Answer 1

我遇到了类似的问题，并尝试了Fabrizio Valencia的Stack Overflow 答案。有效。

\n

\n

停在那里！请不要删除任何东西！首先尝试做我所做的事情。

\n

好的，这里列出的答案都没有解决我的问题，甚至，一些答案使我丢失了所有数据库数据。因此，我按照 XAMPP 消息面板中的错误消息的指示执行了操作。所以我这样做了：

\n

\n
1. 将文件夹重命名mysql/data为mysql/data_old（您可以使用任何名称）
\n
2. 新建一个文件夹mysql/data
\n
3. 将驻留mysql/backup在新mysql/data文件夹中的内容复制到
\n
4. 将所有数据库文件夹复制mysql/data_old到mysql/data
\n
5. 最后复制ibdata1文件mysql/data_old并将其替换到mysql/data文件夹中
\n
6. 从 XAMPP 控制面板启动 MySQL
\n

\n

并且，瞧\xc3\xa0。没有数据库丢失，没有端口更改，没有以管理员身份运行，没有强制恢复，没有终止 mysqld 进程，没有从以前的版本恢复，没有更多错误。

\n

\n

Answer 2

它对我有用（部分）：请阅读全部内容

我从“ xampp\mysql\backup ”复制了所有数据（文件夹和文件）并将其粘贴并替换为“ xampp\mysql\data ”。就这样...

注意： 请确保您在其他位置备份了这两个文件夹（“备份”和“数据”），包括文件和文件夹。以便您可以随时回滚。

警告：我遇到了另一个问题。我无法访问不同数据库中的几个表。数据库表行、类型、大小、开销列为空，排序规则列显示“正在使用”。

但是，这对我来说没关系。因为大多数人都在跑步。但是，我仍然在寻找答案。因此，我分享修复问题之前和之后的 MySQL 日志。以便它可以帮助其他人找到真正的原因。
