Redis disable commands, dangerous commands, and circumvention methods

The Flushall flushdb command empties data and never fails, and is very dangerous for online clusters.

The KEYS * command, when used with large data sizes, can severely affect Redis performance and are also very dangerous.

What if these risks are fundamentally circumvented.

Redis provides a very simple and efficient way to set up disabling these commands directly in the configuration file. The settings are very simple, as follows
The code is as follows:
Rename-command Flushall ""
Rename-command flushdb ""
Rename-command KEYS ""

It is important to note that the Rename-command name cannot be directly applied to the online cluster. If you need to use Rename-command, you must restart the cluster.

Therefore, it is recommended that the configuration be configured at the outset.
