Question

我正在将数据库for mamp移动到我的删除驱动器，它几乎正常工作我想但每当我启动mamp mysql将无法启动，如果我检查错误日志我遇到了这个：

我也发现了这个问题但似乎无法找到让MAMP工作的方法，我做错了什么，这是一个权限问题吗？

PS - 是的，我的驱动器名为WALL-E：）

Answer 1

文件系统级文件锁定可能存在问题。尝试使用--skip-locking启动Mysql。我不知道如何使用MAMP，因为我从未使用过它。在其首选项中查找可以为启动提供自定义选项的位置。

另外，您可能需要自定义可移动媒体的安装以启用autofs锁，但我的autofs-fu很弱，所以我无法在那里给出任何指示。
