使用kibana对elasticsearch进行操作

1. 打开elasticsearch和kibana
2. 访问http://192.168.25.129:5601 （使用安装kibana的ip）
3. 使用Dev Tools(如下)
   

使用elasticsearch API实现CRUD

1. 添加索引

   
   #指定配置创建索引lib
   
   
   #lib为索引名称
   
   
   #"number_of_shards":3  分片数量为3
   
   
   #"number_of_replicas":0 备份数量为0
   
   PUT /lib/  
   {
       "settings":{
           "index":{
                   "number_of_shards":3,      
                   "number_of_replicas":0      
           }
       }
   }
   
   
   #使用默认配置创建索引lib2
   
   PUT lib2

2. 查询索引配置

   
   #查询lib的设置
   
   GET /lib/_settings
   
   
   #结果如下
   
   {
     "lib": {
       "settings": {
         "index": {
           "creation_date":     "1534492852386",
               "number_of_shards": "3",
               "number_of_replicas": "0",
           "uuid":     "XvO3MPUdQ-SMu-o    VZCGAWw",
           "version": {
             "created":   "6030299"
           },
           "provided_name":     "lib"
         }
       }
     }
   }
   
   
   #查询lib2设置
   
   GET /lib2/_settings
   
   
   #结果如下,可以看出,默认分片为5个,备份1个
   
   {
     "lib2": {
       "settings": {
         "index": {
           "creation_date":     "1534492911101",
               "number_of_shards": "5",
               "number_of_replicas": "1",
           "uuid":     "8DzDTWeeSHujmvb    RGAHg_g",
           "version": {
             "created":   "6030299"
           },
           "provided_name":     "lib2"
         }
       }
     }
   }
   
   
   #查询所有索引的配置
   
   GET _all/_settings
   

3. 添加文档

   
   #指定添加文档id为1
   
   
   #type为user,1是文档编号
   
   PUT /lib/user/1      
   {
       "first_name":"Jane",
       "last_name":"Smith",
       "age":32,
       "about":"I like to collect rock albums",
       "interests":["music"]
   }
   
   
   #结果
   
   {
     "_index": "lib",
     "_type": "user",
     "_id": "1",
     "_version": 1,
     "result": "created",
     "_shards": {
       "total": 1,
       "successful": 1,
       "failed": 0
     },
     "_seq_no": 0,
     "_primary_term": 1
   }
   
   
   #不指定id添加文档
   
   POST /lib/user/
   {
       "first_name":"Douglas",
       "last_name":"Fir",
       "age":23,
       "about":"I like to build cabinets",
       "interests":["forestry"]
   }
   
   
   #结果如下,id由elasticsearch生成
   
   {
     "_index": "lib",
     "_type": "user",
     "_id":   "mJP7RmUBx8NiZecJ2McD"  ,
     "_version": 1,
     "result": "created",
     "_shards": {
       "total": 1,
       "successful": 1,
       "failed": 0
     },
     "_seq_no": 0,
     "_primary_term": 1
   }

4. 文档的查询

   
   #查询id为1的文档
   
   GET /lib/user/1
   
   
   #结果
   
   {
     "_index": "lib",
     "_type": "user",
     "_id": "1",
     "_version": 1,
     "found": true,
     "_source": {
       "first_name":"Jane",
       "last_name":"Smith",
       "age": 32,
       "about": "I like to collect rock albums",
       "interests": [
         "music"
       ]
     }
   }
   
   
   #查询不指定id添加的文档
   
   GET /lib/user/mJP7RmUBx8NiZecJ2McD
   
   
   #结果
   
   {
     "_index": "lib",
     "_type": "user",
     "_id":   "mJP7RmUBx8NiZecJ2McD"  ,
     "_version": 1,
     "found": true,

       "interests": [
         "forestry"
       ]
     }
   }
   
   
   #指定查询的字段
   
   GET /lib/user/1?_source=age,about
   
   //结果
   {
     "_index": "lib",
     "_type": "user",
     "_id": "1",
     "_version": 1,
     "found": true,
     "_source": {
       "about": "I like to collect rock albums",
       "age": 32
     }
   }

5. 更新文档

   
   #直接覆盖原文档
   
   PUT /lib/user/1

       "last_name":"Smith",
       "age":36,
       "about":"I like to collect rock albums",
       "interests":["music"]
   }
   
   
   #修改指定字段(注意使用的是POST，推荐使用该方式)
