mysql卸载

(1) 开始-MySQL-MySQL Server 5.1-MySQL Server Instance Config Wizard--->Remove Instance。

（2）点击[开始]--[运行]，输入services.msc回车，进入服务管理窗口。

（3）服务里面找到MySQL服务，将MySQL的服务给停止。

（4）点击[开始]--[运行]，输入console回车进入控制面板，找到添加删除程序，找到MySQL选择卸载。

（5）这步很重要，之前不管我怎么卸载MYSQL清空残余文件都还是要输入原始密码，后来试试找了下注册表，清空后果然有效。
        删除注册表数据，通过regedit，删除以下几个文件【也可以在注册表里搜索mysql】：
        HKEY_LOCAL_MACHINE/SYSTEM/ControlSet001/Services/Eventlog/Applications/MySQL
        HKEY_LOCAL_MACHINE/SYSTEM/ControlSet002/Services/Eventlog/Applications/MySQL
        HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Eventlog/Applications/MySQL
        HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services一般服务会以相同的名字(名字通常是MySQL)在这里显示一个主健，直接删除相关的键值便可。

（6）最后将MySQL安装目录和保存数据库数据的目录也删除。
通常这两个目录分别在C:/program files/mysql 和 C:/Documents and Settings/All Users.WINDOWS/Application Data【或C:/Documents and Settings/All Users/Application Data】(这个目录是

不确定的，最好是在c盘里使用搜索“mysql”关键字来查找)。目录有可能是隐藏的，需要设置文件夹选项显示隐藏目录。

（7）重新启动机器。
到此原mysql已经被完全卸载。
