Я действительно новичок в этом. Я пытался создать условия для изучения Rails, и я не могу пройти Mysql! Мне абсолютно нужна помощь!
Я пытался в течение 2 дней решить проблему Mysql "Доступ запрещен для пользователя 'root' @ 'localhost'", но безуспешно. Я уже «решил» три связанные проблемы: создал необходимый каталог, изменил сервер на localhost и защитил доступ к root, изменив пароль. Теперь кажется, что проблема в database.yml, так как я видел, что пароль пуст. Но я не могу изменить его с помощью config/database.yml, я вижу это с помощью cat config/database.yml.
Кроме того, просто чтобы прояснить ситуацию, я могу сделать так, чтобы она отображалась только в моем браузере, используя rails s -b 0.0.0.0, а не только rails s.
Вот что мне кажется, когда я бегу и пытаюсь получить к нему доступ:
