一、指令部分:1.search管理界面地址: http://172.20.230.110:9200/_plugin/head/
2.集群状态查看命令: curl -XGET 'localhost:9200/_cluster/health?pretty' curl -XGET 'localhost:9200/_cat/health?v' 检查shards unsigned原因 curl 'localhost:9200/_cat/shards?h=index,shard,prirep,state,docs,store,ip,node,un*&v' | grep UNAS 检查shards unsigned原因 curl -XGET localhost:9200/_cat/shards?v | grep UNA3.查看集群的节点数目和主节点等信息,如下: curl -XGET 'localhost:9200/_cat/nodes?v'
4.查看index的索引信息: curl -XGET 'localhost:9200/lxj.test_es_comm/_settings?pretty' curl -XGET 'localhost:9200/_clus ter/health/employee?pretty' (查看索引健康状态) curl -XGET 'localhost:9200/_cluster/health/?level=indices&pretty'(查看全部索引的健康状态) curl -XGET 'localhost:9200/_cluster/health/?level=shards&pretty' (查看分片级别的健康状态)
curl -XPOST 'localhost:9200/lxj.test_es_comm/_open?v'(索引打开) curl -XPOST 'localhost:9200/lxj.test_es_comm/_close?v' (索引关闭) curl -s 'localhost:9200/_cat/indices?v' |grep red (查看red状态的索引)5.查看index的表结构: curl -XGET 'localhost:9200/default.test_people_es/_mappings?pretty'
6.通过Curl使用RestAPI的格式: curl -X<VERB> '<HOST>:9200/<PATH>/[<API>]/[?<PARAMETERS>]' [-d '{<BODY>}']
7.创建index: curl -XPUT '172.20.230.110:9200/test/?pretty'
删除index: curl -XDELETE 'localhost:9200/test/?pretty'
8.编入文档:(如果有会覆盖) curl -XPUT 'localhost:9200/employee/dev/1?pretty' -d '{ "firstname": "San", "lastname": "Zhang", "age": 26, "on_board_date": "2015-10-31", "hometown": "Beijing", "school": "Nanjing University", "married": false, "about": "I love Beijing Opera"}'输出:{ "_index" : "employee", index名。 "_type" : "dev", Type名。 "_id" : "1", 这条Document的ID。。 "_version" : 1, 版本号,每执行依次命令就加1。 "_shards" : { shard数目及状态。 "total" : 2, "successful" : 2, "failed" : 0 }, "created" : true true表示第一次创建。 }
9.查看/employee/dev/1下是否存在Document curl -i -XHEAD 'localhost:9200/employee/dev/1?pretty'
10.获取/employee/dev/1下的Document curl -XGET 'localhost:9200/employee/dev/1?pretty'
11.更新文档 curl -XPUT 'localhost:9200/employee/dev/1?pretty' -d '{ "firstname": "小江", "lastname": "雷", "age": 27, "on_board_date": "1995-02-02", "hometown": "南京", "school": "28所老年大学", "married": false, "about": "铁肩担大任,冲上山顶论英雄,联合起来办大事,做就做到最好,让创新成为习惯,共享才能共赢,创造幸福而有尊严的生活"}'
12.获取/employee/dev/1中的 name 和 age 字段,多个字段用“,”隔开 curl -XGET 'localhost:9200/employee/dev/1?_source=firstname,lastname,age&pretty'
13.获取source部分的数据 curl -XGET 'localhost:9200/employee/dev/1/_source?pretty'
14.新建一个document,会自动生成rowkey: curl -XPOST 'localhost:9200/employee/sales?pretty' -d '{ "firstname": "Lei", "lastname": "Li", "age": 28, "on_board_date": "2013-10-03", "hometown": "Hangzhou", "school": "Zhejiang University", "married": true, "about": "I appear in your English textbook."}'
15.查询一条记录; curl -XGET 'localhost:9200/employee/_search?pretty&q=lastname:"wang"'
16.设置副本数: curl -XPUT 'localhost:9200/employee/_settings?pretty' -d '{ "number_of_replicas": 2}'
16.设置刷新间隔(入库30秒后才能查询到数据,原本是入库一秒就可以查询到入库的数据,es要做很多合并的操作,会占用系统资源,降低入库速度) curl -XPUT 'localhost:9200/employee/_settings' -d ' { "index" :{ "refresh_interval" : "30s" } } '17.设置segment大小 curl -XPOST 'localhost:9200/employee/_optimize?max_num_segments=3&pretty'
18.设置批量插入的队列大小curl -XPUT 'localhost:9200/_cluster/settings' -d '{"persistent":{"indices.store.throttle.max_bytes_per_sec" : "100mb","threadpool.bulk.queue_size" : "10000"}}'
19.查看es集群nodes状态,是否挂掉 curl -XGET 'localhost:9200/_cat/nodes?pretty'
20.查看所有节点的统计数据 curl -XGET 'localhost:9200/_nodes/stats?pretty' curl -XGET 'localhost:9200/_nodes/gz230-110/stats?pretty' (查看指定节点的状态)
21.空检索 curl -XGET 'localhost:9200/_search?pretty'
22.指定条件检索 curl -XGET 'localhost:9200/employee/sales/_search' curl -XGET 'localhost:9200/employee/sales,dev/_search' curl -XGET 'localhost:9200/employee/dev/_search?pretty&q=lastname:Li' (uri检索)
23.请求体检索: curl -XPOST 'localhost:9200/employee/dev/_search?pretty' -d '{ "query" : { "match_phrase" : { "lastname" : "Li" } }}'24.指定条件URI检索 curl -XGET 'localhost:9200/employee/_search?q=Beijing&df=school'(默认查询字段为school) curl -XGET 'localhost:9200/employee/_search?q=school:(Beijing AND University)'(AND查询) curl -XGET 'localhost:9200/employee/_search?q=school:(Beijing OR University)'(OR查询) curl -XGET 'localhost:9200/employee/_search?q=*&from=1&size=10'(指定返回从第几条开始,几条结果) curl -XGET 'localhost:9200/default.test_people_es_1/_search?q=*&sort=id:asc&pretty' (排序) curl -XGET 'localhost:9200/employee/_search?q=(lastname:li) AND (school:beijing)'(查询条件AND)
curl -XGET 'localhost:9100/employee/_search?q=+school:nanjing+school:beijing' (+操作符)
curl -XGET 'localhost:9100/employee/_search?q=-school:university' (-操作符)
curl -XGET 'localhost:9200/employee/_search?q=school=(beijing AND university) OR (na AND university)' (括号的使用)
curl -XGET 'localhost:9200/employee/_search?q=??d*' (?匹配任意一个字符,*匹配任意个数的字符)
curl -XGET 'localhost:9200/employee/_search?q=on_board_date:(>2014-01-01 AND <2015-12-31)' (日期范围查询)
25.按照querybody检索: curl -XGET '172.20.230.110:9200/default.test_people_es/_search?pretty' -d '{ "query": { "bool" : { "must" : { "term":{ "sex": "女" } } } } }'
26.移动分片假设我们有两个节点:es_node_one和es_node_two,ElasticSearch在es_node_one节点上分配了ops索引的两个分片,我们现在希望将第二个分片移动到es_node_two节点上。可以如下操作实现:# curl -XPOST "http://ESnode:9200/_cluster/reroute' -d '{ "commands" : [ { "move" : { "index" : "ops", "shard" : 1, "from_node" : "es_node_one", "to_node" : "es_node_two" } }] }'27.分配分片我们还可以将一个未分配的分片分配到一个指定的节点上。假设ops索引上有一个编号为0的分片尚未分配,并且我们希望ElasticSearch将其分配到es_node_two上,可以运行如下命令操作:# curl -XPOST "http://ESnode:9200/_cluster/reroute' -d '{ "commands" : [ { "allocate" : { "index" : "ops", "shard" : 0, "node" : "es_node_two" } } ] }' 28.取消分配如果希望取消一个正在进行的分配过程,我们通过运行cancel命令来指定我们希望取消分配的索引、节点以及分片,如下所示:# curl -XPOST "http://ESnode:9200/_cluster/reroute" -d '{ "commands" : [ { "cancel" : { "index" : "ops", "shard" : 0, "node" : "es_node_one" } } ] }' 创建索引:# curl -XPOST "http://ESnode:9200/katoey"
分配索引在某一节点:# curl -XPUT "http://ESnode:9200/katoey/_settings" -d '{ "index.routing.allocation.include.zone": "zone_one,zone_two" }'# curl -XPUT "http://ESnode:9200/_cluster/settings" -d '{ "transient" : { "cluster.routing.allocation.include._ip" "10.0.1.112,10.0.1.114" } }'
设置每个节点上的分片为1: # curl -XPUT "http://ESnode:9200/ops/_settings" -d '{ "index.routing.allocation.total_shards_per_node" : 1 }' 29.测试分词,analyzer=ik :用于指定分词器名;上述的四个分词器(english,standard,ik,mmseg)都可以指定 curl -XPOST ‘localhost:9200/_analyze?analyzer=ik&&pretty’ -d '南京火车站' 二、知识点说明部分:1.边框为深色的分片是index的主分片,其他为主分片的副本;2.方框中的数字表示同一索引的不同分片,相同数字表示同一分片的不同副本;3.索引的主分片的数目,建表后不可改;4.transwarp Search的含有三个特殊的数据对象:Index,Type,Document,Field,它们与传统二维表的映射关系如下: Index(索引)-->Table(表) Document-->Row(行) Field(字段)-->Column(列) Type 是Index的逻辑上的分类,不映射为传统二维表中的数据对象。5.如果一个Index的 Replica 数大于或等于集群中节点数量,这个Index中将会有分片无法分配到节点上;6.如果您需要在 <QUERY_STRING> 中包含以下Transwarp Search保留字符,您需要使用 \ 进行转译:+ - = && || > < ! ( ) { } [ ] ^ " ~ * ? : \ /
