ES01--CURL认知

第一：_cat系列
_cat系列提供了一系列查询elasticsearch集群状态的接口。你可以通过执行
curl -XGET localhost:9200/_cat
获取所有_cat系列的操作
=^.^=
/_cat/allocation
/_cat/shards
/_cat/shards/{index}
/_cat/master
/_cat/nodes
/_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/plugins
/_cat/fielddata
/_cat/fielddata/{fields}
你也可以后面加一个v，让输出内容表格显示表头，举例

name       component        version type urlPrometheus analysis-mmseg   NA      jPrometheus analysis-pinyin  NA      jPrometheus analysis-ik      NA      jPrometheus analysis-ik      NA      jPrometheus analysis-smartcn 2.1.0   jPrometheus segmentspy       NA      s    /_plugin/segmentspy/Prometheus head             NA      s    /_plugin/head/Prometheus bigdesk          NA      s    /_plugin/bigdesk/Xandu      analysis-ik      NA      jXandu      analysis-pinyin  NA      jXandu      analysis-mmseg   NA      jXandu      analysis-smartcn 2.1.0   jXandu      head             NA      s    /_plugin/head/Xandu      bigdesk          NA      s    /_plugin/bigdesk/Onyxx      analysis-ik      NA      jOnyxx      analysis-mmseg   NA      jOnyxx      analysis-smartcn 2.1.0   jOnyxx      analysis-pinyin  NA      jOnyxx      head             NA      s    /_plugin/head/Onyxx      bigdesk          NA      s    /_plugin/bigdesk/

第二：_cluster系列
1、查询设置集群状态
curl -XGET localhost:9200/_cluster/health?pretty=true
pretty=true表示格式化输出
level=indices 表示显示索引状态
level=shards 表示显示分片信息
2、curl -XGET localhost:9200/_cluster/stats?pretty=true
显示集群系统信息，包括CPU JVM等等
3、curl -XGET localhost:9200/_cluster/state?pretty=true
集群的详细信息。包括节点、分片等。
3、curl -XGET localhost:9200/_cluster/pending_tasks?pretty=true
获取集群堆积的任务
3、修改集群配置
举例：

curl -XPUT localhost:9200/_cluster/settings -d '{    "persistent" : {        "discovery.zen.minimum_master_nodes" : 2    }}'

transient 表示临时的，persistent表示永久的
4、curl -XPOST ‘localhost:9200/_cluster/reroute’ -d ‘xxxxxx’
对shard的手动控制，参考http://zhaoyanblog.com/archives/687.html
5、关闭节点
关闭指定192.168.1.1节点
curl -XPOST ‘http://192.168.1.1:9200/_cluster/nodes/_local/_shutdown’
curl -XPOST ‘http://localhost:9200/_cluster/nodes/192.168.1.1/_shutdown’
关闭主节点
curl -XPOST ‘http://localhost:9200/_cluster/nodes/_master/_shutdown’
关闭整个集群
$ curl -XPOST ‘http://localhost:9200/_shutdown?delay=10s’
$ curl -XPOST ‘http://localhost:9200/_cluster/nodes/_shutdown’
$ curl -XPOST ‘http://localhost:9200/_cluster/nodes/_all/_shutdown’
delay=10s表示延迟10秒关闭

第三：_nodes系列
1、查询节点的状态
curl -XGET ‘http://localhost:9200/_nodes/stats?pretty=true’
curl -XGET ‘http://localhost:9200/_nodes/192.168.1.2/stats?pretty=true’
curl -XGET ‘http://localhost:9200/_nodes/process’
curl -XGET ‘http://localhost:9200/_nodes/_all/process’
curl -XGET ‘http://localhost:9200/_nodes/192.168.1.2,192.168.1.3/jvm,process’
curl -XGET ‘http://localhost:9200/_nodes/192.168.1.2,192.168.1.3/info/jvm,process’
curl -XGET ‘http://localhost:9200/_nodes/192.168.1.2,192.168.1.3/_all
curl -XGET ‘http://localhost:9200/_nodes/hot_threads

第四：索引操作
1、获取索引
curl -XGET ‘http://localhost:9200/{index}/{type}/{id}’
2、索引数据
curl -XPOST ‘http://localhost:9200/{index}/{type}/{id}’ -d'{“a”:”avalue”,”b”:”bvalue”}’
3、删除索引
curl -XDELETE ‘http://localhost:9200/{index}/{type}/{id}’
4、设置mapping

curl -XPUT http://localhost:9200/{index}/{type}/_mapping -d '{  "{type}" : {"properties" : {  "date" : {"type" : "long"  },  "name" : {"type" : "string","index" : "not_analyzed"  },  "status" : {"type" : "integer"  },  "type" : {"type" : "integer"  }}  }}'

5、获取mapping
curl -XGET http://localhost:9200/{index}/{type}/_mapping
6、搜索

curl -XGET 'http://localhost:9200/{index}/{type}/_search' -d '{    "query" : {        "term" : { "user" : "kimchy" } //查所有 "match_all": {}    },"sort" : [{ "age" : {"order" : "asc"}},{ "name" : "desc" } ],"from":0,"size":100}curl -XGET 'http://localhost:9200/{index}/{type}/_search' -d '{    "filter": {"and":{"filters":[{"term":{"age":"123"}},{"term":{"name":"张三"}}]},"sort" : [{ "age" : {"order" : "asc"}},{ "name" : "desc" } ],"from":0,"size":100}
