问题现在得到解决。每个 MISAM 表在数据目录中有 3 个文件。

对于用户表,

  1. user.frm - 表元数据
  2. user.MYI - 索引
  3. user.MYD - 数据

我错过了覆盖 user.frm 文件(因为进行了 docker rw 更改)。所以 user.frm 来自 mysql-5.6 和 user.MYI,user.MYD 来自 mysql-5.5。password_expired在 5.6 中添加了 mysql 用户表。由于与 user.frm 和其他文件不兼容,它是不可恢复的。我尝试从 mysql-5.5 复制 user.frm 及其工作。
