Password protect elasticsearch 7 cluster

I have installed elasticsearch 7 on Ubuntu. I have a basic licence. Now I want to password protect the cluster. I set true in elasticsearch.yml and run elasticsearch. And I get the following message:

Transport SSL must be enabled if security is enabled on a [basic] license. Please set [] to [true] or disable security by setting []


  1. Is it possible to password protect the cluster without enabling SSL?
  2. If I install SSL certificate on cluster nodes, would I also need to install SSL on my web server to communicate with elasticsearch?

It's heaps easier for people to assist you if you don't create so many threads around the same problem, and/or create a new topic and then just delete all the contents.

Let's carry on the conversation in this one - Setting = true
