ElasticSearch won't start when path.logs and path.data is changed

Elastic Stack Elasticsearch
1

I have followed the guide here to install ELK in CentOS 7, and it worked.

The next day, I tried to change the path of the data and logs on another volume, but failed, so I changed it to local directory. ( /etc/elasticsearch/elasticsearch.yml)

Here's my config

# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
path.data: /opt/elasticsearch/data
path.logs: /opt/elasticsearch/logs

But, when I restart ElasticSearch this is what I get:

 elasticsearch.service - Elasticsearch

I did set the ownership to elasticsearch:

/opt/elasticsearch
[root@localhost elasticsearch]# ls -al
total 4
drwxr-xr-x. 4 elasticsearch elasticsearch   28 Jan 26 07:29 .
drwxr-xr-x. 7 root          root          4096 Jan 26 07:29 ..
drwxr-xr-x. 2 elasticsearch elasticsearch    6 Jan 26 07:29 data
drwxr-xr-x. 2 elasticsearch elasticsearch    6 Jan 26 07:29 logs

I even tried on a fresh CentOS 7, but the outcome is same. What am I missing here?

Note: I'm new to this ELK, and just started experimenting with it as alternative for Splunk.

I will appreciate for any help I can get.

Thanks!

Hi Reynold,

the output says:

From what I can infer from the source code, there is a problem when loading settings.

Are there more details in the log files in /opt/elasticsearch/logs?
