How to Install OpenSearch on Alpine Linux Latest

OpenSearch is a distributed search and analytics engine that is built on the Apache Lucene search library. In this tutorial, we will show you how to install OpenSearch on Alpine Linux Latest.

Prerequisites

Before we proceed with the installation process, please make sure you have the following:

A server running Alpine Linux Latest.
A user account with sudo privileges.

Step 1: Update your packages

We begin by updating the package index of your Linux server. You can do this by running the commands:

sudo apk update

Step 2: Install Java 11

OpenSearch requires Java to run. Run the following command to install Java 11:

sudo apk add openjdk11

Next, verify that Java is correctly installed by running the following command:

java -version

You should see output similar to this:

openjdk version "11.0.10" 2021-01-19
OpenJDK Runtime Environment (build 11.0.10+9)
OpenJDK 64-Bit Server VM (build 11.0.10+9, mixed mode)

Step 3: Download and extract OpenSearch

The next step is to download and extract the OpenSearch package. You can do this by visiting the OpenSearch downloads page, copying the link to the latest version of OpenSearch, and running the following command:

wget https://artifacts.opensearch.org/releases/bundle/opensearch/1.0.0/opensearch-1.0.0-linux-x64.tar.gz

This will download the tarred and gzipped archive of the OpenSearch package. The next step involves extracting the archive. Execute the following command to extract OpenSearch:

tar -xzf opensearch-1.0.0-linux-x64.tar.gz

Step 4: Configure OpenSearch

Now that we have the OpenSearch package extracted, we need to configure it. To do so, navigate to the directory where the package has been extracted and execute the following command:

cd opensearch-1.0.0/
sudo nano config/opensearch.yml

This will open the configuration file in the Nano text editor. Edit the following properties in the configuration file:

cluster.name: opensearch-cluster
node.name: opensearch-node-1
path.data: /var/lib/opensearch/data
path.logs: /var/log/opensearch

Save and exit.

Step 5: Enable and start OpenSearch

Now, we need to enable OpenSearch as a service so that it can start up with the operating system. We can do this by running the following command:

sudo bin/opensearch-service enable

Once that is done, you can start OpenSearch:

sudo bin/opensearch-service start

Check that OpenSearch is up and running by using the following command:

curl -XGET https://localhost:9200/

Conclusion

By following the steps outlined above, you have successfully installed and configured OpenSearch on Alpine Linux Latest. You can now integrate this powerful search engine into your projects!
