ELKStack简介
        对于日志来说，最常见的需求就是收集、存储、查询、展示，开源社区正好有相对应的开源项目：logstash（收集）、elasticsearch（存储+搜索）、kibana（展示），我们将这三个组合起来的技术称之为ELKStack，所以说ELKStack指的是Elasticsearch、Logstash、Kibana技术栈的结合，一个通用的架构如下图所示：

 

系统环境：Centos 7.4  JDK 1.8

Elasticsearch6.0安装:

1、安装JDK

[[email protected] elasticsearch]# yum install -y java
[[email protected] elasticsearch]# java -version
openjdk version "1.8.0_65"
OpenJDK Runtime Environment (build 1.8.0_65-b17)
OpenJDK 64-Bit Server VM (build 25.65-b01, mixed mode)

2、安装Elasticsearch6.0

[[email protected] elasticsearch]# wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.0.0.rpm

3、修改配置文件

[[email protected] elasticsearch]# vim /etc/elasticsearch/elasticsearch.yml
cluster.name: jypay-es
node.name: es-jypay-1
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
bootstrap.memory_lock: true
network.host: 192.168.6.222
http.port: 9200

4、启动并测试

启动：
[[email protected] elasticsearch]# systemctl start  elasticsearch.service

测试，看到如下打印信息表示服务正常启动：
[[email protected] elasticsearch]# curl http://192.168.6.222:9200

  "cluster_name" : "jypay-es",
