У меня есть сервер Ubuntu 16.04 с ISPConfig 3.1.
По какой-то причине сервер слишком много работал над процессом с высокой нагрузкой, поэтому я выключил и перезапустил машину. После этого Mysql перестал работать и больше не мог быть перезапущен.
Я проверил журнал ошибок в /var/log/mysql/error.log, но он пуст.
Когда я попытался перезапустить службу, я получил следующие сообщения:
Job for mysql.service failed because the control process exited with error code. See "systemctl status mysql.service" and "journalctl -xe" for details.
systemctl статус mysql.service:

Однако мне удалось перезапустить службу после того, как я попробовал решение из этого поста:
https://askubuntu.com/questions/1008298/cant-start-mysql-server-database-corruption
Итак, я установил:
[mysqld]
innodb_force_recovery = 9
Однако это не работает должным образом, поскольку некоторые таблицы базы данных теперь доступны только для чтения.
Что мне делать вместо этого? Спасибо.
