How to Configure Elasticsearch To Run On Localhost

Reading Time: 4 minutes

Hello Readers !!! Hope you all are doing well . Again I am here with a new post and In this post we’ll see How we can configure Elasticsearch To Run On Localhost . Firstly , we’ll see what is elastic search and how we can install it and after that we;ll configure elasticsearch on our local .

So, let’s get started !!!


What is ElasticSearch

Elasticsearch is a distributed, open-source, cost-free search and analytics platform for text, numbers, geographic, structured, and unstructured data. Built on Apache Lucene, Elasticsearch was first made available in 2010 by Elasticsearch N.V. (now known as Elastic).

It is called as the centrepiece of the Elastic Stack, a collection of free and open technologies for data intake, enrichment, storage, analysis, and visualisation, is renowned for its straightforward REST APIs, distributed nature, speed, and scalability.

The Elastic Stack, often known as the ELK Stack (after Elasticsearch, Logstash, and Kibana), now supports a wide range of lightweight shipping agents called Beats for transmitting data to Elasticsearch.


Elasticsearch is a platform for distributed search and analysis of data in real time .


An Ubuntu 22.04 server with 2GB RAM and 2 CPUs set up


if java is not install , you can install it from here Click OR run below command as :

sudo apt install openjdk-8-jdk

java version 

Here , are the installation steps that we have to install ElasticSearch . These are as follows :

STEP 1  install an APT transport package

To allow access to your repositories via HTTPS, you need to install an APT transport package by running command :

sudo apt install apt-transport-https

STEP 2 Add ElasticSearch Repository

First we need to update the GPG Key for the elastic search repository . Use the below command to do so :

wget -qO - | sudo apt-key 

add -

Next, use the below command to add the repository to your system .

echo "deb stable main" | sudo 

tee -a /etc/apt/sources.list.d/elastic-7.x.list

STEP 3 Install ElasticSearch

Now , let’s install elasticsearch , update the packages by running the command :

sudo apt update 

run the installation command as :

sudo apt install elasticsearch 

STEP 4 Start ElasticSearch Service

Once installed , you need to start the elasticsearch service . First reload the daemon and after that enable the elasticsearch service as :

sudo systemctl daemon-reload

sudo systemctl enable elasticsearch.service

and finally run :

sudo systemctl start elasticsearch 

sudo systemctl status elasticsearch 


Now , the most important thing that we have to configure elasticsearch . To make changes to the default Elasticsearch configuration, edit the elasticsearch.yml file. The file is located in the directory:

cd /etc/elasticsearch

and the configuration for logging is located in the:

cd /var/log/elasticsearch/logging.yml file
Allow Remote Access

The default configuration does not allow your machine to be accessed by other hosts. To allow remote access, use a text editor of your choice and open the elasticsearch.yml file as :

sudo su 

cd /etc/elasticsearch/

nano elasticsearch.yml

Scroll down to the Network section. Find the line that says

Uncomment the line (remove the pound (#) sign), set the IP address to , and add these lines:

check for the lines says #discovery.seed_hosts: [“Host1” , “Host2”]

Uncomment the line (remove the pound (#) sign) , and remove host1 , host2 from the bracket .

also uncomment #http.port: 9200

Now make changes to the file located at :

cd /etc/elasticsearch/jvm.options

here , In this file you have to look for the line which says : #-Xms4g , #-xmx4g

Uncomment the line (remove the pound (#) sign) like this :

So , we are set , now restart the elasticsearch service and check status by :

sudo systemctl restart elasticsearch

sudo systemctl status elasticsearch
Test Elasticsearch

Now test the elasticsearch service by running the command on terminal as :

curl localhost:9200

OR you can hit on the browser as :


All set !!! we are done . In this way we can install and configure ElasticSearch .


So, In this blog we have seen How we can Configure Elasticsearch To Run On Localhost and also we have seen what is elasticsearch and how we can install it . I hope this post is helpful for you all . Keep learning and keep shining . If you have any query , you can ask me .

Thank You !!!

Keep Learning !!!
