Answer 1

我只是通过删除并重新下载 xampp 来解决问题，有时从 0 重新开始是最好的解决方案。

Answer 2

解决方案只是一个

Copy From ...xampp/mysql/backup/... of all files and paste into .../xampp/mysql/data/  -> you will lost your data

Just copy the folder From ...xampp/mysql/backup/ & Paste into .../xampp/mysql/data/  -> this will help to run Mysql & existing database is working

Answer 3

从 xampp/mysql/backup/ 复制所有文件和文件夹并将其粘贴到 xampp/mysql/data/。如果要求替换而不是单击全部替换

Answer 4

这是由于 C:\xampp\mysql\data\mysql 中的某些文件已损坏。

解决方案:

备份C:\xampp\mysql\data
复制所有文件C:\xampp\mysql\backup
粘贴并替换现有文件：C:\xampp\mysql\data，except ibdata1 文件.
离开 ibdata1 将有助于防止 table 不存在错误。

Answer 5

只需编辑来自 my.ini 的这一行：

;脚本可能消耗的最大内存量 (128MB) ; http://php.net/memory-limit memory_limit=128M -> 选择你想要的大小。

Answer 6

对于我来说，我备份了data文件夹，然后将/backup/中的文件和文件夹复制到/data/中，服务启动成功。我不需要从我的备份数据中复制任何东西，除了 ibdata1 没有它抱怨表不存在。

Answer 7

删除或移动 ib_logfile0 和 ib_logfile1 到备份文件夹..并尝试重新启动 Mysql 这将恢复这些文件，mysql 应该运行而不会丢失任何数据。

Answer 8

@tobiloba 的解决方案是临时的。我有类似的问题。并且将通过他的解决方案暂时解决。但是在 mysql 的下一次开始。它失败了。因为我需要保留我的数据并打开 mysql 服务器以 [=29=] 它。

从 xampp/mysql/bin/my.conf 打开你的 my.conf 并找到这两行。

innodb_buffer_pool_size=10M

将其更改为 30M 0r 50MB。比

 innodb_data_file_path=ibdata1:20M:autoextend

也改变这个

 innodb_data_file_path=ibdata1:60M:autoextend

对我来说，它永久地解决了这个问题，让我现有的数据保持活跃，之后工作正常。

Answer 9

我以前遇到过这种情况，解决方案非常简单。请仔细阅读所有步骤：

备份此文件夹 C:\xampp\mysql\data（确保备份文件夹的名称不是 backup）。
现在从 C:\xampp\mysql\backup 复制所有 files/folders 除了 ibdata1 以避免错误 table 不存在。
粘贴所有复制的files/folders到C:\xampp\mysql\data

希望您的问题得到解决。

Answer 10

此解决方案将有助于保护您现有的数据库。

Just copy the folder From ...xampp/mysql/backup/ & Paste into .../xampp/mysql/data/  -> this will help to run Mysql & existing database is working
