Hey everyone !

I'm currently following these two tutorial to enable elasticsearch security which is now free, but in these two tutorials, it's specified only for two node-cluster and i only have one,

my default elastic-search directory is located at `/usr/share/elasticsearch/`  
and the configuration file like the `elasticsearch.yml` is located at `/etc/elasticsearch`

I tried to adapt the tutorial as i could, but when i had to execute `bin/elasticsearch` and `bin/elasticsearch-setup-password auto`, i got errors of refused connection.

My question is, how to adapt this tutorial for a one node cluster, thank you in advance !

these are the links to the tutorials

"refused connection" indicates your es instance is probably not running, can you check the elasticsearch.log ?
