基于Centos7系统一键部署EFK服务

脚本内容大家看一下function就行了..

EFK采用集中式的日志管理架构

elasticsearch：一个开源分布式搜索引擎，提供搜集、分析、存储数据三大功能。它的特点有：分布式，零配置，自动发现，索引自动分片，索引副本机制，restful风格接口，多数据源，自动搜索负载等。

kibana：可以为Logstash 、Beats和ElasticSearch提供友好的日志分析Web 界面，可以帮助汇总、分析和搜索重要数据日志。

filebeat：轻量级日志采集器。需要在每个应用服务器配置filebeat，来采集日志，并输出到elasticsearch。
