MySQL 5.6 禁用INNODB
INNODB是MySQL被ORACLE收购后开发的，支持事务和行级锁等高级功能，但是并不是所有人都需要INNODB的，对大部分人来说，以前的MYISAM引擎就够了，一般会选择将默认引擎改为MYISAM，但是INNODB还是会耗费内存和硬盘，这时候，就需要把INNODB彻底禁用。
在以前的MySQL中，一般可以这么设置就行了：
default-storage-engine=MYISAM skip-innodb
default - storage - engine = MYISAM
skip - innodb
但是在最新的MySQL5.6里，这么设置是没法启动的，需要再增加一句设置：
default-tmp-storage-engine=MYISAM
default - tmp - storage - engine = MYISAM
不仅如此，还需要添加以下配置，否则程序会很容易退出的：
