Сбросить пароль пользователя root MySQL не работает

Question

Я установил MySQL на свой Mac некоторое время назад, и я забыл, что такое мой пароль root (есть только несколько сочетаний паролей, которые я использую, и ни один из них не работает) ve пробовал много методов, включая попытку сброса пароля root в безопасном режиме. Ничто, кажется, не работает для меня.

Ниже журнала, который я получил от нескольких решений я пытался:

Войти 1. Нормальные

Yorks-MacBook-Pro:~ yorkwang$ mysql -u root ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO) 

Yorks-MacBook-Pro:~ yorkwang$ mysql -u root -p Enter password: ERROR 1045 (28000): Access denied for user 'root'@'localhost' (usingpassword: YES)

Answer 1

Когда вы пытаетесь запустить сервер MySQL без таблиц привилегий, вы получаете (несколько) Permission Denied. Например,

/usr/local/bin/mysqld_safe: line 135: /usr/local/var/mysql/Yorks-MacBook-Pro.local.err: Permission denied 

и поэтому вы не можете подключиться к серверу (у него никогда не было возможности начать работу).

Итак, в первую очередь, убить любого mysqld_safe, которые могли бы быть уже запущен (как суперпользователя):

$ sudo killall -TERM mysqld_safe; sleep 5; sudo killall -TERM mysqld 

Проверьте, если процесс мертв:

$ ps -ef | grep mysql 

Если нет, и если вы не заботитесь о потере целостности базы данных (возможная потеря данных) выдать команды:

$ sudo killall -KILL mysqld_safe; sleep 5; sudo killall -KILL mysqld 

Затем попробуйте запустить mysqld_safe с супер-пользователя привилегии (обратите внимание на --skip-грант-таблиц):

$ sudo mysqld_safe --skip-grant-tables 

Затем подключаются к серверу MySQL (избегая использования MySQL Unix сокет):

$ mysql -uroot -h 127.0.0.1 --protocol=tcp 

А потом, под MySQL консоли:

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass'; 
mysql> ALTER USER 'root'@'127.0.0.1' IDENTIFIED BY 'MyNewPass';
