How to Install Elasticsearch on Fedora 32/31/30

Elasticsearch is a modern search and analytics engine based on Apache Lucene. It is completely open source and built with Java. It stored data in form of documents and provides APIs for the full-text search. Elasticsearch is distributed under the Apache 2 license, which provides it flexibility.

This tutorial will help you to install and configure elasticsearch on Fedora Linux systems.

Prerequisites

Java is the primary requirement for running elasticsearch. We assume you already have Java installed on your Fedora system.

You can use following command to install OpenJDK java on your system. Open a terminal and execute:

sudo dnf install java-11-openjdk 

After installation, check the Java version:

java -version 

Step 1 – Install ElasticSearch on Fedora

1. First of all, Download and install the Public Signing Key for elasticsearch:

   sudo rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch 
   

2. Next create a repository file elasticsearch.repo in the directory /etc/yum.repos.d and add below content to file.

   [Elasticsearch-7]
   name=Elasticsearch repository for 7.x packages
   baseurl=https://artifacts.elastic.co/packages/7.x/yum
   gpgcheck=1
   gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
   enabled=1
   autorefresh=1
   type=rpm-md
   

   Save this file and close it.

3. Clean the dnf cache and install elasticsearch package on your fedora system:

   sudo dnf clean 
   sudo yum install elasticsearch 
   

Elasticsearch RPM package has been installed. Next you need to configure elasticsearch based on your environment.

Step 2 – Configure Elasticsearch

Edit the elasticsearch configuration file elasticsearch.yml and set the network.host to localhost. You can also change it to the system LAP IP address to make it accessible over the network.

vim /etc/elasticsearch/elasticsearch.yml 

  network.host: localhost

Then enable the elasticsearch service and start it.

sudo systemctl enable elasticsearch 
sudo systemctl start elasticsearch 

The ElasticSearch has been successfully installed and running on your Fedora system.

Step 3 – Test Elasticsearch

Elasticsearch listen on port 9200 for the REST APIs. Port 9300 is used by the elasticsearch for communication between nodes.

Let’s connect on port 5200 via REST API to view the elasticsearch version.

curl -X GET "localhost:9200/?pretty" 

You will see the results like below:

{
  "name" : "tecadmin",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "HY8HoLHnRCeb3QzXnTcmrQ",
  "version" : {
    "number" : "7.9.2",
    "build_flavor" : "default",
    "build_type" : "rpm",
    "build_hash" : "d34da0ea4a966c4e49417f2da2f244e3e97b4e6e",
    "build_date" : "2020-09-23T00:45:33.626720Z",
    "build_snapshot" : false,
    "lucene_version" : "8.6.2",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

As the the above connected node name is tecadmin running elasticsearch version 7.9.2.

Conclusion

In this tutorial, you have learned to install and configure elasticsearch on Fedora Linux system.
