How to Install OpenSearch on OpenBSD

In this tutorial, we will be discussing the installation process for OpenSearch on OpenBSD, a popular open-source search engine. OpenSearch offers advanced search features that allow users to search for content from multiple sources with a single query.

Prerequisites

Before we begin, make sure that you have the following prerequisites in place:

1. An OpenBSD system (version 6.9 or above) running as a server or desktop.
2. A user account with root or sudo access.

Step 1: Install Dependencies

First, we need to install some dependencies for OpenSearch to run on the OpenBSD operating system. Open a terminal window and run the following command to install the necessary packages:

sudo pkg_add openjdk-11.0.10p1 firefox

This command installs OpenJDK 11 and Firefox on your system.

Step 2: Download and Install OpenSearch

Now that we have installed the necessary dependencies, we can proceed with downloading and installing OpenSearch.

1. Open a terminal window and navigate to the directory where you want to download OpenSearch.

2. Download the latest version of OpenSearch by running the following command:

   sudo fetch -o opensearch-1.0.0.tar.gz https://artifacts.opensearch.org/releases/bundle/opensearch/1.0.0/opensearch-1.0.0-linux-x64.tar.gz
   

   This command will download the OpenSearch package to your current directory.

3. Extract the package by running the following command:

   sudo tar -xzvf opensearch-1.0.0-linux-x64.tar.gz
   

   This command will extract the OpenSearch package to a new directory called "opensearch-1.0.0".

4. Move the OpenSearch package to the "/usr/local/share" directory by running the following command:

   sudo mv opensearch-1.0.0 /usr/local/share/opensearch
   

   This will move the OpenSearch package to the appropriate directory.

5. Finally, create a symbolic link for the OpenSearch binary by running the following command:

   sudo ln -s /usr/local/share/opensearch/bin/opensearch /usr/local/bin/opensearch
   

   This will create a symbolic link for the OpenSearch binary, which will allow us to run OpenSearch from any directory in the terminal.

Step 3: Configure OpenSearch

Now that we have installed OpenSearch, we need to configure it to meet our requirements.

1. Navigate to the OpenSearch configuration directory by running the following command:

   cd /usr/local/share/opensearch/config/
   

2. Open the "opensearch.yml" file in your preferred text editor.

   sudo nano opensearch.yml
   

3. Find the line that starts with "cluster.name" and change the name to a name of your choice.

4. Save and close the file.

Step 4: Start and Stop OpenSearch

To start OpenSearch, run the following command:

sudo /usr/local/share/opensearch/bin/opensearch

This will start OpenSearch in the terminal window.

To stop OpenSearch, press "CTRL+C" in the terminal window where OpenSearch is running.

Conclusion

Congratulations! You have successfully installed OpenSearch on your OpenBSD system. You can now use OpenSearch to search for content from multiple sources with ease.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
