Redis disable commands, dangerous commands, and circumvention methods _redis

The Flushall flushdb command clears the data and never fails, which is dangerous for online clusters.

The KEYS * command, when used when the data scale is large, can seriously affect redis performance and is very dangerous.

What if these risks are fundamentally circumvented?

Redis provides a very simple and efficient way to set the disable commands directly in the configuration file. The settings are very simple, as follows

Copy Code code as follows:

Rename-command Flushall ""
Rename-command flushdb ""
Rename-command KEYS ""

It is important to note that Rename-command naming cannot be directly effective on an online cluster. If you need to use Rename-command, you must restart the cluster.

So it is recommended that the configuration be configured in the first place.
