How to Install Elasticsearch on NixOS Latest

This tutorial will guide you through the process of installing Elasticsearch on NixOS Latest. Elasticsearch is a powerful, open-source search and analytics engine that allows you to store, search, and analyze large amounts of data in real-time.

Prerequisites

Before starting, ensure that you have the following:

• A computer running NixOS Latest
• Admin privileges on that computer
• A web browser to download Elasticsearch

Installation

To install Elasticsearch, follow the steps below:

1. Open a terminal window on your NixOS computer.

2. Download the Elasticsearch package by visiting the Elasticsearch website and clicking on the "Download" button for the latest version.

3. Extract the downloaded file using the following command:

   tar -xvf elasticsearch-7.x.x-linux-x86_64.tar.gz
   

   Replace 7.x.x with the version number you downloaded.

4. Move the extracted Elasticsearch directory to the /opt/ directory using the following command:

   sudo mv elasticsearch-7.x.x /opt/elasticsearch
   

   Replace 7.x.x with the version number you downloaded.

5. Change the ownership and permissions of the Elasticsearch directory using the following command:

   sudo chown -R elasticsearch:elasticsearch /opt/elasticsearch
   sudo chmod -R 755 /opt/elasticsearch
   

6. Configure Elasticsearch by editing the /opt/elasticsearch/config/elasticsearch.yml file using a text editor:

   sudo nano /opt/elasticsearch/config/elasticsearch.yml
   

   Add the following lines to the end of the file:

   network.host: 0.0.0.0
   http.port: 9200
   

   This will allow Elasticsearch to bind to all network interfaces and listen on port 9200.

7. Start Elasticsearch using the following command:

   sudo /opt/elasticsearch/bin/elasticsearch
   

   Elasticsearch should now be running on your computer.

Verification

To verify that Elasticsearch is running, open a web browser on your computer and navigate to http://localhost:9200/. You should see a response that includes information about the Elasticsearch version and cluster name.

Congratulations, you have successfully installed Elasticsearch on NixOS Latest!

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!
