MongoDB is a popular NoSQL database that provides high performance, high availability, and easy scalability. In this guide, we will walk you through how to install and use MongoDB on Ubuntu 20.04 LTS. Whether you're hosting your database on a Windows VPS UK or another cloud platform, MongoDB is a robust choice for modern applications.

Prerequisites

Before starting, ensure you have the following:

• An Ubuntu 20.04 LTS server, which can be hosted on a UK Windows VPS, Windows Virtual Private Servers, or another Windows VPS Hosting UK solution.
• Root or sudo privileges on your server.

Step 1: Import the MongoDB Repository

MongoDB is not available in the default Ubuntu repositories, so you need to add the official MongoDB repository to your server. Start by importing the GPG key for the official MongoDB repository:

sudo apt update
wget -qO - https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add -

Next, add the MongoDB repository:

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

Step 2: Install MongoDB

Once the repository is added, update the package list and install MongoDB:

sudo apt update
sudo apt install -y mongodb-org

Step 3: Start MongoDB

After installation, start the MongoDB service and enable it to start at boot:

sudo systemctl start mongod
sudo systemctl enable mongod

Step 4: Verify MongoDB Installation

You can verify that MongoDB is running by checking its status:

sudo systemctl status mongod

You should see output indicating that MongoDB is active and running.

Step 5: Access the MongoDB Shell

To start using MongoDB, you can access the MongoDB shell by running:

mongo

This will bring you to the MongoDB shell, where you can run database commands.

Step 6: Basic MongoDB Commands

Here are a few basic MongoDB commands to get you started:

• Create a new database: In MongoDB, databases are created automatically when you insert data. To switch to a new database, use the following command:

use mydatabase

• Create a collection and insert data: Collections are created automatically when you insert data. To create a new collection and insert a document, use:

db.mycollection.insert({name: "John", age: 30})

• Find data in a collection: To find data stored in a collection, use the find() method:

db.mycollection.find()

Step 7: Secure MongoDB (Optional)

By default, MongoDB allows connections only from localhost. To allow remote access, you can modify the MongoDB configuration file:

sudo nano /etc/mongod.conf

Find the line that starts with bindIp and modify it to include your server’s IP address:

bindIp: 127.0.0.1, your-server-ip

After making this change, restart MongoDB:

sudo systemctl restart mongod

Conclusion

By following these steps, you have successfully installed and started using MongoDB on Ubuntu 20.04 LTS. Whether you're hosting your MongoDB database on a Windows VPS UK, Windows VPS Italy, or another Windows Virtual Private Server Hosting solution, MongoDB provides a scalable and flexible NoSQL database for your applications.
