Elasticsearch process is killed on Centos 7

Elastic Stack Elasticsearch

Elasticsearch service can't start, I think some other process is killing it. Can you help me?

[root@vagrantbox ~]# systemctl status elasticsearch

I'm having the same problem. I just had the same problem with CentOS 6 aswell.

Look at /var/log/elasticsearch/ for some proper logging.

@warkolm thank you for your response.

Elasticserach log (/var/log/elasticsearch/elasticsearch.log) has the following content:
