自己用🈶的MYSQL都是用【dōu shì yòng】📕MYISAM数据库🚦，还没涉【hái méi shè】及到需要🧚INNODB，因此打算直接不加载INNODB引擎【yǐn qíng】。
在🖌my.ini(linux下【xià】😇/etc/my.cnf)加上skip-innodb，就可以【jiù kě yǐ】⛵了【le】👂。
我这样设置后【shè zhì hòu】🎑，在🖌linux下【xià】😇都没问题，今天在🏦我本机【wǒ běn jī】winXP启动【qǐ dòng】📝MYSQL，提示启动【qǐ dòng】📝不起来🎣。看下【xià】😇mysql目录的【mù lù de】错误日✅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

估计是【gū jì shì】上次加了【jiā le】👂参数后🎑，一直没✔启动【qǐ dòng】📝起来🎣。。。已经很【yǐ jīng hěn】🚛久没用🔸本机的💨mysql了【le】👂。
查了【chá le】👂下【xià】😇，原来🎣my.ini里有一句：default-storage-engine=INNODB，把默认的engine设为【shè wéi】👐INNODB，而我又【ér wǒ yòu】加了【jiā le】👂skip-innodb，怪不得【guài bú dé】启不来【qǐ bú lái】🎣了【le】👂。

将✉default-storage-engine改为MYISAM，MYSQL启动【qǐ dòng】📝OK！
在🖌skip-innodb下【xià】😇，data目录下【xià】😇的ibdata1,ib_logfile0,ib_logfile1这三个【zhè sān gè】🔆文件就【wén jiàn jiù】🆓不需要🧚了【le】👂，就可以【jiù kě yǐ】⛵删除【shān chú】📞。

测试了【le】👂下【xià】😇，在🖌没加【méi jiā】skip-innodb时，删除【shān chú】📞了【le】👂这三个【zhè sān gè】🔆文件【wén jiàn】👥，启动【qǐ dòng】📝时会自【shí huì zì】动创建这🌁三个文件【wén jiàn】👥，日志如🎊下【xià】😇：

再删除【zài shān chú】📞这三个【zhè sān gè】🔆文件【wén jiàn】👥，加了【jiā le】👂skip-innodb后🎑，启动【qǐ dòng】📝日志：
