elasticsearch索引只读

由于磁盘的空间太小，被强制只读了
治病还是要治根

org.elasticsearch.xpack.monitoring.exporter.ExportException: ClusterBlockException[blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];]

解决

curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'

es查看和删除索引
查看索引

curl localhost:9200/_cat/indices?v

删除索引,通配符形式

curl -XDELETE localhost:9200/索引*

索引起别名

curl -XPUT localhost:9200/索引/_alias/别名

查看别名

curl -XPUT localhost:9200/_cat/aliases?v

单机状态下显示yellow
调整副本数

curl -XPUT 'http://localhost:9200/_settings' -H 'Content-Type: application/json' -d '
{
    "index" : {
        "number_of_replicas" : 0
    }
}'

Kibana控制台下这样执行:

PUT _settings
{
    "index" : {
        "number_of_replicas" : 0
    }
}
