Hoe het root-wachtwoord in MySQL 8.0.11 opnieuw in te stellen?

als hier zegt:

1.als je in de modus skip-grant-tables
in mysqld_safe:

UPDATE mysql.user SET authentication_string=null WHERE User='root';
FLUSH PRIVILEGES;
exit;

en dan, in terminal:

mysql -u root

in mysql:

ALTER USER 'root'@'localhost' IDENTIFIED WITH caching_sha2_password BY 'yourpasswd';

2.niet in skip-grant-tables-modus
alleen in mysql:

ALTER USER 'root'@'localhost' IDENTIFIED WITH caching_sha2_password BY 'yourpasswd';
