# Operating system and JVM compatibility
- We recommend installing OpenSearch on RHEL- or Debian-based Linux distributions that use [systemd](https://en.wikipedia.org/wiki/Systemd), such as CentOS, Amazon Linux 2, and Ubuntu (LTS). OpenSearch should work on many Linux distributions, but we only test a handful.
- The OpenSearch tarball ships with a compatible version of Java in the `jdk` directory. To find its version, run `./jdk/bin/java -version`. For example, the OpenSearch 1.0.0 tarball ships with Java 15 (non-LTS).
{% comment %}`./jdk/bin/java -version` doesn't work on macOS with zsh at the moment, and I have no idea why. Maybe we need a macOS artifact. Regardless, the command works on Amazon Linux 2 with bash and presumably other distros. - aetter{% endcomment %}
To use a different Java installation, set the `OPENSEARCH_JAVA_HOME` environment variable to the Java install location. We recommend Java 11 (LTS), but OpenSearch also works with Java 8.
