Question

Can´t set root password when installing MySQL server

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

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,
