Elasticsearch终端命令行用法大全

1、平衡集群分片

curl -sXPUT "http://localhost:9200/*2019.04.20/_settings" -d '{"index.routing.allocation.total_shards_per_node":3}'

2、查询集群线程池

curl -sXGET "http://localhost:9200/_cat/thread_pool" | awk '{if($3>0)print $0}'

3、集群执行segment合并

ES5.X: curl -X POST "localhost:9200/_all/_forcemerge?max_num_segments=1"
ES2.X: curl -X POST "localhost:9200/situation-event/_optimize?max_num_segments=1"

4、查看segment合并效果

curl "http://localhost:9200/_cat/indices?h=health,status,index,pri,rep,docs.count,segments.count,uuid,docs.deleted"| awk '{if($4*(1+$5) != $7){print $0}}' | wc -l

5、设置添加删除节点或负载均衡时并发恢复线程的个数

curl -sXPUT "http://localhost:9200/_cluster/settings" -d '{"transient":{"cluster.routing.allocation.node_concurrent_recoveries":"20"}}'

6、查询某个索引的分配情况

curl -XGET localhost:9200/_cluster/allocation/explain?pretty -d '{"index":"skyeye-udpflow-2019.04.12","shard":1,"primary":true}'

7、查看集群健康状态

curl http://127.0.0.1:9200/_cluster/health?pretty

8、集群状态信息

curl -XGET 'http://localhost:9200/_cluster/stats?human&pretty'

9、节点监控

curl http://127.0.0.1:9200/_nodes/stats?pretty 
10、索引监控
curl http://127.0.0.1:9200/_stats?pretty

10、打开/关闭索引

curl -XPOST http://127.0.0.1:9200/my_index/_close
curl -XPOST http://127.0.0.1:9200/my_index/_open

11、查看磁盘占用情况

curl 127.0.0.1:9200/_cat/allocation?v

13、查看集群恢复状态

curl -XGET http://localhost:9200/_recovery?pretty=true
curl -XGET localhost:9200/_cat/recovery | grep -v done | wc -l

14、查看fielddata占用情况

curl -XGET localhost:9200/_cat/fielddata?v

15、查询访问node和shard

curl -XPOST localhost:9200/[索引]/_search_shards -d '[查询语句]'
