On the same page I gave you, you have a chapter "configuration". I think you should at least read it. Also on the guide, there is a search bar. Very useful to search for some information.

Include -Djava.net.preferIPv4Stack=true to your JAVA\_OPTS environment variable before starting Elasticsearch. Also read up on the network page that David referred to: > **[Elasticsearch Platform — Find real-time answers at scale](https://www.elastic.co)** > > Power insights and outcomes with the Elasticsearch Platform and AI. See into your data and find answers that matter with enterprise solutions designed to help you build, observe, and protect. Try Elasticsearch free today. If you want a control wrapper around Elasticsearch, you might be better off installing via rpm/yum and not use the service wrapper.
