Install Apache Solr on Ubuntu 22.04

In this tutorial, we will show you how to install Apache Solr on Ubuntu 22.04 LTS. For those of you who didn’t know, Apache Solr is an open-source search platform written on Java. It is based on Apache Lucene and is written in Java. Apache Solr is very highly scalable, fault-tolerant, and optimized for a high volume of internet traffic. It has its own set of plugins that are used for search as well as for indexing.

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 Apache Solr on Ubuntu 22.04 (Jammy Jellyfish). You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.

Prerequisites

  • A server running one of the following operating systems: Ubuntu 22.04, 20.04, and any other Debian-based distribution like Linux Mint.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo useror 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.
