篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了centos6搭建elk相关的知识，希望对你有一定的参考价值。
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。
四大组件
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；
Logstash Forwarder: logstash client端用来通过lumberjack 网络协议发送日志到logstash server；
实验环境

vim /var/www/html/kibana/config.js
elasticsearch: "http://"+window.location.hostname+":9200"
elasticsearch: "http://192.168.31.243:9200", 修改为
vim /usr/local/elasticsearch/config/elasticsearch.yml
http.cors.enabled: true 配置文件最后加载一行
/usr/local/elasticsearch/bin/service/elasticsearch restart 重启读取配置文件
service httpd restart
