Bagaimana cara mereset kata sandi root di MySQL 8.0.11?

sebagai di sini mengatakan:

1.jika Anda dalam mode skip-grant-tables
di mysqld_safe:

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

dan kemudian, di terminal:

mysql -u root

di mysql:

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

2.tidak dalam mode skip-grant-tables
hanya di mysql:

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