How to set a password for Redis

There are two ways to set the redis password, one requires restarting the redis service, and the other does not require restarting the redis service. The following article will introduce these two methods to you, I hope it will be helpful to you.

Method 2: Pass Command to set password

This method is relatively simple and does not require restarting the redis service. After connecting to redis, set it through the command, as follows:

After setting, you can check the password through the following command

config get requirepass
