昨晚服务器升级了MySQL服务器，并使用了InnoDB。当MySQL服务器关闭时，Cpanel遇到了很多问题！因为VPS上的许多站点在它们的数据库中使用了InnoDB引擎表格。这些站点出现了问题，无法访问。
error: Unknown table engine 'InnoDB'
错误
它会启用mysql服务器，但没有放置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 |

在我的.cnf文件中，InnoDB的设置如下：
innodb_fast_shutdown = 0
innodb_log_buffer_size = 8M
innodb_log_file_size = 512M
感谢您，帮我解决问题。
