I have installed jdk1.8.0_131,elasticsearch-5.4.2 along with logstash 5.4.2 ,kibana 5.4.2 and X-Pack 5.4.2 for a non-admin user on Centos 7.
I made also some configuration for elasticsearch.
When trying to start elasticsearch I get:
[INFO ][o.e.b.BootstrapChecks ] [aOYJKcV] bound or publishing to a non-loopback or non-link-local address, enforcing bootstrap checks
ERROR:  bootstrap checks failed
: max file descriptors  for elasticsearch process is too low, increase to at least 
I have tried to fix by following https://github.com/elastic/elasticsearch/issues/17430 but still have problem starting...
Could you please help with some advice?
