ElasticSearch是一个基于Lucene的搜索服务器。它提供了一个分布式多用户能力的全文搜索引擎,基于RESTful web接口。Elasticsearch是用Java开发的,并作为Apache许可条款下的开放源码发布,是当前流行的企业级搜索引擎。 -----百度百科
而ElasticSearch-head就是一款能连接ElasticSearch搜索引擎,并提供可视化的操作页面对ElasticSearch搜索引擎进行各种设置和数据检索功能的管理插件,如在head插件页面编写RESTful接口风格的请求,就可以对ElasticSearch中的数据进行增删改查、创建或者删除索引等操作。类似于使用navicat工具连接MySQL这种关系型数据库,对数据库做操作。
简而言之:ElasticSearch-head就是一个针对es可视化操作的插件。
(1) 下载node:
① 下载地址:https://nodejs.org/en/download/
② 检查是否安装成功:Win+R CMD输入“node -v”命令检查,如果输出了版本号,则node安装成功。
(2) 安装grunt:
① CMD中执行“npm install -g grunt-cli”命令等待安装完成
② 输入:grunt -version命令检查是否安装成功
(1) 下载地址:https://github.com/mobz/elasticsearch-head
(2) 下载完成后,解压,打开elasticsearch-head-master文件夹,
修改Gruntfile.js文件,添加hostname:‘*’, 如图:
(3) 输入 cd elasticsearch-head
npm install
(4) 输入 npm run start 启动服务
(5) 验证:http://localhost:9100/ 安装成功
(6) 如果无法发现ES节点,尝试在ES配置文件中设置允许跨域
http.cors.enabled: true
http.cors.allow-origin: “*”
安装完后,默认head插件的web端口为9100,ElasticSearch服务的端口为9200,使用浏览器访问head地址,如http://IP地址:9100/,
2:聚合查询
注:这里的操作已经和restapi操作一模一样了,在此可以参看我的这篇文章Elasticsearch-02-es的restapi使用
Kibana是一个针对Elasticsearch的开源分析及可视化平台,使用Kibana可以查询、查看并与存储在ES索引的数据进行交互操作,使用Kibana能执行高级的数据分析,并能以图表、表格和地图的形式查看数据。

# Kibana is served by a back end server. This setting specifies the port to use.
# 服务端口号
server.port: 5601
# Specifies the address to which the Kibana server will bind. IP addresses and host names are both valid values.
# The default is 'localhost', which usually means remote machines will not be able to connect.
# To allow connections from remote users, set this parameter to a non-loopback address.
# 允许访问的IP,如果允许任何IP访问此处输入0.0.0.0
server.host: "localhost"
# Enables you to specify a path to mount Kibana at if you are running behind a proxy.
# Use the `server.rewriteBasePath` setting to tell Kibana if it should remove the basePath
# from requests it receives, and to prevent a deprecation warning at startup.
# This setting cannot end in a slash.
#server.basePath: ""
# Specifies whether Kibana should rewrite requests that are prefixed with
# `server.basePath` or require that they are rewritten by your reverse proxy.
# This setting was effectively always `false` before Kibana 6.3 and will
# default to `true` starting in Kibana 7.0.
#server.rewriteBasePath: false
# The maximum payload size in bytes for incoming server requests.
#server.maxPayloadBytes: 1048576
# The Kibana server's name. This is used for display purposes.
# 服务名称
server.name: "kibana"
# The URLs of the Elasticsearch instances to use for all your queries.
# ES服务地址
elasticsearch.hosts: ["http://localhost:9200"]
# When this setting's value is true Kibana uses the hostname specified in the server.host
# setting. When the value of this setting is false, Kibana uses the hostname of the host
# that connects to this Kibana instance.
#elasticsearch.preserveHost: true
# Kibana uses an index in Elasticsearch to store saved searches, visualizations and
# dashboards. Kibana creates a new index if the index doesn't already exist.
# 创建的索引
#kibana.index: ".kibana"
# The default application to load.
#kibana.defaultAppId: "home"
# If your Elasticsearch is protected with basic authentication, these settings provide
# the username and password that the Kibana server uses to perform maintenance on the Kibana
# index at startup. Your Kibana users still need to authenticate with Elasticsearch, which
# is proxied through the Kibana server.
# 登录ES使用的用户名和密码
#elasticsearch.username: "kibana"
#elasticsearch.password: "pass"
# Enables SSL and paths to the PEM-format SSL certificate and SSL key files, respectively.
# These settings enable SSL for outgoing requests from the Kibana server to the browser.
#server.ssl.enabled: false
#server.ssl.certificate: /path/to/your/server.crt
#server.ssl.key: /path/to/your/server.key
# Optional settings that provide the paths to the PEM-format SSL certificate and key files.
# These files are used to verify the identity of Kibana to Elasticsearch and are required when
# xpack.security.http.ssl.client_authentication in Elasticsearch is set to required.
#elasticsearch.ssl.certificate: /path/to/your/client.crt
#elasticsearch.ssl.key: /path/to/your/client.key
# Optional setting that enables you to specify a path to the PEM file for the certificate
# authority for your Elasticsearch instance.
#elasticsearch.ssl.certificateAuthorities: [ "/path/to/your/CA.pem" ]
# To disregard the validity of SSL certificates, change this setting's value to 'none'.

这里的操作和restapi是一样的,好处是有自动提示,具体更多操作可以参考我的另一篇文章:
