Elasticsearch 5.6.0 not starting (no logs in logfiles made)

Elastic Stack Elasticsearch

I am having trouble starting elasticsearch.

I upgraded it to 5.6.0 2 days ago.

Today, I stopped it, and installed searchguard for 5.6.0.

Now, when I started elasticsearch, it is not getting started.

No logs are being made in the / var/log/elasticsearch/elasticsearch.log

Does it start if you remove the plugin?

3

yes, it did start when I remove the plugin.

Then it sounds like a problem with that plugin, you may want to contact the author of it for support.
