How To Install MongoDB on Ubuntu 20.04 LTS

In this tutorial, we will show you how to install MongoDB on your Ubuntu 20.04 LTS. For those of you who didn’t know, MongoDB is one of the most popular implementations of the NoSQL database system. It’s a document-oriented database program with a JSON-like scheme, in which all your data is stored as a document with BSON format on the database collection.

MongoDB was a pioneer in the NoSQL world. It’s a distributed document-oriented database with high availability replication and sharding, a built-in caching system for speed, scalable for large deployment, and flexible for your applications.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of MongoDB on a Ubuntu 20.04 LTS (Focal Fossa) server.

Prerequisites

• A server running one of the following operating systems: Ubuntu 20.04, 18.04, 16.04, and any other Debian-based distribution like Linux Mint.
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install MongoDB on Ubuntu 20.04 LTS Focal Fossa

Step 1. First, make sure that all your system packages are up-to-date by running the following apt commands in the terminal.

sudo apt update
sudo apt upgrade
sudo apt gnupg

Step 2. Install MongoDB on Ubuntu 20.04.

By default, the latest version of MongoDB is not available in the Ubuntu 20.04 default repository. So you will need to add the official MongoDB repository to your system:

wget -qO - https://www.mongodb.org/static/pgp/server-4.2.asc | apt-key add -

Next, add the MongoDB repository with the following command:

echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/4.2 multiverse" | tee /etc/apt/sources.list.d/mongodb-org-4.2.list

After that, update your system and refresh existing repositories by running the commands below:

sudo apt update
sudo apt install mongodb-org

Once the installation has been completed, start the MongoDB service and enable it to start at reboot with the following command:

sudo systemctl start mongod
sudo systemctl enable mongod
sudo systemctl status mongod

Step 3. Configure MongoDB.

MongoDB default configuration file is located at /etc/mongod.conf. By default, each user will have access to all databases and perform any action.

nano /etc/mongod.conf

Add the following lines:

security:
  authorization: enabled

Save and close the file then restart the MongoDB service to apply the changes:

systemctl restart mongod
