将discuz数据表存储引擎从MYISAM转换成INNODB
由于看上了innodb的行锁对论坛的优越性，所以就手动的将discuz的数据表更换掉。
我们需要将当前需要转换的数据库备份一遍，以防中途出现以外或者不想用了直接覆盖回去。
下面就开始转换工作。
首先登录进mysql 的控制台
mysql -u root -p
输入数据密码
然后切换到论坛所用的数据库
use discuz;
显示所有表名
show tables;
复制所有列出来的表名
然后在表名前面加上
ALTER IGNORE TABLE
后面加上
CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;
合起来就是类似这样的
ALTER IGNORE TABLE uc_admins CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;
然后执行所有语句，数据表的引擎就修改好了
不过还有一个别忘记了 就是本身数据库的引擎
ALTER DATABASE discuz DEFAULT CHARACTER SET utf8;
附上discuzX2 的数据库转换代码
ALTER DATABASE discuz DEFAULT CHARACTER SET utf8; ALTER IGNORE TABLE pre_activity_pinnedsites CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci; ALTER IGNORE TABLE pre_common_addon CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;

后记
由于discuzX2.5使用了联合主键，所以不能通过单修改数据库引擎的方式来实现。
如果确实想使用，可以参考下康盛出的扩展框架 和 innodb补丁
