Do you have java installed?
Also check /var/log/elasticsearch/, there should be something.

Hi Mark

I can't see any other file other than gc.log in /var/log/elasticsearch folder.

I cant see the elasticsearch.log generated in this server. Is there any other place where i need to check the log.

Any suggestions.

Thx
Muthu

Try looking through the following log and grepping for elasticsearch:

cat /var/log/audit/audit.log | grep elasticsearch

You might be able to find some more context as to why the service failed in this log.

This could possibly be related to SELinux and setting the host to 0.0.0.0, but I'm not 100% certain of that.

Hi Popa

I managed to solve this by downloading and installing zip file version of elastic search..

So Now , i am able to bring my elastic search by running the elastic search in Backfround.

Thanks..
Muthu
