ES、kibana安装及交互操作

一、ES的安装与启动

1、ES安装（Windows环境）

• 下载地址：https://www.elastic.co/cn/downloads/past-releases#elasticsearch
• 版本：6.3.2
• 运行环境：jdk1.8以上
• 双击.bat启动

2、查看效果

浏览器输入：http://localhost:9200，返回如下json。

{
  "name" : "RDFnj43",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "X-h3NABsTPOitRIeqIJj4Q",
  "version" : {
    "number" : "6.3.2",
    "build_flavor" : "default",
    "build_type" : "zip",
    "build_hash" : "053779d",
    "build_date" : "2018-07-20T05:20:23.451332Z",
    "build_snapshot" : false,
    "lucene_version" : "7.3.1",
    "minimum_wire_compatibility_version" : "5.6.0",
    "minimum_index_compatibility_version" : "5.0.0"
  },
  "tagline" : "You Know, for Search"
}

证明启动成功

二、kibana安装及启动

1、kibana安装（Windows环境）

• 下载地址：https://www.elastic.co/cn/downloads/past-releases#kibana
• 版本：6.3.2
• 运行环境：jdk1.8以上
• 双击.bat启动

2、查看效果

浏览器输入：http://localhost:5601，如下所示，证明启动成功

三、交互操作

1、ES与mysql的对应关系理解

2、使用postman与ES交互操作案例

Get 查看所有索引

localhost:9200/_all

PUT 创建索引-test

localhost:9200/test  

DEL 删除索引-test

localhost:9200/test  

PUT 创建索引-person-1

localhost:9200/person

PUT 新增数据-person-1

localhost:9200/person/_doc/1

{
    "first_name" : "John",
  "last_name" : "Smith",
  "age" : 25,
  "about" : "I love to go rock climbing",
  "interests" : [ "sports", "music" ]
}

PUT 新增数据-person-2

localhost:9200/person/_doc/2

{
    "first_name" : "Eric",
  "last_name" : "Smith",
  "age" : 23,
  "about" : "I love basketball",
  "interests" : [ "sports", "reading" ]
}

GET 搜索数据-person-id

localhost:9200/person/_doc/1

GET 搜索数据-person-name

localhost:9200/person/_doc/_search?q=first_name:john

{
  "took": 56,
  "timed_out": false,
  "_shards": {
    "total": 1,
    "successful": 1,
    "skipped": 0,
    "failed": 0
  },
  "hits": {
    "total": {
      "value": 1,
      "relation": "eq"
    },
    "max_score": 0.6931472,
    "hits": [
      {
        "_index": "person",
        "_type": "_doc",
        "_id": "1",
        "_score": 0.6931472,
        "_source": {
          "first_name": "John",
          "last_name": "Smith",
          "age": 25,
          "about": "I love to go rock climbing",
          "interests": [
            "sports",
            "music"
          ]
        }
      }
    ]
  }
}

• GET为查询操作
• PUT为创建索引
• DELETE为删除索引

3、使用kibana与ES交互操作

找到dev tools，进行交互操作

//查询所有的索引
GET _all1
//按照id查询
GET person/_doc/2

与es交互式操作格式：

POST /person/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "match": {
            "interests": "FOOTBALL"
          }
        },
        {
          "match": {
            "userName": "ESRC22"
          }
        }
      ]
    }
  }
}

• must为且的关系
• must处为should的时候为或的关系
