OpenSearch is a search and analytics engine that allows you to search, analyze, and visualize data in real-time. In this tutorial, we will guide you through the installation process of OpenSearch on POP! OS.

Prerequisites

• POP! OS latest version
• A terminal with sudo privileges

Step 1: Installing Java

First, you must ensure that your system has Java installed. To check this, run the following command:

java -version

If Java is not installed, run the following command:

sudo apt-get install default-jre

Step 2: Downloading OpenSearch

Next, you must download the OpenSearch package from the official website. Run the following command to download the package:

wget https://artifacts.opensearch.org/releases/opensearch/opensearch-1.1.0-linux-x64.tar.gz

Step 3: Extracting OpenSearch

After downloading the package, extract it using the following command:

tar -xzvf opensearch-1.1.0-linux-x64.tar.gz

Step 4: Configuring Security

OpenSearch comes with built-in security features. You can configure these by creating a security configuration file. To create a security configuration file, navigate to the opensearch/config folder and create the file opensearch_security_configuration.yml.

cd opensearch-1.1.0-linux-x64
cd config
vi opensearch_security_configuration.yml

Then in the file, add the following lines and save the file:

opensearch_security:
  authc:
    anonymous_auth_enabled: true
    basic_internal_auth_domain:
      enabled: true
      order: 0
      http_authenticator:
        type: basic
        challenge: false
      authentication_backend:
        type: internal
    admin_dn:
      - 'CN=admin,OU=Ops,O=company,DC=org'

Step 5: Running OpenSearch

To run OpenSearch, go back to the root directory of the package and run the following command:

./bin/opensearch

Step 6: Accessing the OpenSearch Dashboard

Finally, to access the OpenSearch dashboard, open a web browser and navigate to http://localhost:9200. If you have configured security, you will need to enter the appropriate credentials.
