在my.ini(linux下/etc/my.cnf)加上skip-innodb，就可以了。
我這樣設置後，在linux下都沒問題，今天在我本機winXP啟動MYSQL，提示啟動不起來。看下mysql目錄的錯誤日志：

090613 10:15:27 [ERROR] Default storage engine (InnoDB) is not available
090613 10:15:27 [ERROR] Aborting
090613 10:15:27 [Note] C:\www\mysql\bin\mysqld-nt: Shutdown complete
估計是上次加了參數後，一直沒啟動起來。。。已經很久沒用本機的mysql了。
查了下，原來my.ini裡有一句：default-storage-engine=INNODB，把默認的engine設為INNODB，而我又加了skip-innodb，怪不得啟不來了。
將default-storage-engine改為MYISAM，MYSQL啟動OK！
在skip-innodb下，data目錄下的ibdata1,ib_logfile0,ib_logfile1這三個文件就不需要了，就可以刪除。
測試了下，在沒加skip-innodb時，刪除了這三個文件，啟動時會自動創建這三個文件，日志如下：
引用
InnoDB: The first specified data file .\ibdata1 did not exist:

090613 10:19:39 [Note] C:\www\mysql\bin\mysqld-nt: ready for connections.
再刪除這三個文件，加了skip-innodb後，啟動日志：
引用
090613 10:30:12 [Note] C:\www\mysql\bin\mysqld-nt: Normal shutdown
090613 10:30:12 [Note] C:\www\mysql\bin\mysqld-nt: Shutdown complete
090613 10:30:17 [Note] C:\www\mysql\bin\mysqld-nt: ready for connections.
Version: '5.0.45' socket: '' port: 3306 Source distribution
那三個文件就不會自動產生了。
