Can´t set root password when installing MySQL server

Posted May 11, 2022
MySQL

Hi,

When I try to setup a root password for the MySQL server following this guide (https://www.digitalocean.com/community/tutorials/how-to-install-linux-apache-mysql-php-lamp-stack-on-ubuntu-20-04) I always get the following error message: … 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. So I can´t proceed with the installation. Does anybody know how I can solve this problem?

Best regards heusmich

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,
