我想制作自己的 wiki 以供个人使用，并将其放在外部驱动器上随身携带。我正在使用 Windows 10。
我昨天将 XAMPP portable 安装到我的外部驱动器并设置了 MediaWiki，一切正常。我在没有关闭 apache 和 mysql 的情况下关闭了计算机，并在今天早上醒来继续处理它，但 mysql 无法启动。我还没有备份，因为我最近刚刚在昨天晚上备份，所以我不会因为丢失我写的那几篇文章而太难过。

我试着查看 ibdata1，我作为管理员应该完全控制它，所以我不确定为什么会收到此错误。
关于如何解决这个问题，我有哪些选择？
最佳答案
也许您有现有的 mysql 进程正在运行，请转到任务管理器将其禁用。
关于permissions - XAMPP:[错误] InnoDB:innodb_system 数据文件 'ibdata1' 必须是可写的，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/61162764/
