Unable to run ES5.02 on ubuntu 16.04

[Karma]

I'm trying ES on Digital Ocean server, but having a problem when starting up ES.

Ubuntu 16.04.1 image (4gb)
Java openjdk-8-jre-headless
ES ver 5.0.2 (tar.gz)

Below is error message:

same for me ES5.02 on RHEL6.8.
Could ES get started after setting again:
xpack.security.http.ssl.enabled: false
but message still occurs.

I use debian install and it works.

Hey,

can you try to use the JDK instead of the JRE and check if you get the same message?

I think that you're starting Elasticsearch as a user pointing to a config file that that user does not have permission to access (/home/elasticsearch/config/elasticsearch.yml). This is the cause of

Exception in thread "main" SettingsException[Failed to load settings from /home
/elasticsearch/config/elasticsearch.yml]; nested: AccessDeniedException[/home/e
lasticsearch/config/elasticsearch.yml];

Similarly, you either do not have permissions to view the jvm.options file that ships with Elasticsearch, or you edited it. In that file is the system property -Dlog4j2.disable.jmx=true. This prevents the first exception:

2016-12-01 11:25:55,258 main ERROR Could not register mbeans java.security.Acce
ssControlException: access denied ("javax.management.MBeanTrustPermission" "reg
ister")

from occurring.

In both cases you need to ensure that you're starting Elasticsearch as a user that has permission to view the jvm.options and elasticsearch.yml configuration files.

Exactly as you said, it was a file permission issue. Thanks.
