0x00 _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
1. 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/
0x01 _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、显示集群系统信息，包括CPU JVM等等
curl -XGET localhost:9200/_cluster/stats?pretty=true
3、 集群的详细信息。包括节点、分片等。
curl -XGET localhost:9200/_cluster/state?pretty=true
3、获取集群堆积的任务
curl -XGET localhost:9200/_cluster/pending_tasks?pretty=true
4、修改集群配置
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
5、对shard的手动控制
curl -XPOST ‘localhost:9200/_cluster/reroute’ -d ‘xxxxxx’
对shard的手动控制，参考http://zhaoyanblog.com/archives/687.html
6、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’
7、关闭主节点
curl -XPOST ‘http://localhost:9200/_cluster/nodes/_master/_shutdown’
8、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
0x02 _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
0x03 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 }
