Getting Started with MongoDB on Ubuntu

MongoDB is a popular NoSQL database that provides high performance, high availability, and easy scalability. This tutorial will guide you through the steps of installing and setting up MongoDB on an Ubuntu system.

Prerequisites

• A system running Ubuntu (preferably 20.04 or later).
• Root or sudo privileges to install packages.

1. Import the MongoDB Public Key

First, you need to import the MongoDB GPG public key to ensure package authenticity:

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

2. Create a List File for MongoDB

Next, create a list file for MongoDB. Use the following command to create a new source list:

echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/multiverse amd64 packages" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list

Replace focal with your Ubuntu version (e.g., bionic for 18.04).

3. Update Package Index

Update the local package index to include the MongoDB packages:

sudo apt update

4. Install MongoDB

Install the latest version of MongoDB:

sudo apt install mongodb-org -y

This command installs the MongoDB server and client along with the necessary dependencies.

5. Starting MongoDB

After installation, start the MongoDB service with the following command:

sudo systemctl start mongod

To enable MongoDB to start automatically on boot, run:

sudo systemctl enable mongod

6. Checking MongoDB Status

You can check if MongoDB is running by using:

sudo systemctl status mongod

You should see an output indicating that the MongoDB service is active (running).

7. Accessing the MongoDB Shell

To interact with your MongoDB database, open the MongoDB shell by running:

mongo

This will launch the MongoDB shell where you can execute database commands.

8. Creating and Managing Databases

Once in the MongoDB shell, you can create a new database using:

use my_new_database

To insert data, use:

db.my_collection.insert({ name: "example", type: "demo" })

9. Stopping MongoDB

To stop the MongoDB service, use:

sudo systemctl stop mongod

10. Conclusion

You have successfully installed and set up MongoDB on Ubuntu. This NoSQL database is powerful for handling various data types and can scale easily as your application grows. Explore more about MongoDB’s features to fully utilize its capabilities!
