PS：6.3 开始 ElasticSearch 自身已经支持SQL查询。

github地址：https://github.com/NLPchina/elasticsearch-sql

一、在线安装

直接执行

./bin/elasticsearch-plugin install https://github.com/NLPchina/elasticsearch-sql/releases/download/6.3.2.0/elasticsearch-sql-6.3.2.0.zip

二、离线安装

下载离线安装包，放在es目录下

[es@jast elasticsearch-6.3.2]$ pwd
/home/es/elasticsearch-6.3.2
[es@jast elasticsearch-6.3.2]$ wget https://github.com/NLPchina/elasticsearch-sql/releases/download/6.3.2.0/elasticsearch-sql-6.3.2.0.zip

安装

./bin/elasticsearch-plugin install file:/home/es/elasticsearch-6.3.2/elasticsearch-sql-6.3.2.0.zip

   

查看是否安装成功

进入es插件目录查看，是否有相应jar包

[es@jast elasticsearch-6.3.2]$ cd plugins/
[es@jast plugins]$ ls
sql
[es@jast plugins]$ pwd
/home/es/elasticsearch-6.3.2/plugins
[es@jast plugins]$ ls sql/
druid.jar                      parent-join-client-6.3.2.jar
elasticsearch-sql-6.3.2.0.jar  plugin-descriptor.properties
guava.jar                      reindex-client-6.3.2.jar

重启服务

在Kibana中访问方法为：GET _sql?sql=SELECT * FROM TABLENAME

浏览器访问方法为：http://ip:9200/_sql?sql=SELECT * FROM TABLENAME

三、ElasticSearch SQL 可视化工具

下载服务(支持6.x版本)

wget http://github.com/NLPchina/elasticsearch-sql/releases/download/5.4.1.0/es-sql-site-standalone.zip

解压下载文件，并安装服务

[es@jast el_sql]$ cd site-server/
[es@jast site-server]$ ls
node-server.js  package.json  site_configuration.json
[es@jast site-server]$ npm install express --save

 修改默认端口

[es@jast es-web]$ vim site-server/site_configuration.json 
{"port":5602
}

执行服务

node node-server.js

访问页面可以直接执行sql了

ps: 7.x http查询方法，使用post查询
