推荐答案
文件没有损坏.您可以使用perror"找出这些错误的来源.即
The file is not corrupt. You can find out the source of these errors with 'perror'. i.e.
toaster:~ morgo$ perror 13
OS error code 13: Permission denied
InnoDB 具有损坏检测功能(页面校验和)，并且很乐意告诉您这是否是问题所在.
InnoDB has corruption detection (page checksums) and would happily tell you if that were the problem.
目录权限已更改，或者您的 my.cnf 文件已被处理，并且它正在尝试在其他地方重新创建数据文件.
Either the directory permissions have changed, or your my.cnf file has been hosed, and it's trying to recreate data files somewhere else.
