卸载MySQL5.0_MySQL

Jun 01, 2016 am 11:52 AM

昨天在Navicat for mysql中导入一个脚本,运行,出现乱码。
考虑到可能是版本问题,就想卸载了重新安装MYSQL,这一卸载倒是出了问题,导致安装的时候安装不上。
  后来无意发现是卸载的时候没有卸载完全导致,下面给出完整的卸载MySQL 5.1的卸载方法:

  1、控制面板里的增加删除程序内进行删除

  2、删除MySQL文件夹下的my.ini文件,如果备份好,可以直接将文件夹全部删除

  3、开始->运行-> regedit 看看注册表里这几个地方删除没有

  HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Eventlog\Application\MySQL 目录删除

  HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\Eventlog\Application\MySQL 目录删除

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application\MySQL 目录删除(我卸载的时候没有找到,略过后仍达到完全卸载的目的。)

  4、这一条是很关键的

  C:\Documents and Settings\All Users\Application Data\MySQL(win7 中即使有管理员权限也打不开C:\Documents and Settings\All Users\,这个路径相当于C:\user\All Users\)

  如果这里还有MySQL的文件,必须要删除。(我的文件夹没有东西)

  注意:Application Data这个文件夹是隐藏的,需要打开个文件夹选择菜单栏 工具→文件夹选项→查看→隐藏文件和文件夹 一项选上 显示所有文件和文件夹 确定

4步完成后,重启 OK!再次安装吧。

首先, 查看mysql数据库安装时候选择的编码格式 :
