I checked out [https://www.elastic.co/guide/en/elasticsearch/reference/current/\_installation.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/_installation.html) but I didn't see any OS requirements.

On that page it states, "The repositories do not work with older rpm based distributions that still use RPM v3, like CentOS5."

Bummer, I guess you will just need to use the tar.gz download then. It's OS agnostic.

"[Elasticsearch requires at least Java 7.](https://www.elastic.co/guide/en/elasticsearch/reference/current/_installation.html)"
Java 7 requires "[Red Hat Enterprise Linux 5.5+](https://www.java.com/en/download/help/sysreq.xml)" and above.
"[CentOS version numbers ... correspond to the major version and update set of Red Hat Enterprise Linux (RHEL) used to build a particular CentOS release.](https://en.wikipedia.org/wiki/CentOS)"
∴Elasticsearch requires CentOS version 5.5+, and will not function on CentOS 5.11.
That's what I was looking for. Thank you for inspiring me to track it down.
