MSQL出错日志里出现类似下面的错误提示：

InnoDB: Attempted to open a previously opened tablespace. Previous tablespace mysql/slave_relay_log_info uses space ID: 3 at filepath: .\mysql\slave_relay_log_info.ibd. Cannot open tablespace wordpress/wp_terms which uses space ID: 3 at filepath: .\wordpress\wp_terms.ibd

解决办法：

在 my.ini 文件添加如下代码：

innodb_force_recovery = 1

要独立一行
