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 url
    Prometheus analysis-mmseg   NA      j
    Prometheus analysis-pinyin  NA      j
    Prometheus analysis-ik      NA      j
    Prometheus analysis-ik      NA      j
    Prometheus analysis-smartcn 2.1.0   j
    Prometheus segmentspy       NA      s    /_plugin/segmentspy/
    Prometheus head             NA      s    /_plugin/head/
    Prometheus bigdesk          NA      s    /_plugin/bigdesk/
    Xandu      analysis-ik      NA      j
    Xandu      analysis-pinyin  NA      j
    Xandu      analysis-mmseg   NA      j
    Xandu      analysis-smartcn 2.1.0   j
    Xandu      head             NA      s    /_plugin/head/
    Xandu      bigdesk          NA      s    /_plugin/bigdesk/
    Onyxx      analysis-ik      NA      j
    Onyxx      analysis-mmseg   NA      j
    Onyxx      analysis-smartcn 2.1.0   j
    Onyxx      analysis-pinyin  NA      j
    Onyxx      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
    }
