Hi everyone one. I am a junior sysadmin and I am very new to Elasticsearch.
My OS is CentOS 6.9 and I have installed elasticsearch-2.4.6 with Java 1.8.0_191
When I start the elasticsearch service I get the following error:
service elasticsearch start
Starting elasticsearch: log4j:ERROR setFile(null,true) call failed.
java.io.FileNotFoundException: /var/log/elasticsearch/elasticsearch.log (Permission denied)
log4j:ERROR Either File or DatePattern options are not set for appender [index_search_slow_log_file].
Exception in thread "main" java.lang.IllegalStateException: Unable to access 'path.data' (/var/lib/elasticsearch/elasticsearch)

Refer to the log for complete error details.
[FAILED]
From that I've gone to look at the following logs:
java.io.FileNotFoundException: /var/log/elasticsearch/elasticsearch.log (Permission denied)
java.io.FileNotFoundException: /var/log/elasticsearch/elasticsearch_deprecation.log (Permission denied)
java.io.FileNotFoundException: /var/log/elasticsearch/elasticsearch_index_indexing_slowlog.log (Permission denied)
java.io.FileNotFoundException: /var/log/elasticsearch/elasticsearch_index_search_slowlog.log (Permission denied)
But the logs don't exist. Also with it stating "Permission denied" I did check the permission on the /var/log/elasticsearch folder and it was drwxr-xr-x which I would have through would be correct as I am starting the services as root.
Not sure where to look next, can anyone point me in the right direction?
Many thanks
