es 9300 端口怎么修改 es的9300端口

elasticsearch教程


注意:


1、elasticsearch的rest默认端口为9200,客户端的默认端口为9300,也就是,java编程连接的端口为9300



命令模式:


curl -<REST Verb> <Node>:<Port>/<Index>/<Type><ID>



返回字段说明:


- took —— Elasticsearch执行这个搜索的耗时,以毫秒为单位


- timed_out —— 指明这个搜索是否超时


- _shards —— 指出多少个分片被搜索了,同时也指出了成功/失败的被搜索的shards的数量


- hits —— 搜索结果


- hits.total —— 能够匹配我们查询标准的文档的总数目


- hits.hits —— 真正的搜索结果数据(默认只显示前10个文档)


- _score和max_score —— 现在先忽略这些字段



1、检查集群健康


curl 'localhost:9200/_cat/health?v'



2、获得节集群中的节点列表


curl 'localhost:9200/_cat/nodes?v'



3、列出所有的索引


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



4、创建一个索引customer


curl -XPUT 'localhost:9200/customer?pretty'


说明:索引index相当于一个库,pretty附加到调用的尾部,使其以美观的形式打印出JSON响应(如果有的话),不添加pretty也会打印结果,只是不美观



5、在customer索引下创建一个文档external(添加一个记录)


curl -XPUT '192.168.60.128:9200/customer/external/1?pretty' -d '


{


"name": "John Doe"


}'


说明:文档type相当于一个表



curl -XPOST 'localhost:9200/customer/external?pretty' -d '


{


"name": "Jane Doe"


}'   


注意,在上面的情形中,由于我们没有指定一个ID,我们使用的是POST而不是PUT



6、数据查询


查询一个id=1的数据


curl -XGET '192.168.60.128:9200/customer/external/1?pretty'


查询external下所有的数据


curl -XGET '192.168.60.128:9200/customer/external/_search?pretty'


查询customer下所有的数据


curl -XGET '192.168.60.128:9200/customer/_search?pretty'


查询所有数据


curl -XGET '192.168.60.128:9200/_search?pretty'



7、删除一个索引


curl -XDELETE '192.168.60.128 :9200/customer?pretty'



8、修改文档(数据)


curl -XPUT '192.168.60.128:9200/customer/external/1?pretty' -d '


{


"name": "Tom"


}'



curl -XPOST '192.168.60.128 :9200/customer/external/1/_update?pretty' -d '


{


"doc": { "name": "Jane Doe", "age": 20 }


}'



curl -XPOST '192.168.60.128 :9200/customer/external/1/_update?pretty' -d '


{


"script" : "ctx._source.age += 5"


}'



9、删除文档(数据)


curl -XDELETE '192.168.60.128 :9200/customer/external/1?pretty'



删除符合某个查询条件的多个文档


curl -XDELETE 'localhost:9200/customer/external/_query?pretty' -d '


{


"query": { "match": { "name": "John" } }


}'



10、批处理


添加两个文档(ID 1 - John Doe and ID 2 - Jane Doe)


curl -XPOST '192.168.60.128 :9200/customer/external/_bulk?pretty' -d '


{"index":{"_id":"1"}}


{"name": "John Doe" }


{"index":{"_id":"2"}}


{"name": "Jane Doe" }



更新第一个文档(ID为1),然后删除第二个文档(ID为2):


curl -XPOST '192.168.60.128 :9200/customer/external/_bulk?pretty' -d '


{"update":{"_id":"1"}}


{"doc": { "name": "John Doe becomes Jane Doe" } }


{"delete":{"_id":"2"}}



11、导入json文件(导入数据)


curl -XPOST 'localhost:9200/bank/account/_bulk?pretty' --data-binary @accounts.json


accounts.json为一个存储着json数据的文件



12、请求体条件搜索


curl '192.168.60.128 :9200/bank/_search?q=*&pretty'


使用请求体方法的等价搜索是:


curl -XPOST '192.168.60.128 :9200/bank/_search?pretty' -d '


{


"query": { "match_all": {} }


}'



match(equal)条件查询,相当于select account_number,balance from bank.account where gender='M' order by balance desc limit 10,10


curl -XPOST '192.168.60.128 :9200/bank/account/_search?pretty' -d '


{


"_source": ["account_number", "balance"],


"query": { "match": {"gender":"M"} },


"sort": { "balance": { "order": "desc" } }


"from": 10,


"size": 10


}'



match_phrase(like)条件查询,相当于select * from bank.account where address like ‘%mill lane%’


注意:字符串匹配不分大小写


curl -XPOST '192.168.60.128 :9200/bank/account/_search?pretty' -d '


{


"query": { "match_phrase": { "address": "mill lane" } }


}'



must(and)条件查询,相当于select * from bank.account where address like "%mill%" and address like "%lane%"


返回包含“mill”和“lane”的所有的账户


curl -XPOST '192.168.60.128 :9200/bank/_search?pretty' -d '


{


"query": {


"bool": {


"must": [


{ "match": { "address": "mill" } },


{ "match": { "address": "lane" } }


]


}


}


}'



should(or)条件查询,相当于select * from bank.account where address like "%mill%" or address like "%lane%"


返回地址中包含“mill”或者“lane”的所有的账户


curl -XPOST '192.168.60.128 :9200/bank/_search?pretty' -d '


{


"query": {


"bool": {


"should": [


{ "match": { "address": "mill" } },


{ "match": { "address": "lane" } }


]


}


}


}'



must_not(not in)条件查询,相当于select * from bank.accout where id not in(select id from bank.account where address like "%mill%" or address like "lane")


返回地址中既不包含“mill”,同时也不包含“lane”的所有的账户信息


curl -XPOST '192.168.60.128 :9200/bank/_search?pretty' -d '


{


"query": {


"bool": {


"must_not": [


{ "match": { "address": "mill" } },


{ "match": { "address": "lane" } }


]


}


}


}'



返回40岁以上并且不生活在ID(daho)的人的账户


curl -XPOST '192.168.60.128 :9200/bank/_search?pretty' -d '


{


"query": {


"bool": {


"must": [


{ "match": { "age": "40" } }


],


"must_not": [


{ "match": { "state": "ID" } }


]


}


}


}'



过滤的查询,其返回值是越在20000到30000之间(闭区间)的账户


curl -XPOST '192.168.60.128 :9200/bank/_search?pretty' -d '


{


"query": {


"bool": {


"must": {


"match_all": {}


},


"filter": {


"range": {


"balance": {


"gte": 20000,


"lte": 30000


}


}


}


}


}


}



聚合,group by


' -d '


{


"properties": {


"state": {


"type": "text",


"fielddata": true


}


}


}'



统计每个state有多少条记录


将size设置成0,这样就可以只看到聚合结果了,而不会显示命中的结果


curl -XPOST '192.168.60.128 :9200/bank/_search?pretty=true ' -d '


{


"size":0,


"aggs": {


"group_by_state": {


"terms": {


"field": "state"


}


}


}


}'



计算了每个州的账户的平均余额(还是按照账户数量倒序排序的前10个州)


curl -XPOST '192.168.60.128 :9200/bank/_search?pretty' -d '


{


"size": 0,


"aggs": {


"group_by_state": {


"terms": {


"field": "state",


"order": {


"average_balance": "desc"


}


},


"aggs": {


"average_balance": {


"avg": {


"field": "balance"


}


}


}


}


}


}'



使用年龄段(20-29,30-39,40-49)分组,然后在用性别分组,然后为每一个年龄段的每一个性别计算平均账户余额


curl -XPUT "http://192.168.60.128:9200/bank/_mapping/account" -d'


{


"properties": {


"gender": {


"type": "text",


"fielddata": true


}


}


}'



curl -XPOST 'localhost:9200/bank/_search?pretty' -d '


{


"size": 0,


"aggs": {


"group_by_age": {


"range": {


"field": "age",


"ranges": [


{


"from": 20,


"to": 30


},


{


"from": 30,


"to": 40


},


{


"from": 40,


"to": 50


}


]


},


"aggs": {


"group_by_gender": {


"terms": {


"field": "gender"


},


"aggs": {


"average_balance": {


"avg": {


"field": "balance"


}


}


}


}


}


}


}


}



curl -XPOST '192.168.60.128 :9200/bank/account/_bulk?pretty' --data-binary @accounts.json


curl '192.168.60.128 :9200/_cat/indices?v'




13、IK中文分词器使用


curl -XPUT http://192.168.60.128:9200/ik


curl -XPOST http://192.168.60.128:9200/ik/fulltext/_mapping -d'{ "fulltext": { "_all": { "analyzer": "ik_max_word", "search_analyzer": "ik_max_word", "term_vector": "no", "store": "false" }, "properties": { "content": { "type": "text", "analyzer": "ik_max_word", "search_analyzer": "ik_max_word", "include_in_all": "true", "boost": 8 } } }}'



curl -XPOST http://192.168.60.128:9200/ik/fulltext/1 -d'


{"content":"美国留给伊拉克的是个烂摊子吗"}'


curl -XPOST http://192.168.60.128:9200/ik/fulltext/2 -d'


{"content":"公安部:各地校车将享最高路权"}'


curl -XPOST http://192.168.60.128:9200/ik/fulltext/3 -d'


{"content":"中韩渔警冲突调查:韩警平均每天扣1艘中国渔船"}'


curl -XPOST http://192.168.60.128:9200/ik/fulltext/4 -d'


{"content":"中国驻洛杉矶领事馆遭亚裔男子枪击 嫌犯已自首"}'



curl -XPOST http://192.168.60.128:9200/ik/fulltext/_search -d'{ "query" : { "match" : { "content" : "中国" }}, "highlight" : { "pre_tags" : ["<tag1>", "<tag2>"], "post_tags" : ["</tag1>", "</tag2>"], "fields" : { "content" : {} } }}'
