1. 节点信息查看

#查看集群健康情况
curl -X GET 'localhost:9200/_cat/health?v&pretty'#查看节点信息
curl -X GET 'localhost:9200/_cat/nodes?v&pretty' 

2. 索引管理

在es中，索引就相当于是mysql中的库了。

#查看索引列表
curl -X GET 'localhost:9200/_cat/indices?v&pretty'# 创建index 
curl -X PUT 'localhost:9200/customer?pretty'
curl -X PUT 'localhost:9200/users?pretty'#删除索引
curl -X PUT 'localhost:9200/users?pretty'
curl -X GET 'localhost:9200/_cat/indices?v&pretty'
#删除索引
curl -X DELETE 'localhost:9200/users?pretty'

可以看到我们创建了users 这个索引，然后删除这个users 这个索引对象，

3. 文档管理

3.1 文档添加

文档添加的愈发是/index/type/id 其中，index是索引名称，type就相当于是mysql中的哪张表了。

# 添加文档
#当customer这个文档不存在得情况，就会自动创建这个索引
#-d 数据类型
#-H 添加Head 头
#-XPUT put提交方式
#external/1
curl -X PUT 'localhost:9200/customer/external/1?pretty&pretty' -d '{"name": "John Doe"}'  -H "Content-Type:application/json"
curl -X PUT 'localhost:9200/customer/external/2?pretty&pretty' -d '{"name": "yellowcong"}'  -H "Content-Type:application/json"#查询
#查询id为1得
curl -X GET 'localhost:9200/customer/external/1?pretty&pretty'

可以看到文档的类型是"_type" : “external”

3.2 文档更新

这个地方external ，有点像mysql中每条记录得id信息

# 插入文档
curl -X PUT 'localhost:9200/customer/external/1?pretty&pretty' -d '{"name": "yellowcong2","age":12}'  -H "Content-Type:application/json"#获取列表
curl -X GET 'localhost:9200/customer/external/3?pretty&pretty'#直接通过post /put 覆盖更新文档
curl -X PUT 'localhost:9200/customer/external/1/?pretty&pretty' -d '{"name": "yellowcong2","age":12}'  -H "Content-Type:application/json"#通过update 接口进行更新
curl -XPOST 'localhost:9200/customer/external/1/_update?pretty&pretty' -d'
{"doc": { "name": "张三","age":12 }
}'  -H "Content-Type:application/json"#更新某个字段，比如age 这种 ，ctx._source 表示原文档
curl -XPOST 'localhost:9200/customer/external/1/_update?pretty&pretty' -d'
{"script" : "ctx._source.age += 5"
}'  -H "Content-Type:application/json"#更新名称
curl -XPOST 'localhost:9200/customer/external/1/_update?pretty&pretty' -d'
{"script" : "ctx._source.name = \"张2\""
}'  -H "Content-Type:application/json"

3.3 文档删除

#删除文档
curl -X DELETE 'localhost:9200/customer/external/1?pretty'  

3.4 文档批处理

#删除文档customer 
curl -X DELETE 'localhost:9200/customer?pretty'#批量插入数据,两条
curl -XPOST 'localhost:9200/customer/external/_bulk?pretty' -d'
{"index":{"_id":"5"}}
{"name": "John Doe" }
{"index":{"_id":"6"}}
{"name": "Jane Doe" }
' -H  "Content-Type:application/json"#查看列表
curl 'localhost:9200/customer/_search?pretty'#批量更新和删除
curl -XPOST 'localhost:9200/customer/external/_bulk?pretty' -d'
{"update":{"_id":"5"}}
{"doc": { "name": "John Doe becomes Jane Doe" } }
{"delete":{"_id":"6"}}
' -H  "Content-Type:application/json"#查看索引
curl 'localhost:9200/customer/external/5

批量插入两条数据

查看插入的数据

4 搜索

4.1 查询所有数据

#查看customer得所有数据
curl -XGET 'localhost:9200/customer/_search?pretty'#这个q就相当于是查询条件
curl -XGET 'localhost:9200/customer/_search?q=*&pretty'#第三种查询所有得写法
curl -X GET 'localhost:9200/customer/_search?pretty' -d'
{"query": { "match_all": {} }
}'

4.2 分页查询

#删除之前的文档
curl -X DELETE 'localhost:9200/customer?pretty' #批量插入数据,插入六条数据
curl -XPOST 'localhost:9200/customer/external/_bulk?pretty' -d'
{"index":{"_id":"1"}}
{"name": "yellowcong","age":12 }
{"index":{"_id":"2"}}
{"name": "李二" ,"age":65}
{"index":{"_id":"3"}}
{"name": "张三" ,"age":22}
{"index":{"_id":"4"}}
{"name": "赵四","age":18 }
{"index":{"_id":"5"}}
{"name": "王五","age":30 }
{"index":{"_id":"6"}}
{"name": "赵六","age":20 }
' -H  "Content-Type:application/json"#查看所有
curl -X GET 'localhost:9200/customer/_search?pretty'#分页查询,排序方式通过_id ,页面大小为2
#query 查询条件
#sort 排序方式
#from 开始页面
#size 页面大小
curl -XGET 'localhost:9200/customer/_search?pretty' -d'
{"query": { "match_all": {} },"sort": { "_id": { "order": "asc" } },"from": 0,"size": 2
}' -H  "Content-Type:application/json"#返回指定的字段，通过_source 指定只需要返回的字段
curl -XGET 'localhost:9200/customer/_search?pretty' -d'
{"query": { "match_all": {} },"_source": [ "name"]
}' -H  "Content-Type:application/json"

4.3 按条件查询

#与查询
curl -XGET 'localhost:9200/customer/_search?pretty' -d'
{"query": { "match_all": {"name":"yellowcong"} },"sort": { "_id": { "order": "asc" } }
}' -H  "Content-Type:application/json"#或查询must，should，和 must_not
