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
}
}
'
