How do I delete everything in Redis?

I want to delete all keys. I want everything wiped out and give me a blank database.

Is there a way to do this in Redis client?

With redis-cli:

• FLUSHDB – Deletes all keys from the connection's current database.
• FLUSHALL – Deletes all keys from all databases on current host.

For example, in your shell:

redis-cli flushall
