elasticsearch cluster

First, IntroductionElasticsearch is a Lucene-based search server. It provides a distributed multi-user-capable full-text search engine, based on a restful web interface. Elasticsearch is a popular enterprise-class search engine developed in Java and published as an open source under the Apache license terms. Designed for cloud computing, it can achieve real-time search, stable, reliable, fast, easy to install and use.Second,

The _cat parameter allows you to see some information about the cluster, such as whether the cluster is healthy, what nodes it has, and what the index is.Detecting Cluster HealthCurl Localhost:9200/_cat/health?v Description: Curl is a file transfer tool that works under the command line using URL syntax 9200 Access the port number o

Elasticsearch-head is a elasticsearch cluster management tool, which is a standalone web program written entirely by HTML5, and you can integrate it into ES via plugins. or directly download the source code, open index.html locally to run it. The GIT address for this tool is: Https://github.com/Aconex/elasticsearch-hea

Elasticsearch provides a very comprehensive and powerful rest API that you can use to interact with your cluster. The few things you can do with the API are as follows: Check your cluster, node, and index health status and statistics Managing cluster, node, and index data and metadata Perform crud (Cre

Elasticsearch is a very popular full-text search engine, but online tutorials are mostly used for the first time, and there are no advanced usage demos. This encounter need to cross-network segment network problems, their own exploration of the document for a long time, found to be feasible, so began to do an experiment, the final experiment success. Automatic discovery and networking are implemented under cross-network segments.A total of three nodes

Nodes in a multi-machine cluster can be divided into master nodes and data nodes, using the Zen Discovery (Zen discovery) mechanism in the configuration file to manage different nodes. Zen Discovery is the default discovery mechanism that comes with ES, using multicast to discover other nodes. As soon as you start a new ES node and set the same name as the cluster, the node is added to the cluster.Select 19
