mysql卸载
在使用MYSQL数据库时,经常因为root密码或字符编码等一系列问题,需要重新安装MYSQL数据库,但是由于服务的问题,经常导致删除卸载不完整,所以请根据以下步骤操作,达到完全删除MYSQL系统的操作。
1 在控制面板里选择程序的卸载操作;
2 到安装目录,删除my.ini配置文件;
3 进入注册表文件regedit:
删除
HKEY_LOCAL_MACHINE/SYSTEM/ControlSet001/Services/Eventlog/Application/MySQL
HKEY_LOCAL_MACHINE/SYSTEM/ControlSet002/Services/Eventlog/Application/MySQL
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Eventlog/Application/MySQL
如果没有对应的键值,说明已经删除了,但是必须详细确认。
4 删除C:/Documentsand Settings/All Users/Application Data/MySQL 这个目录,不同的系统(XP,7)可能有不同,但大致都是在用户-application Data目录里,注意打开文件夹选项的显示隐藏文件,7的话会提示没有权限访问,可选择右键:管理员取得所有权,即可解决。
以上4步操作完成,重新安装数据库,当输入root密码时不提示先输入原密码,则说明之前的已经完整删除了。
