Introduction
OpenSearch is a community-driven open-source search and analytics suite. This guide will walk you through the installation process for OpenSearch on a Windows VPS.
Prerequisites
- A Windows VPS with administrative access.
- Java JDK 11 or later installed (OpenSearch requires Java).
- Internet access to download OpenSearch.
Step 1: Install Java Development Kit (JDK)
If you don't have Java installed on your VPS, you need to install it. Follow these steps:
- Download the latest JDK from the Oracle JDK downloads page or from AdoptOpenJDK.
- Run the installer and follow the prompts to complete the installation.
- Set the JAVA_HOME environment variable:
setx JAVA_HOME "C:\Program Files\Java\jdk-"- Update the PATH environment variable (if necessary):
setx PATH "%PATH%;%JAVA_HOME%\bin"Step 2: Download OpenSearch
Go to the OpenSearch downloads page. Select the latest version of OpenSearch and download the ZIP package for Windows.
Step 3: Extract OpenSearch
Once the download is complete, locate the ZIP file and unzip it to a directory of your choice. For example, you could extract it to C:\OpenSearch.
Step 4: Configure OpenSearch
Navigate to the OpenSearch configuration directory:
cd C:\OpenSearch\configYou can modify the opensearch.yml configuration file as per your requirements. Use a text editor to open the file and make the necessary changes.
Step 5: Run OpenSearch
Navigate to the OpenSearch bin directory and start the service:
cd C:\OpenSearch\bin
opensearch.batThis will start OpenSearch as a foreground process in the command prompt. You may want to run it in a separate command prompt window.
Step 6: Verify OpenSearch Installation
To check if OpenSearch is running, open your web browser and navigate to:

- Download NSSM from its official website.
- Extract NSSM and run the following commands:
C:\path\to\nssm install OpenSearch
nssm set OpenSearch AppPath "C:\OpenSearch\bin\opensearch.bat"
nssm start OpenSearchConclusion
