elasticsearch交互式命令查询（三）

elasticsearch交互式命令查询（三）

elasticsearch交互方式

1.elasticsearch交互方式

curl命令： ​ 最繁琐 ​ 最复杂 ​ 最容易出错 ​ 不需要安装任何软件，值需要有curl命令 es-head插件 ​ 查看数据方便 ​ 操作相对容易 ​ 需要node环境 kibana ​ 查看数据以及报表格式丰富 ​ 操作很简单 ​ 需要java环境和安装配置kibana

1.1.查看es基本信息

[root@elastic ~]# curl 192.168.81.210:9200/_cat =^.^= /_cat/allocation /_cat/shards /_cat/shards/{index} /_cat/master /_cat/nodes /_cat/tasks /_cat/indices /_cat/indices/{index} /_cat/segments /_cat/segments/{index} /_cat/count /_cat/count/{index} /_cat/recovery /_cat/recovery/{index} /_cat/health /_cat/pending_tasks /_cat/aliases /_cat/aliases/{alias} /_cat/thread_pool /_cat/thread_pool/{thread_pools} /_cat/plugins /_cat/fielddata /_cat/fielddata/{fields} /_cat/nodeattrs /_cat/repositories /_cat/snapshots/{repository} /_cat/templates

1.2.查看es分片信息

下面的输出可以看出是分了5个片，一个主分片一个副本分片

[root@elastic ~]# curl 192.168.81.210:9200/_cat/shards testinfo 2 p STARTED 0 261b 192.168.81.240 node-1 testinfo 2 r UNASSIGNED testinfo 1 p STARTED 0 261b 192.168.81.240 node-1 testinfo 1 r UNASSIGNED testinfo 3 p STARTED 0 261b 192.168.81.240 node-1 testinfo 3 r UNASSIGNED testinfo 4 p STARTED 0 261b 192.168.81.240 node-1 testinfo 4 r UNASSIGNED testinfo 0 p STARTED 0 261b 192.168.81.240 node-1 testinfo 0 r UNASSIGNED

1.3.使用curl命令创建索引

开启127.0.0.1访问地址[root@elastic ~]# vim /etc/elasticsearch/elasticsearch.ymlnetwork.host: 192.168.81.240,127.0.0.1[root@elastic ~]# systemctl restart elasticsearch 注意创建索引时，curl命令的参数一定要保持顺序 命令格式：curl -XPUT 'es地址:prot/索引名?pretty'

1.创建索引 [root@elastic ~]# curl -XPUT '192.168.81.210:9200/testinfo?pretty' { "acknowledged" : true, "shards_acknowledged" : true, "index" : "testinfo" } 2.查看索引 [root@elastic ~]# curl 192.168.81.210:9200/_cat/indices yellow open testinfo iucttBn4SsWpFQA24V8pYg 5 1 0 0 1.2kb 1.2kb

1.4.使用curl向索引插入数据

命令格式： ​ curl -XPUT 'es地址:port/索引/类型/id?pretty' -H 'COntent-Type: application/json' -d'{值}'

[root@elastic ~]# curl -XPUT '192.168.81.210:9200/testinfo/user/1?pretty' -H 'COntent-Type: application/json' -d' { "first_name" : "jiang", "last_name" : "xiaolong", "age" : 99, "about" : "I like linux", "interests": [ "sports", "music" ] } ' { "_index" : "testinfo", "_type" : "user", "_id" : "1", "_version" : 1, "result" : "created", "_shards" : { "total" : 2, "successful" : 1, "failed" : 0 }, "_seq_no" : 0, "_primary_term" : 1 } 在创建一个id为2的文本 [root@elastic ~]# curl -XPUT '192.168.81.210:9200/testinfo/user/2?pretty' -H 'COntent-Type: application/json' -d' { "first_name" : "jiang", "last_name" : "xl", "age" : 77, "about" : "I like linux", "interests": [ "sports", "music" ] }'

刚刚创建的两个数据都是指定id的我们来写一个不指定id的 格式： ​ curl -XPOST 'es地址:port/索引/类型?pretty/' -H 'COntent-Type: application/json' -d'{值}' 或 ​ curl -XPOST 'es地址:port/索引/类型/' -H 'COntent-Type: application/json' -d'{值}' ​ 这个输出是一行不如第一种

[root@elaticsearch ~]# curl -X POST '192.168.81.210:9200/testinfo/user?pretty' -H 'COntent-Type: application/json' -d' { "first_name" : "jiang", "last_name" : "xl", "age" : 77, "about" : "I like linux", "interests": [ "sports", "music" ] }' { "_index" : "testinfo", "_type" : "user", "_id" : "p-58inYBlNQwpkFxBxiY", #随机生成的 "_version" : 1, "result" : "created", "_shards" : { "total" : 2, "successful" : 1, "failed" : 0 }, "_seq_no" : 1, "_primary_term" : 1 } 再创建一个 [root@elastic ~]# curl -XPOST '192.168.81.210:9200/testinfo/user?pretty' -H 'COntent-Type: application/json' -d' { "first_name" : "zhang", "last_name" : "jia", "age" : 77, "about" : "I like linux", "interests": [ "sports", "music" ] }'
