elasticsearch基本接口使用

一、查看当前es上的所有索引

curl -XGET "http://127.0.0.1:9200/_cat/indices" 　　 # 查看索引缩略信息

curl -XGET "http://127.0.0.1:9200/_cat/indices?v" 　　# 查看索引详细信息

二、查看elasticsearch集群状态

curl -sXGET "http://127.0.0.1:9200/_cluster/health?pretty"

{
  "cluster_name" : "elasticone",
  "status" : "yellow",
  "timed_out" : false,
  "number_of_nodes" : 1,
  "number_of_data_nodes" : 1,
  "active_primary_shards" : 541,
  "active_shards" : 541,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 541,
  "delayed_unassigned_shards" : 0,
  "number_of_pending_tasks" : 0,
  "number_of_in_flight_fetch" : 0,
  "task_max_waiting_in_queue_millis" : 0,
  "active_shards_percent_as_number" : 50.0
}

三、查看集群节点信息

curl -XGET "http://127.0.0.1:9200/_cat/nodes?v"

四、查看节点进程信息

curl -XGET "http://127.0.0.1:9200/_nodes/process?pretty"

五、查看索引统计信息

curl -XGET "http://127.0.0.1:9200/_stats?pretty"

六、查看指定索引统计信息

curl -XGET "http://127.0.0.1:9200/索引名/_stats?pretty"

curl -XGET "http://127.0.0.1:9200/logstash-2018.10.21/_stats?pretty"

七、查看热点线程

curl -XGET "http://127.0.0.1:9200/_nodes/hot_threads?pretty"

八、查看指定索引信息

curl -XGET "http://127.0.0.1:9200/索引名/_mapping?pretty"

curl -XGET "http://127.0.0.1:9200/logstash-2018.10.21/_mapping?pretty"

九、查看所有节点jvm信息

curl -XGET "http://127.0.0.1:9200/_nodes/stats/jvm?pretty"

十、查看指定节点jvm信息

curl -XGET "http://127.0.0.1:9200/_nodes/节点名/stats/jvm?pretty"

curl -XGET "http://127.0.0.1:9200/_nodes/searchnode-01/stats/jvm?pretty"

十一、删除全部索引

curl -XDELETE "http://127.0.0.1:9200/*?pretty"

十二、删除指定索引

curl -XDELETE "http://127.0.0.1:9200/索引名?pretty"

curl -XDELETE "http://127.0.0.1:9200/logstash-2018.10.19?pretty"

 curl -XDELETE "http://127.0.0.1:9200/logstash-2018.10.19?pretty"
{
  "acknowledged" : true
}

# 删除历史索引思路 

# step1  取出要删除的索引名 
curl -sXGET "http://127.0.0.1:9200/_cat/indices"|awk '{print $3}'|grep 2018.10    # 2018.10月的所有索引

# step2  使用for循环调用接口删除之 
for i in `curl -sXGET "http://127.0.0.1:9200/_cat/indices"|awk '{print $3}'|grep 2018.10`;do curl -XDELETE "http://127.0.0.1:9200/$i?pretty";done

十三、查看线程池配置

curl -XGET "http://127.0.0.1:9200/_nodes/thread_pool/"
