一、查看内外网访问地址
在 集群列表页，单击集群 ID/名称进入详情页，单击访问控制。
·对于内网地址，在基础配置中可直接查看。
·对于外网地址，出于安全考虑默认是关闭的。对于已开启 ES 集群用户登录认证 的集群，支持开启公网地址。开启公网访问可能会为集群引入安全风险，同时也将允许通过 API 直接访问、操作甚至删除在 ElasticSearch 集群中的数据，请谨慎开启。
二、测试访问
可通过 curl 的方式测试访问集群，不支持通过 ping 的方式测试连通性。
三、测试服务是否可访问
注意：对于已开启 ES 集群用户登录认证 的集群，登录时需要用户名和密码认证，具体规则为curl action -u user:password host …，需要将 user、password 替换为自己实际的用户名和密码，将 host 替换为自己的 IP。
下面将以内网地址访问来演示各访问操作。输入命令：
curl -XGET http://10.0.17.2:9200若开启了ES集群用户登录认证，请注意输入用户名密码curl -XGET -u user:password http://10.0.17.2:9200
返回如下，表示集群访问正常，具体参数的值会根据集群的版本有所不同：
{"name": "15589826570000*****","cluster_name": "es-******","cluster_uuid": "NGIm1M_zRw-L3o_gH****","version": { "number": "6.4.3", "build_flavor": "default", "build_type": "zip", "build_hash": "fe40335", "build_date": "2019-05-17T14:22:47.286024Z", "build_snapshot": false, "lucene_version": "7.4.0", "minimum_wire_compatibility_version": "5.6.0", "minimum_index_compatibility_version": "5.0.0"},"tagline": "You Know, for Search"}
四、创建单个文档
·若集群未开启用户登录认证， 输入命令行：
curl -XPUT http://10.0.0.2:9200/china/_doc/beijing -H 'Content-Type: application/json' -d'{"name":"北京市","province":"北京市","lat":39.9031324643,"lon":116.4010433787,"x":6763,"level.range":4,"level.level":1,"level.name":"一线城市","y":6381,"cityNo":1}'
·若集群已开启用户登录认证，需要将下文中的 user、password 替换为自己集群实际的用户名和密码。输入命令行：
curl -XPUT -u user:password http://10.0.0.2:9200/china/_doc/beijing -H 'Content-Type: application/json' -d'{"name":"北京市","province":"北京市","lat":39.9031324643,"lon":116.4010433787,"x":6763,"level.range":4,"level.level":1,"level.name":"一线城市","y":6381,"cityNo":1}'
响应如下：
{"_index":"china","_type":"_doc","_id":"beijing","_version":1,"result":"created","_shards":{ "total":2, "successful":1, "failed":0},"created":true}
五、创建多个文档
输入命令行：
curl -XPOST http://10.0.0.2:9200/_bulk -H 'Content-Type: application/json' -d'{ "index" : { "_index": "china", "_type" : "_doc", "_id" : "beijing" } }{"name":"北京市","province":"北京市","lat":39.9031324643,"lon":116.4010433787,"x":6763,"level.range":4,"level.level":1,"level.name":"一线城市","y":6381,"cityNo":1}{ "index" : { "_index": "china", "_type" : "_doc", "_id" : "shanghai" } }{"name":"上海市","province":"上海市","lat":31.2319526784,"lon":121.469443249,"x":7779,"level.range":4,"level.level":1,"level.name":"一线城市","y":4409,"cityNo":2}{ "index" : { "_index": "china", "_type" : "_doc", "_id" : "guangzhou" } }{"name":"广州市","province":"广东省越秀区吉祥路79号","lat":23.1317146641,"lon":113.2595185241,"x":6173,"level.range":4,"level.level":1,"level.name":"一线城市","y":2560,"cityNo":3}{ "index" : { "_index": "china", "_type" : "_doc", "_id" : "shenzhen" } }{"name":"深圳市","province":"广东省福田区新园路37号","lat":22.5455465546,"lon":114.0527779134,"x":6336,"level.range":4,"level.level":1,"level.name":"一线城市","y":2429,"cityNo":4}{ "index" : { "_index": "china", "_type" : "_doc", "_id" : "chengdu" } }{"name":"成都市","province":"四川省锦江区红星路4段-88号-附1号","lat":30.6522796787,"lon":104.0725574128,"x":4387,"level.level":2,"level.range":19,"level.name":"新一线城市","y":4304,"cityNo":5}{ "index" : { "_index": "china", "_type" : "_doc", "_id" : "hangzhou" } }{"name":"杭州市","province":"浙江省拱墅区环城北路316号","lat":30.2753694112,"lon":120.1509063337,"x":7530,"level.level":2,"level.range":19,"level.name":"新一线城市","y":4182,"cityNo":6}'
响应如下：
"took":9,"errors":false,"items":[{"index":{"_index":"china","_type":"_doc","_id":"beijing","_version":4,"result":"updated","_shards":{"total":2,"successful":2,"failed":0},"created":false,"status":200}},{"index":{"_index":"china","_type":"_doc","_id":"shanghai","_version":2,"result":"updated","_shards":{"total":2,"successful":2,"failed":0},"created":false,"status":200}},{"index":{"_index":"china","_type":"_doc","_id":"guangzhou","_version":1,"result":"created","_shards":{"total":2,"successful":2,"failed":0},"created":true,"status":201}},{"index":{"_index":"china","_type":"_doc","_id":"shenzhen","_version":1,"result":"created","_shards":{"total":2,"successful":2,"failed":0},"created":true,"status":201}},{"index":{"_index":"china","_type":"_doc","_id":"chengdu","_version":2,"result":"updated","_shards":{"total":2,"successful":2,"failed":0},"created":false,"status":200}},{"index":{"_index":"china","_type":"_doc","_id":"hangzhou","_version":2,"result":"updated","_shards":{"total":2,"successful":2,"failed":0},"created":false,"status":200}}]
六、更新文档
重复上文创建单个文档的输入代码，即可更新指定 ID beijing的文档。 响应如下：
{"_index":"china","_type":"_doc","_id":"beijing","_version":2,"result":"updated","_shards":{"total":2,"successful":2,"failed":0},"created":false}
七、查询指定 ID
输入命令行：
curl -XGET 'http://10.0.0.2:9200/china/_doc/beijing?pretty' -H 'Content-Type: application/json'
响应如下：
{"_index" : "china","_type" : "_doc","_id" : "beijing","_version" : 4,"found" : true,"_source" : { "name" : "北京市", "province" : "北京市", "lat" : 39.9031324643, "lon" : 116.4010433787, "x" : 6763, "level.range" : 4, "level.level" : 1, "level.name" : "一线城市", "y" : 6381, "cityNo" : 1}}
八、查询某个索引
输入命令行：
curl -XGET 'http://10.0.0.2:9200/china/_search?pretty' -H 'Content-Type: application/json'
响应如下：
{"took" : 0,"timed_out" : false,"_shards" : { "total" : 5, "successful" : 5, "skipped" : 0, "failed" : 0},"hits" : { "total" : 6, "max_score" : 1.0, "hits" : [ { "_index" : "china", "_type" : "_doc", "_id" : "guangzhou", "_score" : 1.0, "_source" : { "name" : "广州市", "province" : "广东省越秀区吉祥路79号", "lat" : 23.1317146641, "lon" : 113.2595185241, "x" : 6173, "level.range" : 4, "level.level" : 1, "level.name" : "一线城市", "y" : 2560, "cityNo" : 3 } }] }, ……}
九、复杂查询
模拟 SQL：
select * from china where level.level=2/* 如下就是内网curl 的方式来实现上面的sql查询 */curl -XGET http://10.0.0.2:9200/china/_search?pretty -H 'Content-Type: application/json' -d'{ "query" : { "constant_score" : { "filter" : { "term" : { "level.level" : 2 } } } }}'
响应如下：
{"took" : 2,"timed_out" : false,"_shards" : { "total" : 5, "successful" : 5, "skipped" : 0, "failed" : 0},"hits" : { "total" : 2, "max_score" : 1.0, "hits" : [ { "_index" : "china", "_type" : "_doc", "_id" : "chengdu", "_score" : 1.0, "_source" : { "name" : "成都市", "province" : "四川省锦江区红星路4段-88号-附1号", "lat" : 30.6522796787, "lon" : 104.0725574128, "x" : 4387, "level.level" : 2, "level.range" : 19, "level.name" : "新一线城市", "y" : 4304, "cityNo" : 5 } }, { "_index" : "china", "_type" : "_doc", "_id" : "hangzhou", "_score" : 1.0, "_source" : { "name" : "杭州市", "province" : "浙江省拱墅区环城北路316号", "lat" : 30.2753694112, "lon" : 120.1509063337, "x" : 7530, "level.level" : 2, "level.range" : 19, "level.name" : "新一线城市", "y" : 4182, "cityNo" : 6 } } ]}}
十、聚合查询
模拟 SQL：
select level.level, count(1) from city group by level.level/* 如下就是内网curl 的方式来实现上面的sql查询 */curl -XGET http://10.0.0.2:9200/china/_search?pretty -H 'Content-Type: application/json' -d'{ "size" : 0, "aggs" : { "city_level" : { "terms" : { "field" : "level.level" } } }}'
响应如下：
{"took" : 10,"timed_out" : false,"_shards" : { "total" : 5, "successful" : 5, "skipped" : 0, "failed" : 0},"hits" : { "total" : 7, "max_score" : 0.0, "hits" : [ ]},"aggregations" : { "city_level" : { "doc_count_error_upper_bound" : 0, "sum_other_doc_count" : 0, "buckets" : [ { "key" : 1, "doc_count" : 4 }, { "key" : 2, "doc_count" : 3 } ] }}}
十一、删除单个文档
输入命令行：
curl -XDELETE 'http://10.0.0.2:9200/china/_doc/beijing?pretty' -H 'Content-Type: application/json'
响应如下：
{"found" : true,"_index" : "china","_type" : "_doc","_id" : "beijing","_version" : 5,"result" : "deleted","_shards" : { "total" : 2, "successful" : 2, "failed" : 0}}
十二、删除类型
curl -XDELETE 'http://10.0.0.2:9200/china/_doc?pretty' -H 'Content-Type: application/json'
十三、删除索引
curl -XDELETE 'http://10.0.0.2:9200/china?pretty' -H 'Content-Type: application'
