Installing Elasticsearch Head Plugin: A Step-by-Step Guide

Introduction

Elasticsearch Head is a powerful client tool for Elasticsearch that allows you to easily manage and monitor your Elasticsearch clusters. In this article, we will walk you through the installation process of the Elasticsearch Head plugin, including the necessary configuration and setup.

Prerequisites

Before we begin, please note that Elasticsearch 5.x and above does not support the installation of the Elasticsearch Head plugin as a traditional plugin. However, we can use a Docker container to install an older version of the plugin, which is sufficient for our purposes.

Installation

To install the Elasticsearch Head plugin using Docker, follow these steps:

  1. Clone the project: Clone the repository using the following command:
git clone https://github.com/bboysoulcn/awesome-dockercompose.git
  1. Navigate to the Elasticsearch Head directory: Change into the Elasticsearch Head directory using the following command:
cd awesome-dockercompose/elasticsearch-head
  1. Run the Docker container: Use the following command to start the Docker container:
docker-compose up -d

This will start the Elasticsearch Head plugin in detached mode.

Configuration

By default, the Elasticsearch Head plugin is not configured to connect to your Elasticsearch instance. To configure the plugin, you need to modify the Elasticsearch configuration file.

Edit the Elasticsearch configuration file: Open the Elasticsearch configuration file using the following command:

vim /etc/elasticsearch/elasticsearch.yml

Modify the network host: Change the network.host setting to 0.0.0.0 to allow external access to Elasticsearch:

network.host: 0.0.0.0

Enable CORS: Add the following configuration to enable CORS:

http.cors.enabled: true
http.cors.allow-origin: "*"

This will solve the cross-domain problem.

Start Elasticsearch: Once the configuration is complete, start Elasticsearch using the following command:

cd /usr/share/elasticsearch/bin
su elk
./elasticsearch -d

Access the Elasticsearch Head plugin: Visit http://ip:9100 to access the Elasticsearch Head plugin. You can connect to your Elasticsearch instance by writing the address http://ip:9200 in the plugin.

Conclusion

In this article, we have walked you through the installation process of the Elasticsearch Head plugin using Docker. We have also configured the plugin to connect to your Elasticsearch instance and enabled CORS to solve the cross-domain problem. With this setup, you can easily manage and monitor your Elasticsearch clusters using the Elasticsearch Head plugin.
