How to Install Elasticsearch on Ubuntu Server Latest

Introduction

Elasticsearch is an open-source, distributed search and analytics engine. It is highly scalable and can be used to search, store, and analyze large amounts of data. In this tutorial, we will learn how to install Elasticsearch on Ubuntu Server Latest.

Prerequisites

To follow along with this tutorial, you will need:

• A server running Ubuntu Server Latest.
• A user account with sudo privileges.

Step 1: Update Your System

Before we begin, let's update our Ubuntu system to the latest version.

sudo apt update
sudo apt upgrade

Step 2: Install Java

Elasticsearch requires Java to run. We will install the OpenJDK 8 package.

sudo apt-get install openjdk-8-jre-headless

Step 3: Install Elasticsearch

Elasticsearch can be installed using the Debian package provided by Elasticsearch.

sudo apt-get install apt-transport-https
wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
echo "deb https://artifacts.elastic.co/packages/7.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-7.x.list
sudo apt-get update
sudo apt-get install elasticsearch

Step 4: Start and Enable Elasticsearch

Once the installation is complete, start Elasticsearch using the following command:

sudo systemctl start elasticsearch.service

To ensure that Elasticsearch starts on boot, run:

sudo systemctl enable elasticsearch.service

Check the status of Elasticsearch to make sure it is running.

sudo systemctl status elasticsearch.service

Step 5: Verify Elasticsearch Installation

To verify that Elasticsearch is installed and running correctly, use the curl command to check the Elasticsearch version.

curl -X GET http://localhost:9200

The output should be similar to the following:

{
  "name" : "Gandalf Marvel",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "W57zE6vVRXK-E5k6l5UW2Q",
  "version" : {
    "number" : "7.10.2",
    "build_flavor" : "default",
    "build_type" : "deb",
    "build_hash" : "747e1cc71def077253878a59143c1f785afa92b9",
    "build_date" : "2021-01-13T00:42:12.435326Z",
    "build_snapshot" : false,
    "lucene_version" : "8.7.0",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

The version number should match the Elasticsearch version you installed.

Conclusion

In this tutorial, we learned how to install Elasticsearch on Ubuntu Server Latest. With Elasticsearch installed, you can begin to create indexes and start searching and analyzing large amounts of data.
