用XAMPP启动MySql时报错--Using innodb_additional_mem_pool_siz_MySQL
XAMMPP Version ：xampp-win32-1.8.3-0-VC11-installer
MySQL Version:
【查看当前MySQL版本方法】
使用-V参数
首先我们想到的肯定就是查看版本号的参数命令，参数为-V（大写字母）或者--version
使用方法：
D:/xampp/mysql/bin 摘自：http://blog.163.com/magicc_love/blog/static/18585366220134159357764/ mysql_error.log 2014-02-10 16:06:35 8956 [Note] Plugin 'FEDERATED' is disabled. 尝试网上的方法后，仍然未解决： 1、运行xampp/mysql目录下的mysql_installservice.bat，弹出dos窗口后按任意键关闭。 然后再运行此目录下的mysql_uninstallservice.bat即可。 现在XAMPP的控制版面就可以成功启动MySql了。 2、在D：/ XAMPP / mysql的/ BIN下面的my.ini文件中添加 innodb_force_recovery = 1 不过位置要加在的[mysqld]中，一开始加在末尾没用处 以上两个方法未能解决，再次仔细研读log 注意到： The first specified data file F:/xampp/mysql/data/ibdata1 did not exist: a new database to be created! 思考是否是因为该文件创建有错误，导致的不能启动，于是到该路径下删除已生成的ibdata1 再次启动XAMPP中的MySQL 可启动成功，解决该问题。
