MongoDB is a popular document-oriented NoSQL database system known for its high performance, openness, scalability, and flexibility. For developers and database administrators, it's crucial to know how to properly install and configure MongoDB on various operating systems. In this article, we'll look at the process of installing and performing basic configurations of MongoDB on Linux, Windows, and macOS.

Installation on Linux

1. Adding MongoDB Repository

On most Linux distributions, you'll first need to add the official MongoDB repository. For Ubuntu, you can use the following commands:

wget -qO - https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add -
echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/4.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list

2. Installing MongoDB

After adding the repository, you can install MongoDB using the package manager:

sudo apt-get update
sudo apt-get install -y mongodb-org

Starting MongoDB

Once installed, you can start MongoDB and enable it to start automatically on system boot:

sudo systemctl start mongod
sudo systemctl enable mongod

Installation on Windows

1. Downloading Installation File

For Windows, simply visit the official MongoDB website and download the installation file for Windows. During installation, you can choose the installation type and the directory where you want MongoDB installed.

2. Installing MongoDB

Run the downloaded installation file and follow the instructions in the installation wizard. During the installation process, you can choose whether to install MongoDB as a service.

3. Configuration and Startup

After installation, you can configure the path to database files and logs. Then, you can start MongoDB by running mongod.exe with the appropriate parameters.

Installation on macOS

1. Installation using Homebrew

On macOS, the easiest way to install MongoDB is by using the Homebrew package manager:

brew tap mongodb/brew
brew install mongodb-community

2. Starting MongoDB

You can start MongoDB using the Homebrew service:

brew services start mongodb/brew/mongodb-community

Basic Configuration

After installing MongoDB on any operating system, it's essential to perform basic configurations to ensure security and optimal performance. This includes:

• Enabling Authentication: Modify the mongod.conf configuration file to enable authentication and create user accounts with appropriate permissions.

• Securing Network Access: Restrict database access to trusted IP addresses only and enable data encryption during transmission.

• Replication and Backup Configuration: Increase fault tolerance and data loss prevention by setting up data replication and regular backups.

For specific steps and configuration examples, we refer to the official MongoDB documentation, which provides detailed information and guides for various operating systems and configuration scenarios.
