自己用的MYSQL都是用MYISAM數(shù)據(jù)庫，還沒涉及到需要INNODB，因此打算直接不加載INNODB引擎。
在my.ini(linux下/etc/my.cnf)加上skip-innodb，就可以了。
我這樣設(shè)置后，在linux下都沒問題，今天在我本機(jī)winXP啟動MYSQL，提示啟動不起來?？聪耺ysql目錄的錯(cuò)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(jì)是上次加了參數(shù)后，一直沒啟動起來。。。已經(jīng)很久沒用本機(jī)的mysql了。
查了下，原來my.ini里有一句：default-storage-engine=INNODB，把默認(rèn)的engine設(shè)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(gè)文件就不需要了，就可以刪除。

測試了下，在沒加skip-innodb時(shí)，刪除了這三個(gè)文件，啟動時(shí)會自動創(chuàng)建這三個(gè)文件，日志如下：

再刪除這三個(gè)文件，加了skip-innodb后，啟動日志：

那三個(gè)文件就不會自動產(chǎn)生了。
