Introduction

Elasticsearch is a highly scalable open-source search and analytics engine that enables users to store, search, and analyze large amounts of data quickly and in near real-time. It's commonly used in a variety of applications, including web search, log analysis, and data exploration.

This article will explain how to install Elasticsearch on Fedora 34 and Fedora 35.

Prerequisites

• A root or non-root user with sudo privileges.

Install Java

1. Before we start the installation, updating the system to ensure that all packages are up-to-date is a good idea.

   # sudo dnf -y update

2. Elasticsearch requires Java to run, so the next step is to install the latest version of Java. Run the following command to install the OpenJDK 11 package.

   # sudo dnf -y install java-11-openjdk-devel

3. Verify the installed java version.

   # java -version

   

Install Elasticsearch

1. We will be installing Elasticsearch with the rpm after importing the GPG key.
   

   # sudo rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
   # sudo dnf -y install https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.16.3-x86_64.rpm

2. To start the Elasticsearch service and enable it to start automatically at boot time, run the following commands.

   # sudo systemctl start elasticsearch.service
   # sudo systemctl enable elasticsearch.service

3. To verify that Elasticsearch is running correctly, run the following command.
   

   curl -X GET "localhost:9200/"

   If Elasticsearch is running correctly, you should see an output similar to the following.
