How to Install OpenSearch on Fedora CoreOS

OpenSearch is a search and analytics engine that allows you to search and analyze large amounts of data in real-time. In this tutorial, you will learn how to install OpenSearch on Fedora CoreOS.

Prerequisites

Before you begin, you will need the following:

• A Fedora CoreOS instance with root access
• Basic knowledge of Linux commands

Step 1: Install Java

OpenSearch requires Java 11 or higher to run. You can install OpenJDK from the Fedora repository using the following command:

sudo dnf install java-11-openjdk-devel

Step 2: Download and Extract OpenSearch

Download the latest version of OpenSearch from the official website using the following command:

wget https://artifacts.opensearch.org/releases/bundle/opensearch/1.0.0/opensearch-1.0.0-linux-x64.tar.gz

Extract the downloaded file using the following command:

tar -xvf opensearch-1.0.0-linux-x64.tar.gz

This will extract the contents of the OpenSearch archive to a new directory named opensearch-1.0.0.

Step 3: Configure OpenSearch

OpenSearch uses a configuration file to define its settings. Navigate to the opensearch-1.0.0/config directory and edit the opensearch.yml file:

cd opensearch-1.0.0/config
sudo vi opensearch.yml

Set the network.host option to 0.0.0.0 to allow remote access:

network.host: 0.0.0.0

Save the changes and exit the editor.

Step 4: Start OpenSearch

You can start OpenSearch using the following command:

cd ../bin
sudo ./opensearch

This will start OpenSearch in the foreground. To start OpenSearch in the background, use the following command:

sudo nohup ./opensearch &

Conclusion

You have successfully installed OpenSearch on Fedora CoreOS. You can now start using OpenSearch to search and analyze your data.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
