How to Change password and connect to Redis connection to server with password?

Redis server by default is not password protected.

There are two ways to change the password for the redis server.

using command line
Directly modifying redis.conf file

Redis set or change password

First check Password is set or not using the auth password command

127.0.0.1:6379> auth password
(error) ERR Client sent AUTH, but no password is set

It looks like the password is not set for the Redis server.

Let’s see how to change the password in multiple ways

using config set

With interactive cli, you can change the password using CONFIG SET

CONFIG SET requirepass "12345"

requirepass is a configuration parameter for changing the password. It is not required to have a downtime and changes the password at runtime. This will set the password for the redis server for current access only. if we restart the server, changes are lost.

To save these changes and run the below command

CONFIG REWRITE

It will work for the next restart onwards

using redis.conf file

Redis.conf file contains security related configured uncommented as seen below

Change from

# requirepass foobared

# requirepass 123467

Save the file.

Now, Restart or stop and start the server to reload changes.

Now, the Redis server is password protected.

Any client who wants to communicate with the server needs to provide the -a password option.

redis-cli -h 127.0.0.1 -p 6379  -a password
