Hello,

First time trying to install and configure ElkStack on CentOS7 and ran into some issues. Was able to install the Elasticsearch package, however, I have not been able to start ElasticSearch after using `systemctl start elasticsearch`.

I receive the following error:  
Failed to start elasticsearch-.service: Unit not found.

Config yml is below. Are there any other logs I can use to troubleshoot?
