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

  1. First Of all, You need to kill the mysql_secure_installation process. You need to run this command.
sudo killall -9 mysql_secure_installation
  1. Then You need to Set Password for the root user. First of all connect mysql server as root user.
sudo mysql

3.Now, You need to add a password for the root user with this command. NOTE: Replaceyour_new_strong_passwordWith Your Password.

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'your_new_strong_password';
  1. Now exit from MySQL login.
exit;
  1. Now, You can run mysql_secure_installation command without facing any error.
sudo mysql_secure_installation
  1. Your error is resolved now. Source Of This Information https://perfectans.net/question/12/set-password-has-no-significance-for-user-root-localhost-as-the-authentication-method-used-doesn-t-store-authentication-data-in-the-mysql-server

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.
