ElasticSearch+Kibana+Packetbeat

一、介绍
Packetbeat 是一个实时网络数据包分析工具，通过嗅探应用服务器之间的网络通讯，来解码应用层协议类型如HTTP、MySQL、redis等等，关联请求与响应，并记录每个事务有意义的字段。
Kibana是一个分析与可视化平台，设计出来用于和Elasticsearch一起使用的。你可以用kibana搜索、查看、交互存放在Elasticsearch索引里的数据，使用各种不同的图表、表格、地图等kibana能够很轻易地展示高级数据分析与可视化。
ElasticSearch是一个开源的分布式搜索引擎，具备高可靠性，支持非常多的企业级搜索用例。像Solr4一样，是基于Lucene构建的。支持时间时间索引和全文检索。

二、系统要求：Java环境

三、安装步骤
安装ElasticSearch
1.下载解压
2../bin/elasticsearch
如果是用root账号启动，会报以下错误
java.lang.RuntimeException: can not run elasticsearch as root
3.添加普通用户elsearch

[root@localhost bin]# groupadd elsearch
[root@localhost bin]# useradd elsearch -g elsearch 
[root@localhost local]# chown -R elsearch:elsearch elasticsearch-5.3.1/
[root@localhost logs]# su elsearch
[elsearch@localhost logs]$ cd /usr/local/elasticsearch-5.3.1/bin/cd elasticsearch/bin
[elsearch@localhost bin]$./elasticsearch -d

启动后打印信息如下
