How to install Elastic Search

This is my first blog as a part of ELK stack series. As the first blog in this series, I’ll showing how to install Elastic Search, configure it, Start the service and get a response from it.

Pre Requisites

Elasticsearch is built using Java, and includes a bundled version of OpenJDK within each distribution. So make sure java is already installed on the machine.

Installation

Easy, Search for Install Elastic Search and go with the first link you see. Here is what comes today from elastic, the company behind this service. Depending on your platform, download the .gz or .deb or .zip file.

Installation on Windows

Well, its simple and Hard.

Simple: Extract the zip file.

Hard: Wait forever for the extraction to complete or at least as on today. I strongly recommend you to do the extraction when you can afford few hours of downtime or away time from your machine.

Post Extraction Steps for Windows

Set the path

Copy the path where the file is extracted (Example path below) and map it to an new system or user variable.

Update config

1. Navigate to elasticsearch\elasticsearch-8.15.2\config

2. Open elasticsearch.yml file in your fav editor

3. Uncomment & change the details as below.

# The placeholders are already there in the yml file. 
# Change values accordingly.

cluster.name: my-test-application
node.name: windows-node-1
network.host: 127.0.0.1 
# 127.0.0.1 or you can use ipconfig and take the ip address
cluster.initial_master_nodes: ["windows-node-1"]
xpack.security.enabled: false
# this is to disable security. Do not use this for production setup
