How To Install OrientDB on Ubuntu 20.04 LTS

In this tutorial, we will show you how to install OrientDB on Ubuntu 20.04 LTS. For those of you who didn’t know, OrientDB is an open-source NoSQL database management system written in Java. One of its main features is that it is not only NoSQL-based but also very fast. It is the most versatile DBMS which supports Graph, Document, Reactive, Full-Text, Geospatial, and Key-Value models in one Multi-Model product.

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 the OrientDB open-source NoSQL database on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.

Prerequisites

• A server running one of the following operating systems: Ubuntu 20.04 (Focal Fossa).
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• SSH access to the server (or just open Terminal if you’re on a desktop).
• An active internet connection.
• 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.

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