今天在启动myql时候突然报了一个这个错误，感觉非常的奇怪，想起我唯一做了的改变就是把系统临时文件夹改了到了我用内存虚拟出来的硬盘分区里面，估计和这个是有关系的，

处理办法：1：打开my.ini文件
2：添加一句 tmpdir = e:/mysqltem 你的临时文件夹 重启mysql 搞定了

安装完MySQL后启动时失败，查看应用程序日志，提示

Plugin 'FEDERATED' is disabled

再看配置文件my.ini

里边把 datadir 都指向C盘去了

datadir="C:\Program Files\MySQL\MySQL Server 5.5\data\"

但我的MySQL是安装在D盘的，于是修改之：
datadir="D:/MySQL/MySQL Server 5.5/Data/"
然后再把C盘指向的MySQL整个文件夹删除，重启服务，OK
