How To Install Elasticsearch on Ubuntu 22.04

To install Elasticsearch on Ubuntu 22.04, you can follow these steps:

Step 1 : Import the Elasticsearch GPG key:

wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo gpg --dearmor -o /usr/share/keyrings/elastic.gpg

Step 2 : Add the Elasticsearch repository to the APT sources list:

echo "deb https://artifacts.elastic.co/packages/7.x/apt stable main" | sudo tee /etc/apt/sources.list.d/elastic-7.x.list

This command adds the Elasticsearch 7.x repository to your sources list.

Step 3 : Update the package index:

sudo apt update

Step 4 : Install Elasticsearch:

sudo apt install elasticsearch

This command installs Elasticsearch and its dependencies.
