How to Install MongoDB on Ubuntu 16.04 to 22.04

8.6K

This tutorial will show you how to install MongoDB on Ubuntu 16.04 to 22.04 LTS.

The modern web is littered with apps that rely on MongoDB, a document database. The fact that it does not use the more common table-based relational database structure is what gives rise to its classification as a NoSQL database.

Since it employs JSON-like documents with dynamic schemas, adding data to a MongoDB database does not necessitate creating a schema in advance, as is the case with relational databases. Anytime you need to make a change to the schema, you may do it without having to create a whole new database.

Prerequisites

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

Install Libssl1 to avoid the error E: Unable to correct problems, you have held broken packages. Add its repository to your system using the command below.

echo "deb http://security.ubuntu.com/ubuntu impish-security main" | sudo tee /etc/apt/sources.list.d/impish-security.list

Update your system to apply changes.

sudo apt update

Then install Libssl1 using the following command.

sudo apt install libssl1.1

To Install MongoDB on Ubuntu 22.04, start by adding MongoDB APT repo signing key using the following command.

echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/5.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-5.0.list
