Sounds a Elasticsearch instance is already running. Do you set it to start automatically at boot time? I guess.

3

How can I stop the automatic start?

4

You can check Elasticsearch is running by several methods:

  1. test 9200 port (default Es port) is listening.
  2. run ps -ef | grep java to check.

If it is running, you don't have to start a another instance.

But I will check the port whether it works or not. It will not work. So I uninstall and then reinstall it and start the Elasticsearch .

I working in mac. So I give ps all command to see whether Elastic search is running in background or not. Sometimes there is no background process and Elasticsearch is also not starting.
