default Compatibility Install OpenSearch 2

Operating system and JVM compatibility

  • We recommend installing OpenSearch on RHEL- or Debian-based Linux distributions that use 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 15.0.1+9 (non-LTS), while OpenSearch 1.3.0 includes Java 11.0.14.1+1 (LTS).

  • OpenSearch 1.0 to 1.2.4 is built and tested with Java 15, while OpenSearch 1.3.0 is built and tested with Java 8, 11 and 14.

    To use a different Java installation, set the OPENSEARCH_JAVA_HOME or JAVA_HOME environment variable to the Java install location. We recommend Java 11 (LTS), but OpenSearch also works with Java 8.
