How to empty a redis database?
提问by Luc
I've been playing with redis (and add some fun with it) during the last fews days and I'd like to know if there is a way to empty the db (remove the sets, the existing key....) easily.
During my tests, I created several sets with a lot of members, even created sets that I do not remember the name (how can I list those guys though ?).
Any idea about how to get rid of all of them ?
在过去的几天里，我一直在玩 redis（并增加一些乐趣），我想知道是否有办法轻松清空数据库（删除集合、现有密钥......） .
在我的测试中，我创建了几个包含很多成员的集合，甚至创建了一些我不记得名字的集合（但是我怎么能列出这些人？）。
关于如何摆脱所有这些的任何想法？

open your Redis cli and There two possible option that you could use:
打开您的 Redis cli，您可以使用两种可能的选项：
FLUSHDB - Delete all the keys of the currently selected DB. FLUSHALL - Delete all the keys of all the existing databases, not just the currently selected one.
FLUSHDB - 删除当前选定数据库的所有键。FLUSHALL - 删除所有现有数据库的所有键，而不仅仅是当前选择的键。
