查看集群状态

curl http://10.0.1.123:9200/_cat/health?v

查看节点状态

 curl http://10.0.1.123:9200/_cat/nodes?v

查看索引状态

curl http://10.0.1.123:9200/_cat/indices?v

查看分片状态

curl http://10.0.1.123:9200/_cat/shards?v

删除指定的索引

curl -X DELETE http://10.0.1.123:9200/索引名字

批量删除指定节点索引

for i in   `curl -XGET 'http://10.0.1.123:9200/_cat/shards'|grep 10.0.1.123 |grep 221006| awk '{print $1}'`   ; do curl -XDELETE "http://10.0.1.123:9200/$i"; done

查看索引当前模板设置

http://10.0.1.123:9200/*/_settings?pretty

关闭索引写保护

curl -XPUT -H "Content-Type: application/json" http://10.0.1.123:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'
验证
curl -XPUT -H "Content-Type: application/json" http://10.0.1.123:9200/索引名称/_settings -d  '{"index": {"blocks": { "read_only_allow_delete": "false"}}}'
返回
{"acknowledged":true}

热数据分片标记为冷数据分片

curl -XPUT -H "Content-Type: application/json" http://10.12.73.2:9200/*-221101-*/_settings -d  '{"index.routing.allocation.require.box_type": "cold"}'

批量删除索引

 curl http://10.12.73.2:9200/_cat/indices       |grep 221005 |awk '{print $3}'  | xargs -n 1 -I {} curl -XDELETE http://10.12.73.2:9200/{}
