Hi,
I installed ES-5.0.0 and Kibana-5.0.0. I started ES. It worked true.

After I installed another programs (X-PACK, PHP CLIENT etc.) and I restart ES but it is not working.

My ES logs:

I tried to connect from the http://localhost:9200/ but not connected.

4

Did you use the user and password standard for the x-pack to access your ES server with http://localhost:9200?

5

+1

All logs are correct.

6

yes I used.

username:elastic
passw:changeme

and after I changed the password on kibana and it did not work

7

When I start ES it worked true.
I tried connect:

http://localhost:9200/

It didn't connect. I don't understand.

8

Can we have the rest of your logs please?

9

ok. I cleaned my log file and I restart ES-5.0.0.

You need to fix that:

[2016-11-08T17:41:11,546][ERROR][o.e.b.Bootstrap          ] [NchqMHF] node validation exception
bootstrap checks failed
max number of threads [1024] for user [elasticsearch] likely too low, increase to at least [2048]

Look at the doc. It explains all that.

I installed ES-5.0.0 rpm package. So I have to use system configuration file. (https://www.elastic.co/guide/en/elasticsearch/reference/master/setting-system-settings.html#ulimit)

It says,

When using the RPM or Debian packages, system settings and environment variables can be specified in the system configuration file, which is located in:

RPM

/etc/sysconfig/elasticsearch

Debian

/etc/default/elasticsearch

However, for systems which uses systemd, system limits need to be specified via systemd.

elasticsearch file: (/etc/sysconfig/elasticsearch)

I did not see anything wrong here. What is the problem?

I changed my elasticsearch.yml file.
I had an old elasticsearch.yml file(ES-2.4.1).
I replace my ES-2.4.1 elasticsearch.yml file with ES-5.0.0 elasticsearch.yml.
It connected . (http://localhost:9200)
I think The problem is in the elastic search.yml file

Problem solved
Thanks anyway.
