ELK自动安装脚本

**一、简介**

ELK由Elasticsearch、Logstash和Kibana三部分组件组成；

Elasticsearch是个开源分布式搜索引擎，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。

Logstash是一个完全开源的工具，它可以对你的日志进行收集、分析，并将其存储供以后使用

kibana 是一个开源和免费的工具，它可以为 Logstash 和 ElasticSearch 提供的日志分析友好的 Web 界面，可以帮助您汇总、分析和搜索重要数据日志。

**二、核心组件**

Logstash: logstash server端用来搜集日志；

Elasticsearch: 存储各类日志；

Kibana: web化接口用作查寻和可视化日志；

Filebeat是一个日志文件托运工具，在你的服务器上安装客户端后，filebeat会监控日志目录或者指定的日志文件，追踪读取这些文件（追踪文件的变化，不停的读），并且转发这些信息到elasticsearch或者logstarsh中存放。

**三、安装脚本**
