如何解决重新安装期间无法配置MySQL
我在 Windows 10 计算机上拥有的MysqL服务突然停止并拒绝再次启动。我尝试了许多不同的选项来修复它，但是它们都没有用，所以我决定卸载MysqL并重新安装它。
- C：\ Program Files \ MysqL \
- C：\ ProgramData \ MysqL \
- C：\ Users [用户名] \ AppData \ Roaming \
- C：\ Program Files（x86）\ MysqL \
在重新安装期间，我注意到Connector .NET无法安装。
我不确定这是否是问题发生的原因，但是安装程序已多次失败配置的“备份MysqL数据库”步骤。每次运行它时，它都会显示以下错误消息：

Warning: There may be some errors thrown by MysqL Server,the MysqL_upgrade tool is going to be run next to attempt to fix database incompatibilities.

我无法跳过配置，因为MysqL仍然没有作为服务出现。
我尝试在C：\ ProgramData \ MysqL \ MysqL Server 8.0 \中手动创建数据文件夹，但这仍然不能解决问题。谁能告诉我为什么我会收到此错误？
