Отвалилась база данных

[zharinov]

Пару недель назад перенес сюда на стартовый тариф VDS Старт штук 6 сайтов на Друпале,
Все работало нормально, внезапно вчера на всех перестала грузится база данных,
и смена тарифа вообще никак не помогла.

Что подсказывает гугл - не помогает.

Как найти причину, что делать?

---------------------------

PDOException: SQLSTATE[HY000] [2002] Connection refused in lock_may_be_available() (line 167 of /home/admin/web/MYDOMEN.ru/public_html/includes/lock.inc).

У вас побились таблицы формата Innodb.
Вот хорошая инструкция как восстановить такие таблицы:
https://habrahabr.ru/company/kingservers/blog/257627/

Если у вас есть бэкапы баз и потеря последних данных вам не критична, то можно просто удалить/перенести файлы
/var/lib/mysql/ibdata1
/var/lib/mysql/ib_logfile0
/var/lib/mysql/ib_logfile1
Запустить MySQL и восстановить базы из бэкапов.
