Elasticsearch 8.x Cookbook - Fifth Edition

By: Alberto Paro

Overview of this book

Elasticsearch is a Lucene-based distributed search engine at the heart of the Elastic Stack that allows you to index and search unstructured content with petabytes of data. With this updated fifth edition, you'll cover comprehensive recipes relating to what's new in Elasticsearch 8.x and see how to create and run complex queries and analytics. The recipes will guide you through performing index mapping, aggregation, working with queries, and scripting using Elasticsearch. You'll focus on numerous solutions and quick techniques for performing both common and uncommon tasks such as deploying Elasticsearch nodes, using the ingest module, working with X-Pack, and creating different visualizations. As you advance, you'll learn how to manage various clusters, restore data, and install Kibana to monitor a cluster and extend it using a variety of plugins. Furthermore, you'll understand how to integrate your Java, Scala, Python, and big data applications such as Apache Spark and Pig with Elasticsearch and create efficient data applications powered by enhanced functionalities and custom plugins. By the end of this Elasticsearch cookbook, you'll have gained in-depth knowledge of implementing the Elasticsearch architecture and be able to manage, search, and store data efficiently and effectively using Elasticsearch.

Setting up networking

Correctly setting up networking is very important for your nodes and cluster.

There are a lot of different installation scenarios and networking issues. The first step for configuring the nodes in order to build a cluster is to correctly set the node discovery.

Getting ready

To change configuration files, you will need a working Elasticsearch installation and a simple text editor, as well as your current networking configuration (your IP address).

How to do it…

To set up the networking, use the following steps:

  1. Use a standard Elasticsearch configuration config/elasticsearch.yml file; your node will be configured to bind on the localhost interface (by default) so that it can't be accessed by external machines or nodes.
  2. To allow another machine to connect to our node, we need to set network.host to our IP address (for example, I have 192.168.1.164).
  3. To be able to discover other nodes, we need to list them in the ...
