You can not start elasticsearch a `root` user. Make sure you read the installation documentation: [https://www.elastic.co/guide/en/elasticsearch/reference/7.2/install-elasticsearch.html](https://www.elastic.co/guide/en/elasticsearch/reference/7.2/install-elasticsearch.html) depending on your OS and the way you want to install it. ---

I'd recommend reading this [Elastic Install and Run - Root or Not?](https://discuss.elastic.co/t/elastic-install-and-run-root-or-not/151323) ---
