Elasticsearch之删除索引

curl -XDELETE -u elastic:changeme http://localhost:9200/acc-apply-2018.08.09
{"acknowledged":true}

curl -XDELETE -u elastic:changeme http://localhost:9200/acc-apply-2018.08.09,acc-apply-2018.08.10

curl -XDELETE -u elastic:changeme http://localhost:9200/acc-apply-*
{"acknowledged":true}

curl -XDELETE http://localhost:9200/_all
或 curl -XDELETE http://localhost:9200/*
    _all ,* 通配所有的索引
    通常不建议使用通配符，误删了后果就很严重了，所有的index都被删除了
    禁止通配符为了安全起见，可以在elasticsearch.yml配置文件中设置禁用_all和*通配符
    action.destructive_requires_name = true
    这样就不能使用_all和*了

curl -u elastic:changeme 'localhost:9200/_cat/indices?v'

30 2 * * * /usr/bin/curl -XDELETE -u elastic:changeme http://localhost:9200/*-$(date -d '-3days' +'%Y.%m.%d') >/dev/null 2>&1

#!/bin/bash
time=$(date -d '-3days' +'%Y.%m.%d')
curl -XDELETE -u elastic:changeme http://localhost:9200/*-${time}
