Completly deinstall and remove Elasticsearch for complete restart and begin new

After experimenting with Elasticsearch I'm searching for a way to completely remove everything concerning Elasticsearch on my server. I made quite a few mistakes and want to start completely new with a new installation.

use the following command to know the pid of the node already running.

curl -XGET 'http://localhost:9200/_nodes/process'

It took me an hour to find out the way to kill the node and could finally do it after using this command in the terminal window.

**For Linux users:

kill -9 {pid}

** will terminate the elasticsearch from the RAM. And then you can delete as the other answers suggest.

Simply find the Java process that Elasticsearch is in and kill, or use curl -XPOST /*Your Ip*/:9200/_shutdown.

Then remove Elasticsearch from your system by simply deleting the ES files/folder.

Various different setups could require different deletion methods (linux use rm -rf ES dirs, windows the good ol' delete button will work, logstash may require additional steps) but as a general rule it's quite simply to remove.

If you wish to remove only the data you can delete the data dir, or wipe all your indexes and reindex.
