• 安装

  $ docker pull docker.elastic.co/elasticsearch/elasticsearch:7.10.0 # 获取镜像$ docker run -d -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:7.10.0 # 启动单节点容器$ curl "127.0.0.1:9200" # 确认容器启动正常

• 常用命令

• 使用示例

  在中经常看到这样的介绍:

  GET /_cat/health?v

  翻译过来,实际使用中,是要在bash 命令行(以Linux为例) 中输入以下命令:

  curl -X GET localhost:9200/_cat/health?v

  其中localhost:9200指的是所安装的elasticsearch对外开放的接口。

  curl -X
       
         '
        
         ://
         
          :
          
           /
           
            ?
            
             ' -d ''
            
           
          
         
        
       

  <PATH> means the API endpoint.

• 命令解释

• 状态管理

  • 查看节点状态

  the cat APIs return information about your cluster：

  GET /_cat/health?v

  查看index

  curl "localhost:9200/_cat/indices?v"

• 存储数据

  • 存入数据

  curl -X PUT localhost:9200/customer/_doc/1?pretty -H 'Content-Type:application/json' -d '{"name":"Jonh Doe"}'

  customer : index

  _doc : type

  1 : unique document ID

  name : fileds

  • 向多个index写入数据

  curl -X POST "localhost:9200/_bulk?pretty" -H 'Content-Type: application/json' -d'{ "index" : { "_index" : "test", "_id" : "1" } }{ "field1" : "value1" }{ "delete" : { "_index" : "test", "_id" : "2" } }{ "create" : { "_index" : "test", "_id" : "3" } }{ "field1" : "value3" }{ "update" : {"_id" : "1", "_index" : "test"} }{ "doc" : {"field2" : "value2"} }'

  • 通过文件批量写入

  curl -H "Content-Type: application/json" -XPOST "localhost:9200/bank/_bulk?pretty&refresh" --data-binary "@accounts.json"

• 查看数据

  • Information retrieve

  curl localhost:9200/customer/_doc/1?pretty

  • _search查询数据

  curl -X GET "localhost:9200/bank/_search?pretty" -H 'Content-Type: application/json' -d'{  "query": { "match_all": {} },  "sort": [    { "account_number": "asc" }  ]}'curl -XGET localhost:9200/bank/_search?pretty -H "Content-Type: application/json" -d '{"query":{"match":{"address":"mill lane"}}}'curl -XGET localhost:9200/bank/_search?pretty -H "Content-Type: application/json" -d '{"query":{"match_phrase":{"address":"mill lane"}}}'

  query : 查询

  ​ match : 查询单词

  ​ match_phrase : 查询短语

  ​ match_all : 查询所有

  sort ： 排序
