RE : Ulimit property

Phani_Nadiminti · May 19, 2015, 1:11pm

Hi All,

Can we set Ulimit -l unlimited in RHEL servers as my servers running on production.es suggesting to give unlimited ulimit but my question is is it safe to enable Ulimit -l unlimited for root user on production servers?

Thanks

For root? Surely you're not running Elasticsearch as root?

Phani_Nadiminti · May 19, 2015, 1:40pm

Yes Magnus for root only .I am running elasticsearch as root.

Please don't run Elasticsearch as root. I can't imagine that there's any good reason for doing so.

Hi magnus ,

Thank you for suggesting so if i run elasticsearch under elastisearch user so we can set ulimit unlimited for elasticsearch user instead of defining in root am I correct?

Thanks

Yes, you can raise the ulimit for the Elasticsearch user too.
