title: Error When Installing Magento - Could not validate a connection to Elasticsearch
body: <p>I'm installing Magento 2 for the first time following this tutorial <a href="https://www.javatpoint.com/how-to-install-magento-2-using-composer" rel="nofollow noreferrer">https://www.javatpoint.com/how-to-install-magento-2-using-composer</a>. XAMPP is installed (with Apache and MySQL running), the database is setup on PHPMyAdmin, but when I try to run <strong>php bin/magento setup:install</strong> (step 23 in the tutorial) I get the error: <code>Could not validate a connection to Elasticsearch. No alive nodes found in your cluster</code></p>
  <p>How can I fix this?</p>
