Elasticsearch process is killed on Centos 7 - Newbie

[Dwijadas (Dwijadas Senapati)]

Continuing the discussion from Elasticsearch process is killed on Centos 7:

Since existing topic was closed I open a new one.

I cant even see any logs at /var/log/elasticsearch/

any idea ?

If there is no logs, it is likely failing before the process is launched to the point that it starts logging.

Check journalctl -u elasticsearch.service (scroll to the very end). It should have some details on why the process can’t start.

Initially i notice there are errors related to memory, I increased the RAM to 4GB for the Virtual Machine. then there were errors from java about the VM has 1 core.. once I increased the VM core 2 no error and elastic search seems to be running.
