MySQL 启动时禁用了 InnoDB 引擎的解决方法
2021-07-14

从本地数据库复制表数据到虚拟机上的数据库时,得到提示:

Unknown table engine 'InnoDB'

 

于是在服务器 MySQL 中查看了引擎:

mysql> show engines\G

得到:

     Support: DEFAULT
     Comment: MyISAM storage engine

在 InnoDB 的 Supports 为 NO

 

解决方法是,编辑 my.cnf

[root@localhost mysql]# vim /etc/my.cnf

把其中 innodb = OFF 改为 innodb = ON

同时把 skip-innodb 注释掉即可。
