Setting up MongoDB environment

MongoDB is an open-source NoSQL database that provides high performance, high availability, and easy scalability. It works on the concept of collections and documents, making it a popular choice for many developers. Before we can dive into the specifics of MongoDB, we first need to set up the MongoDB environment on our systems. This tutorial guides you through the process of setting up the MongoDB environment on your system.

wget -qO - https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add -
  1. Create a list file for MongoDB.
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.
sudo apt-get update
  1. Install the MongoDB packages.
sudo apt-get install -y mongodb-org

Running MongoDB​

For Windows​

After the installation, you can start MongoDB by following these steps:

  1. Open the Command Interpreter (cmd.exe).
  2. Run the following command:
"C:\Program Files\MongoDB\Server\4.4\bin\mongod.exe"

For Linux​

For Linux systems, use the following commands to start, stop, and restart MongoDB:
