本文介紹了Mysql入門MYSQL無法啟動提示： Default storage engine (InnoDB) is not available的解決方法，希望對您有用。如果有疑問，可以聯系我們。

在my.ini(linux下/etc/my.cnf)加上skip-innodb,就可以了.
我這樣設置后,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：
引用
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后,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里有一句：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:
InnoDB: a new database to be created!
090613 10:19:37 InnoDB: Setting file .\ibdata1 size to 10 MB
InnoDB: Database physically writes the file full: wait...
090613 10:19:37 InnoDB: Log file .\ib_logfile0 did not exist: new to be created
InnoDB: Setting log file .\ib_logfile0 size to 24 MB
InnoDB: Database physically writes the file full: wait...
090613 10:19:38 InnoDB: Log file .\ib_logfile1 did not exist: new to be created
InnoDB: Setting log file .\ib_logfile1 size to 24 MB
InnoDB: Database physically writes the file full: wait...
InnoDB: Doublewrite buffer not found: creating new
InnoDB: Doublewrite buffer created
InnoDB: Creating foreign key constraint system tables
InnoDB: Foreign key constraint system tables created
090613 10:19:39 InnoDB: Started; log sequence number 0 0
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后,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.
