💡 Hint

Common Mistakes

Using a port number that is not standard for Redis.

Leaving the port number blank or commented out.

The default Redis port is 6379. Setting port 6379 configures Redis to listen on this port.

💡 Hint

Common Mistakes

Using too short or too long intervals that do not match the requirement.

Confusing the order of parameters in the save directive.

The save 900 1 directive tells Redis to save the DB if at least 1 key changed in 900 seconds.

💡 Hint

Common Mistakes

Using 'true' or 'false' instead of 'yes' or 'no'.

Leaving protected mode enabled when it should be disabled.

To disable protected mode, set protected-mode no. Using 'yes' or boolean strings causes errors.

💡 Hint

Common Mistakes

Using different passwords in the two places.

Leaving the password commented out.

The requirepass directive sets the password Redis requires for clients. Both blanks must be the same password.

Fill all three blanks to configure Redis to bind only to localhost, disable protected mode, and set maxmemory to 256mb.

Redis

bind [1]
protected-mode [2]
maxmemory [3]

Drag options to blanks, or click blank then click option'

A127.0.0.1

Bno

C256mb

D0.0.0.0

💡 Hint

Common Mistakes

Binding to 0.0.0.0 exposes Redis to all interfaces.

Using 'yes' instead of 'no' for protected mode.

Setting maxmemory without units.

Binding to 127.0.0.1 restricts Redis to localhost. Disabling protected mode requires 'no'. Setting maxmemory to '256mb' limits memory usage.
