Redis Disable Flushall,flushdb,keys command

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

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

Rename-command Keys ""

Rename-command naming cannot take effect directly on the online cluster. If you need to use Rename-command, you must restart the cluster.

Disabling these 3 commands is to avoid large risks.

The 1.FLUSHALL,FLUSHDB command empties the data and never fails, which is dangerous for online clusters.

The 2.keys * command, when used with large data sizes, can severely affect Redis performance and is also very dangerous.
