MySQL не может запуститься. [ОШИБКА] Невозможно запустить сервер: Привязка к порту TCP/IP: Нет такого файла или каталога

Question

Мой сервер MySQL не запустился. Я использовал эту настройку раньше, но сегодня она не работает.

У меня локальная конфигурация с Laragon (WAMP). Похоже, что дело в каком-то поврежденном файле, но я не могу понять, как это исправить.

У меня MySQL работает на порту 3306. Я выполнил netstat -anкоманду, но на порту 3306 нет ни одного процесса.

Вот журнал MySQL:

Answer 1

Напишите тысячу раз: «Если какая-то служба не работает, сначала проверьте брандмауэр»

Сколько времени потеряно на поиски решения! Я перезагрузил компьютер и мне высветилось сообщение Windows, предупреждающее о том, что она заблокировала mysqld.

Это потому, что в последний раз, когда я работал с локальными сайтами, я настроил Laragon на запуск при каждом запуске Windows. Этого было достаточно, чтобы брандмауэр Windows начал блокировать.

Answer 2

Если в вашей системе установлены 2 версии MySQL, измените порт более новой версии MySQL или остановите службу версии в вашей системе, чтобы освободить порт с номером 3306.
