Question

昨晚服务器从MySQL服务器升级，InnoDB Cpanel在MySQL服务器关闭时出现了很多问题！因为他们的数据库中的许多网站上的InnoDB引擎表没有提出他们的网站并说

error: Unknown table engine 'InnoDB'

错误

它将启用mysql服务器，但它没有放入InnoDB！ mysql命令

show engines;

我注意到以下结果不是InnoDB结果

mysql> show engines;

 | Engine | Support | Comment | Transactions | XA | Savepoints |

 | MyISAM | DEFAULT | Default engine as of MySQL 3.23 with great performance | NO | NO | NO |
 | MRG_MYISAM | YES | Collection of identical MyISAM tables | NO | NO | NO |
 | BLACKHOLE | YES | / dev / null storage engine (anything you write to it disappears) | NO | NO | NO |
 | CSV | YES | CSV storage engine | NO | NO | NO |
 | MEMORY | YES | Hash based, stored in memory, useful for temporary tables | NO | NO | NO |
 | FEDERATED | NO | Federated MySQL storage engine | NULL | NULL | NULL |
 | ARCHIVE | YES | Archive storage engine | NO | NO | NO |

 7 rows in set (0.00 sec)

登录mysql服务器会出错...

在my.cnf innodb设置中都是：

 innodb_fast_shutdown = 0
 innodb_log_buffer_size = 8M
 innodb_log_file_size = 512M

谢谢，PLZ帮助我解决问题。

根据我在日志中看到的内容， InnoDB 由于其文件ib_logfile0混乱而中断。当硬盘崩溃导致此文件无法读取时，我遇到了同样的问题 - 在阅读了我可以形成破碎的驱动器文件的内容之后很好但内部的数据已经搞砸了。

InnoDB: Error: log file ./ib_logfile0 is of different size 0 268435456 bytes
InnoDB: than specified in the. Cnf file 0 536870912 bytes!

它是 - ＆gt;你的文件大小是256 MB，但你的配置告诉它应该是512mb大小。修复配置中的错误。

然后 - 备份所有数据（带数据的innodb表）。关闭数据库（干净关闭 - 必须完成所有事务 - 日志不应包含它们以使文件更大）。然后备份ib*文件并更改配置。重启DB。
