  • To check the version of Redis that is installed, use the command below.
redis-server -v
  • Do a ping test to verify the Redis server is working.

Sample output> ping
PONG> exit

Set Redis password on Debian 11

  • Open the Redis configuration file using the command below.
sudo nano /etc/redis/redis.conf

Next, search for requirepass foobared and uncomment it by removing the # symbol then replace foobared with your preferred password.

# IMPORTANT NOTE: starting with Redis 6 "requirepass" is just a compatibility
# layer on top of the new ACL system. The option effect will be just setting
# the password for the default user. Clients will still authenticate using
# AUTH  as usually, or more explicitly with AUTH default 
# if they follow the new protocol: both will work.

requirepass YourStrongPassword

# Command renaming (DEPRECATED).
# ------------------------------------------------------------------------
# WARNING: avoid using this option if possible. Instead use ACLs to remove
# commands from the default user, and put them only in some admin user you
# create for administrative purposes.
# ------------------------------------------------------------------------
  • Restart Redis to apply changes using the following command.
sudo systemctl restart redis
  • Let’s do the ping test again, authentication will be required.

Sample output> ping
(error) NOAUTH Authentication required.> auth YourStrongPassword
OK> exit
  • That concludes our guide on how to install Redis on Debian 11.
