How To Install MongoDB on Ubuntu 22.04

In this guide, we will explain how to install MongoDB on Ubuntu 22.04, providing a scalable NoSQL database solution for your applications and data management.

MongoDB is an open-source NoSQL database that uses a flexible, document-oriented data model. Unlike traditional relational databases that use tables and rows, MongoDB stores data in JSON-like documents with varied structures. This makes it highly adaptable and suitable for applications requiring scalable, high-performance, and flexible data storage solutions.

Prerequisites

• Launch the Ubuntu 22.04 instance on Neevcloud

• Access the server using SSH

Update && Upgrade the system

First, ensure your package list is up to date to avoid any issues with outdated packages

sudo apt-get update -y
sudo apt-get upgrade -y

Installation MongoDB

Execute the given command to install the MongoDB package.

 sudo apt install software-properties-common gnupg apt-transport-https ca-certificates -y

Add necessary packages

To install the most recent MongoDB package, you need to add the MongoDB package repository to your sources list file on Ubuntu.

curl -fsSL https://pgp.mongodb.com/server-7.0.asc |  sudo gpg -o /usr/share/keyrings/mongodb-server-7.0.gpg --dearmor

After this next. add MongoDB APT repository to the /etc/apt/sources.list.d/ directory.

echo "deb [ arch=amd64,arm64 signed-by=/usr/share/keyrings/mongodb-server-7.0.gpg ] https://repo.mongodb.org/apt/ubuntu jammy/mongodb-org/7.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-7.0.list

Next, include the MongoDB source list file in the /etc/apt/sources.list.d/ directory, which consists of a lone line stating

echo "deb [ arch=amd64,arm64 signed-by=/usr/share/keyrings/mongodb-server-7.0.gpg ] https://repo.mongodb.org/apt/ubuntu jammy/mongodb-org/7.0 multiverse"

• Add all repositories first, then update the packages

sudo apt update 

Now, proceed to install the mongodb-org meta-package, which includes MongoDB.

sudo apt install mongodb-org -y

Verify the version of MongoDB Installed

sudo mongod --version

Start and Enable MongoDB

• After installation, the MongoDB service starts and enables

sudo systemctl start mongod

• Enable it to start when the system rebooted

sudo systemctl enable mongod

Manage MongoDB Service

To verify the database's status, make sure the server is actively listening on port 27017.

ss -antpl | grep 27017

To check the status

Verify that the database service is active and running. Run the following command

sudo systemctl status mongod

Create MongoDB databases and User

Make sure the MongoDB instance is up and set up for remote access, then learn how to create a database and a user in MongoDB.

To access the MongoDB, run the following command.

sudo mongosh

By default, installation results in the creation of three databases. This includes admin, config, and local.

To list the existing databases, run these commands.

show dbs

To make a database, execute the use command with the name of the database. For example, to create a database named test_db, run the command

use test_db

To verify the database you are using, execute the db command. In this scenario, the output will be test_db.

To create a User

MongoDB offers various shell techniques to control your database. The db.createUser function enables the creation of a new user within a database.

This is how you can create a user name test_user with read-and-write roles for the test_db database.

db.createUser(
  {
    user: "test_user",
    pwd: "test-password",
    roles: [ { role: "readWrite", db: "test_db" } ]
  }
)

You can list the users created using the db.getUsers() command.

db.getUsers();

Alternatively, run the command

show users
