ES 查看、删除索引命令

1、获取cat命令列表：

curl –X GET 127.0.0.1:9200/_cat/

2、带用户名密码查看索引信息

curl –X GET -u username:password  'http://192.168.90.161:9200/_cat/'

3、查看索引信息及空间占用：

​
curl -XGET 127.0.0.1:9200/_cat/indices?v
 
​

4、清理指定索引空间

curl -X POST "127.0.0.1:9200/索引名/_delete_by_query" -H 'Content-Type: application/json' -d'
 
 {
 
 "query": {
 
 "match_all": {
 
 }
 
 }
 
 }
 
 '

5、删除索引

curl  -X DELETE "http://127.0.0.1:9200/索引名"

6、删除30天前的索引记录

curl -X POST "127.0.0.1:9200/索引名/_delete_by_query" -H 'Content-Type: application/json' -d'
 
{
 
    "query": {
 
        "range": {
 
            "@timestamp": {
 
                "lt": "now-30d",
 
                "format": "epoch_millis"
 
            }
 
        }
 
    }
 
}

7、crontab 定时清理30天前数据

0 1 * * * /usr/bin/curl -H'Content-Type:application/json' -d'{"query":{"range":{"@timestamp":{"lt":"now-30d","format":"epoch_millis"}}}}' -XPOST "http://127.0.0.1:9200/*-*/_delete_by_query?pretty" > /tmp/elk_clean.txt

8、修改带密码的索引副本数量

curl -u "elastic" -X PUT "192.168.1.55:9200/*/_settings" -H 'Content-Type: application/json' -d'
 
{
 
"index" : {
 
"number_of_replicas" : 2
 
}
 
}
 
'
