How To Install Apache Solr on Ubuntu 20.04 LTS

Install Apache Solr on Ubuntu 20.04

In this tutorial, we will show you how to install and configuration of Apache Solr on Ubuntu 20.04 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. Just like Elasticsearch, it supports database queries through REST APIs. Solr aims at providing distributed indexing, replication, and load-balanced querying with automated failover and recovery.

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 Apache Solr on a Ubuntu 20.04 (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.
  • 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.
