How to Install OpenSearch on NetBSD

OpenSearch is a search and analytics engine that can be used to rapidly develop applications with a powerful search functionality. In this tutorial, we will be explaining how to install OpenSearch on NetBSD.

Prerequisites

Before you begin, ensure you meet the following requirements:

• A NetBSD server instance
• The root access to the server
• The ability to use SSH

Step 1: Install Java

OpenSearch requires Java to be installed on your NetBSD server. Run the following command to check if Java is already installed:

java -version

If Java isn't installed, you will see the following message: "No Java runtime present, requesting install." In that case, run the below command to install Java:

pkgin update
pkgin install openjdk8

Step 2: Download OpenSearch

Next, download the latest version of OpenSearch from the official website. Use the wget command to download the file:

wget https://artifacts.opensearch.org/releases/bundle/opensearch/1.0.0/opensearch-1.0.0.tar.gz

Step 3: Extract OpenSearch

Once the download is complete, extract the downloaded file using the tar command:

tar -xzf opensearch-1.0.0.tar.gz

Step 4: Configure OpenSearch

OpenSearch comes pre-configured, but you might need to make a few adjustments to fit your needs. Use your preferred text editor to edit the opensearch-1.0.0/config/opensearch.yml file.

• Modify the cluster.name and node.name attributes to match your needs.
• Specify the IP addresses and ports for the nodes in the cluster in the discovery.seed_hosts attribute.
• Set the password for the admin role in the opendistro_security.authcz.admin_dn attribute.

Step 5: Start OpenSearch

Once you have successfully configured OpenSearch, start the engine by running the following command from the OpenSearch directory:

./opensearch

Step 6: Test OpenSearch

You can test OpenSearch by using your web browser to access the OpenSearch server URL.

http://YOUR-SERVER-IP:9200/

Conclusion

You have successfully installed OpenSearch on your NetBSD server. Use this powerful search engine to develop applications with a robust search functionality.
