To start working with MongoDB, the first step is to have a MongoDB database set up. You have two main options: utilize a hosted service like MongoDB Atlas or install MongoDB locally on your computer. For those preferring to work offline, this guide will walk you through the installation process of MongoDB locally on your machine. Later in this guide, we will also cover how to set up a hosted database using MongoDB Atlas for more complex applications.

Step 1: Downloading MongoDB

1. Visit the MongoDB Download Page
   Go to the MongoDB Download Center. You will see several options for different editions of MongoDB.
2. Select Community Server Edition
   Choose the free Community Server Edition, designed for local development needs. Make sure to download the latest version available to ensure you have the most recent features and security patches.
3. Choose Your OS
   Select the version that corresponds to your operating system. The options typically include Windows, macOS, and Linux. For this guide, we will use Windows as the platform.
4. Download the Installer
   Hit the download button to start downloading the installer. This should only take a few moments depending on your internet speed.

Step 2: Installing MongoDB

Once the download is complete, follow these steps to install MongoDB:

1. Run the Installer
   Double-click the downloaded installer file to start the installation wizard.
2. Accept the License Terms
   Follow the prompts to accept the license terms and conditions; clicking “Next” will take you through the installation process.
3. Select Complete Installation
   Choose the “Complete” setup option when prompted. This ensures all components are installed, including essential tools.
4. Install MongoDB as a Service
   Ensure the option to “Install as a service” is checked. This feature allows MongoDB to run in the background on your computer and provides easier access.
5. Include MongoDB Compass
   Check the box to install MongoDB Compass, a GUI that will help you interact with your database visually. You’ll find this tool useful throughout the development process.
6. Finish the Installation
   Click on “Install” and wait while the installation completes. Once finished, MongoDB Compass may open automatically. If it does, minimize it for now as we will cover it later.

Step 3: Installing MongoDB Shell

To interact with MongoDB from command-line environments, you’ll need the MongoDB Shell tool:

1. Navigate to MongoDB Tools
   After the main installation is complete, go back to the MongoDB Download Center and select the tools option at the top.
2. Download the MongoDB Shell
   Find the MongoDB Shell in the available tools, and select the version that matches the server version you installed. Download and install this as well by following the standard installation prompts.

Step 4: Verifying Your Installation

To confirm your installation was successful, you can use the command prompt:

1. Open Terminal
   You can use the Command Prompt on Windows.
2. Run the Command
   Type mongosh and press Enter. If you see the MongoDB shell prompt and the version number displayed, you have installed MongoDB correctly! If not, there may have been an issue during the installation.

Step 5: Getting Started with MongoDB

Now that MongoDB is installed, you are equipped to interact with your database using both the MongoDB shell and Compass. While the shell is great for learning the basics in a language-agnostic environment, Compass provides a user-friendly interface for visualizing your data and operations.

In the upcoming sections of this guide, we will delve deeper into MongoDB’s data storage mechanics, focusing on collections and documents. Understanding these concepts is crucial as you progress with your projects.

Conclusion

Installing MongoDB locally opens up a world of possibilities for development. With both MongoDB Compass and the Shell at your disposal, you’re set to dive into database management and utilization effectively. Remember, if you prefer to work with a cloud-based solution, stay tuned as we’ll also explore how to set up a hosted MongoDB database with Atlas soon.
