Well, is ES actually running? Can you connect to it from the machine Kibana runs on?

Okay, but that doesn't answer my questions. Is ES actually running? Can you connect to it from the machine Kibana runs on?

@sarbjeet your ES isn't working fine. Check the configuration file for same and then try connecting Kibana to it.

Make sure that you shutdown the ES before making any up-gradations. I hope so this might work fine 🙂

Never mind if it works when you run it in a terminal. Focus on getting it working as a service because that's how it's actually going to be running. So `service elasticsearch restart` is successful, yes? Does [http://localhost:9200/](http://localhost:9200/) work then? If not, what's in the Elasticsearch logs in /var/log/elasticsearch?

in my ES config file:-
network.host=localhost.

Please answer my questions. I will not ask again.
So `service elasticsearch restart` is successful, yes? Does [http://localhost:9200/](http://localhost:9200/) work then?

So is the Elasticsearch process running at all (check with `ps aux | grep elasticsearch`)? If not, check the end of /var/log/elasticsearch/elasticsearch.log for clues.

Okay, so Elasticsearch is not running. Then please answer my second question.
You are asking very basic questions about how to use and run a Linux system. I want to spend my volunteer time helping people with Elastic-related problems and if this thread continues like this I'm going to bail.
