Elasticsearch 5.2 service don't start

Elastic Stack Elasticsearch
1

Hello,
I need some help, and please excuse my english it's not my monther tongue.

I installed Elasticsearch 5.2 on Redhat 7 and after installation the service started.
I then turned it off to modify the configuration files /etc/elasticsearch/elasticsearch.yml and /etc/sysconfig/elasticsearch

Then I restarted it and I get this error:
[root@machine]# systemctl status elasticsearch.service

I read several topics concerning not start but none solved my problem.

Thank you for reading and help ^_^.

Check the actual ES log rather than this one, usually under /var/log/elasticsearch.

But it's a 16:32 and the starting failed was at 17:23:48 (Even if I tried several times to start it).
I will remove the plugin that looks badly installed and start again

That's why.

Adding that you can't install site plugins in elasticsearch: https://www.elastic.co/blog/running-site-plugins-with-elasticsearch-5-0

Thank you all for your support. I fixed it.

After removing the plugin, it still does not start.
Being user root, the elasticsearch service starts with the elasticsearch user in default and the /etc/elasticsearch folder did not have sufficient rights. So I did a chmod 777 on /etc/elasticserach and this solved the problem.

I'm not sure that's such a great idea: you have given all users all rights on your ES settings. As far as I know chmod 777 is almost never a solution.

I doubt there is write-access needed? You could either chown the stuff that needs to be written, but better would be to just give some read access to users, or maybe something like 755 ?

Ok, i will follow your advise in the futtur. Thank
