=== MySQL - не стартует с ошибкой InnoDB: Error: could not open single-table tablespace file ===


Ошибка при запуске MySQL сервера -  '''InnoDB: Error: could not open single-table tablespace file ./db_shop1/kmkx5_redcore_translation_tables.ibd''':
 InnoDB: The error means the system cannot find the path specified.
 InnoDB: If you are installing InnoDB, remember that you must create
 InnoDB: directories yourself, InnoDB does not create them.
 InnoDB: Error: could not open single-table tablespace file ./db_shop1/kmkx5_redcore_translation_tables.ibd
 InnoDB: We do not continue the crash recovery, because the table may become
 InnoDB: corrupt if we cannot apply the log records in the InnoDB log to it.
 InnoDB: To fix the problem and start mysqld:
 InnoDB: 1) If there is a permission problem in the file and mysqld cannot
 InnoDB: open the file, you should modify the permissions.
 InnoDB: 2) If the table is not needed, or you can restore it from a backup,
 InnoDB: then you can remove the .ibd file, and InnoDB will do a normal
 InnoDB: crash recovery and ignore that table.
 InnoDB: 3) If the file system or the disk is broken, and you cannot remove
 InnoDB: the .ibd file, you can set innodb_force_recovery > 0 in my.cnf
 InnoDB: and force InnoDB to continue crash recovery here.


означат, что база db_shop1 - битая. <br />
Решение - '''переводим сервер в режим innodb_force_recovery=1, делаем бекап  этой БД, удаляем ее и запускаем сервер в нормальном режиме''':
 # vi /etc/my.cnf.d/server.cnf
 [mysqld]
 innodb_force_recovery=1
 # systemctl restart mysql
 # mysqldump db_shop1 > /root/db_shop1.sql
 Далее удаляем db_shop1 и убираем опцию innodb_force_recovery, запускаем сервер MySQL.
 После этого создаем БД db_shop1 и делаем импорт из бекапа.
