Elastic Stack Elasticsearch

Hi all,

I wanted to know where does elasticsearch writes the log when run as service.
I tried starting the elasticsearch as service and it fails. Theres no data in /var/log/elasticsearch/elasticsearch.log

[root@sample test]# service elasticsearch status
ā— elasticsearch.service - Elasticsearch
   Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; enabled; vendo                                    r preset: disabled)

Please don't post images of text as they are hardly readable and not searchable.

Instead paste the text and format it with </> icon. Check the preview window.

If you upgraded the kernel recently, that might be the cause.

Sounds like your elasticsearch.yml config file has a bad format.

I've checked my elasticsearch yml file and verify it with http://www.yamllint.com/
and its all fine

I think the problem is within here

#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
 path.data: /var/lib/elasticsearch
#
# Path to log files:
#
 path.logs: /var/log/elasticsearch
#
# ----------------------------------- Memory -----------------------------------

I just remove the space before path.data & path.logs and its now working.

Btw, thank you dadoonet :slight_smile:

Glad you solve it. Indeed yaml format is a bit strict. :slight_smile:
