Curator 是一个elasticsearch集群管理工具,在日常集群管理方面的一个利器,掌握此神器,es集群日常管理将轻松+愉快。
如下:
创建索引
删除索引
关闭索引
删除快照
从快照还原
添加或移除索引
打开已经关闭的索引
更改分片路由配置
强制合并索引
更改索引每个分片的副本数量
为索引创建快照
reindices 、remote reindices
rollover indices(当某个别名指向的实际索引过大的时候,自动将别名指向下一个实际索引)
等等。。。。。

可以根据指定条件匹配,然后指定相应的动作。
curator_cli --host 172.20.11.32 --port 9200 close --filter_list '[{"filtertype":"age","source":"creation_date","direction":"older","unit":"days","unit_count":30},{"filtertype":"pattern","kind":"prefix","value":"ptlog-"}]'
查看索引信息

发现符合条件的索引状态都调整为 close !
curator_cli --host 172.20.11.32 --port 9200 delete_indices --filter_list '[{"filtertype":"age","source":"creation_date","direction":"older","unit":"days","unit_count":30},{"filtertype":"pattern","kind":"prefix","value":"ptlog-"}]'

发现所有 close 状态的索引都被删除了,生产环境推荐这样操作,先关闭一段时间观察,然后再删除数据,毕竟恢复数据比较麻烦。
