This article introduces the knowledge of "script sharing for one-click deployment of EFK services based on Centos7 system". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Architecture

EFK adopts a centralized log management architecture

Elasticsearch: an open source distributed search engine that provides three functions of collecting, analyzing and storing data. Its features are: distributed, zero configuration, automatic discovery, automatic index slicing, index copy mechanism, restful style interface, multiple data sources, automatic search load and so on.

Kibana: provides a friendly log analysis Web interface for Logstash, Beats, and ElasticSearch to help summarize, analyze, and search important data logs.

Filebeat: lightweight log collector. Filebeat needs to be configured on each application server to collect logs and output to elasticsearch

Deploy the KIBANA script with one click
