ElasticSearch Wont Start after intial config

Elastic Stack Elasticsearch
1

After installing elastic i started it once just as a test, and the service started fine. I stopped it and continued to go through the 6.4 guide. Once i finished and tried to start the service again it now fails and gives very little output as to why. Any point in the right direction would be helpful. The service status is below:

[root@elk-001 tmp]# systemctl status elasticsearch.service

Is there anything in the Elasticsearch logs?

3

in the elasticsearch.log file only the below are not marked INFO:

[2018-09-18T15:10:48,603][WARN ][o.e.x.s.a.s.m.NativeRoleMappingStore] [B27nrvW] Failed to clear cache for realms [[]]

[2018-09-18T15:10:44,255][DEBUG][o.e.a.ActionModule ] Using REST wrapper from plugin org.elasticsearch.xpack.security.Security

Is there another log file i should be looking in for this?

4

What is the specification of the host where Elasticsearch is running?

5

running on a HP proliant running Centos7:

cores = 2
ram = 64g
disk = 500gb

actually i think this may be the root of the problem:
