Can´t set root password when installing MySQL server

Estimated strength of the password: 100 Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : y … Failed! Error: SET PASSWORD has no significance for user ‘root’@‘localhost’ as the authentication method used doesn’t store authentication data in the MySQL server. Please consider using ALTER USER instead if you want to change authentication parameters.

Hello there,

For fresh installations of MySQL, you’ll want to run the DBMS’s included security script. This script changes some of the less secure default options for things like remote root logins and sample users.

Run the security script with sudo:

sudo mysql_secure_installation

This will take you through a series of prompts where you can make some changes to your MySQL installation’s security options.

Hi @heusmich,

You need to change the authentication parameters, to do so just run this command first.

$ sudo mysql

Then run This ALTER Query to change the authentication parameters.

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password by 'mynewpassword';

And now, you are able to run mysql_secure_installation command.

$ sudo mysql_secure_installation

Hope that solve your issue,
