5.6.1 Prerequisites

Use the instructions in this section to run OpenSearch as a service on a Linux host, and to start automatically upon rebooting. Ensure that you fulfill these requirements:

• The OpenSearch process should not be running.

  If OpenSearch is running, ensure that it is not being used, and then stop the process.

  See Starting and Stopping an OpenSearch Service.

• The script to install the service must be run by the root user.

• OpenSearch is installed on the Linux server where you run this procedure.

• The OpenSearch and JDK installation directories are located under the DPK base directory; that is:

  • The DPK base directory is referred to in this documentation as BASE_DIR, such as /home/opensearch.

  • The OpenSearch installation directory, OSK_HOME, is found in BASE_DIR/pt/opensearch-3.2.0.

  • The Java installation directory, JAVA_HOME, is found in BASE_DIR/pt/os_jdk21.0.yy, where yy is the JDK version.

• OpenSearch must be run by the user who owns OSK_HOME.

  This is due to the fact that the script does not input the user name.

• You have downloaded and extracted the required OSK DPK for Linux, in a directory referred to as OSK_INSTALL.
