我想制作自己的wiki供个人使用，并将其放在外部驱动器上。我正在使用Windows 10。
昨天，我将XAMPP便携式安装到外部驱动器上，并设置了MediaWiki，一切都很好。我在没有关闭apache和mysql的情况下关闭了电脑，今天早上醒来继续工作，但mysql无法启动。我还没有备份，因为我最近刚刚在昨天晚上做了备份，所以我不会因为失去我写的几篇文章而感到太沮丧。

我试着查看ibdata1，作为管理员，我应该完全控制它，所以我不确定为什么会出现这个错误。
关于如何解决这个问题，我有什么选择？
也许您有现有的mysql进程正在运行，请转到任务管理器禁用它。
当我试图将密码重置为MySQL时，也遇到了类似的问题。我使用的是Windows电脑。我进入了管理工具->服务，然后停止MySQL任务。然后我没有收到错误消息："ibdata1’必须是可写的">
