get install -y mongodb-org.

3. Code Examples

No code examples are included in this tutorial as it primarily deals with the installation of software through the command line or GUI.

4. Summary

In this tutorial, we've covered how to install MongoDB on Windows, macOS, and Linux. The key steps are to download the correct installer for your operating system, run the installer, and in some cases, set the MongoDB Environment Variable.

For additional resources on how to use MongoDB, you can visit the official MongoDB Documentation at https://docs.mongodb.com.

5. Practice Exercises

While there are no coding exercises for this tutorial, you can verify your MongoDB installation by running the command mongo in your terminal or command prompt. If installed correctly, you should see a MongoDB shell prompt.

You can also try to create a new MongoDB database or collection to further verify the installation.
