Elasticsearch is a Lucene-based search server. It provides a distributed multi-user-capable full-text search engine, based on a restful web interface. Elasticsearch was developed in Java and published as an open source under the Apache license terms, and is the second most popular enterprise search engine. Designed for cloud computing, it can achieve real-time search, stable, reliable, fast, easy to install
1 Installation Environment
Install the multi-machine ES cluster (distributed cluster), install an ES node in three servers respectively, and these three nodes form an ES cluster. Because it is a small cluster, setting these three nodes can be a master node and a data node. The server's IP is 192.168.1.111, 192.168.1.112, and 192.168.1.113, respectively.
When installing a stand-alone ES cluster, install three ES nodes on a single server 192.168.1.114.

Basic usage of Elasticsearch and cluster constructionFirst, IntroductionElasticsearch and SOLR are Lucene-based search engines, but Elasticsearch naturally supports distributed, While SOLR is a distributed version of Solrcloud after the 4.0 release, SOLR's distributed support requires zookeeper support.Here's a detailed comparison of Elasticsearch and SOLR: http:
Building real-time log collection system with Elasticsearch,logstash,kibanaIntroduction
