  • Next, let’s perform a ping test to confirm Redis is working.

Sample output> ping
PONG> exit

Set Redis password on Rocky Linux

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

In the configuration file opened above, search for requirepass foobared and uncomment it by removing the # symbol then replace foobared with your 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.
# The requirepass is not compatable with aclfile option and the ACL LOAD
# command, these will cause requirepass to be ignored.

requirepass YourStrongPassword 

# New users are initialized with restrictive permissions by default, via the
# equivalent of this ACL rule 'off resetkeys -@all'. Starting with Redis 6.2, it
# is possible to manage access to Pub/Sub channels with ACL rules as well. The
# default Pub/Sub channels permission if new users is controlled by the 
# acl-pubsub-default configuration directive, which accepts one of these values:
  • Restart Redis to apply changes.
sudo systemctl restart redis
  • When you connect again to Redis to do the ping test you will be required to authenticate with your password.

Sample output> ping
(error) NOAUTH Authentication required.> auth YourStrongPassword
OK> exit
