Problems when starting elasticsearch

Hello there,
I'm working on a VM on RHEL 7.4 and I need to install ElasticSearch and Kibana. But here is my problem, elasticsearch is installed on my vm but when I try to start it i got this :

I check what happened by using systemctl status elasticsearch.service and here is the result :
I checked if I have Java and yes I have the OpenJDK 1.8 image

I know that there are other topics here who talked about it so I tried modify different files but with no success ! That why I'm asking for your help ! Please !

Hi @fgomez17,

You may find the reason Elasticsearch is not starting in the logs. By default they go to /var/log/elasticsearch. Can you check it and paste the relevant parts here?
