We can use these packages to install the Elasticsearch software. This comes under the Elastic license, where we can freely use the open source part while commercial features can be used by starting a free 30-day trial duration. On the Elastic downloads page, we can get the latest stable version of Elasticsearch. If we want to install any specific version, then we can do so from the past releases page of the Elastic website. We require Java 8 or later to install Elasticsearch.
