For macOS:

1. Run the Installer:

   • Locate the downloaded .dmg file and double-click to mount it.

2. Drag and Drop:

   • Drag the MongoDB icon to the Applications folder.

3. Create Data Directory:

   • Open the terminal and create a data directory for MongoDB:

     mkdir -p /data/db

4. Set Permissions:

   • Set permissions for the data directory:

     sudo chown -R `id -u` /data/db

5. Start MongoDB:

   • In the terminal, start MongoDB with the following command:

     mongod

For Linux:

1. Import the Public Key:

   wget -qO - https://www.mongodb.org/static/pgp/server-<version>.asc | sudo apt-key add -

2. Create the /etc/apt/sources.list.d/mongodb-org-<version>.list File:

   echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/<version>/multiverse amd64 Packages" | sudo tee /etc/apt/sources.list.d/mongodb-org-<version>.list

3. Update the Package Database:

   sudo apt-get update

4. Install MongoDB:

   sudo apt-get install -y mongodb-org

5. Start MongoDB:

   sudo systemctl start mongod

6. Enable MongoDB on Boot:

   sudo systemctl enable mongod

Step 3: Verify Installation

1. Open a New Terminal/Command Prompt:

   • Type the following command to start the MongoDB shell:

     mongo

2. Check MongoDB Version:

   • You should see the MongoDB shell starting with version information. If you see this, MongoDB is successfully installed!

Step 4: Basic MongoDB Commands

Now that MongoDB is installed, you can start using it with some basic commands:

• Show Databases:

  show dbs

• Create a Database:

  use myDatabase

• Insert Data:

  db.myCollection.insert({ name: "Pankaj", age: 25 })

• Find Data:

  db.myCollection.find()

Conclusion

Congratulations! You have successfully installed MongoDB on your system and are ready to start building applications. In future tutorials, we will explore MongoDB features, including CRUD operations and advanced querying.
