最佳回答：

今天在啟動myql時候突然報了一個這個錯誤，感覺非常的奇怪，想起我唯一做了的改變就是把系統臨時文件夾改了到了我用內存虛擬出來的硬盤分區裡面，估計和這個是有關系的，

處理辦法：1：打開my.ini文件
2：添加一句 tmpdir = e:/mysqltem 你的臨時文件夾 重啟mysql 搞定了

安裝完MySQL後啟動時失敗，查看應用程序日志，提示

Plugin 'FEDERATED' is disabled

再看配置文件my.ini

裡邊把 datadir 都指向C盤去了

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

但我的MySQL是安裝在D盤的，於是修改之：
datadir="D:/MySQL/MySQL Server 5.5/Data/"
然後再把C盤指向的MySQL整個文件夾刪除，重啟服務，OK
