无法运行 XAMPP - MySql

Question

当我尝试启动 XAMPP - MySql 时它不起作用。我已经尝试修复它，但我找不到任何实际的解决方案，我希望你能找到它的问题所在。

Answer 1

这是因为C:\xampp\mysql\data\mysql 中的一些文件被破坏了。

解决方案：

1. 备份C:\xampp\mysql\data
2. 复制所有文件C:\xampp\mysql\backup
3. 粘贴并在替换现有的文件：C：\ XAMPP \ MySQL的\数据，除了为ibdata1中的文件。
   离开ibdata1将有助于防止表不存在错误。

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

我以前也遇到过这种情况，解决方案非常简单。请仔细阅读所有步骤：

1. 对此文件夹C:\xampp\mysql\data进行备份（确保备份文件夹的名称不是backup）。
2. 现在复制C:\xampp\mysql\backup中除ibdata1之外的所有文件/文件夹，以避免表不存在的错误。
3. 将所有复制的文件/文件夹粘贴到C:\xampp\mysql\data

希望您的问题能够得到解决。

Answer 4

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，请单击全部替换

Answer 5

@tobiloba 的解决方案是临时的。我有类似的问题。并通过他的解决方案暂时解决。但下次mysql启动时。它失败了。因为我需要保留我的数据并打开 mysql 服务器来运行它。

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

innodb_buffer_pool_size=10M

将其更改为 30M 0r 50MB。然后

 innodb_data_file_path=ibdata1:20M:autoextend

也改变这个

 innodb_data_file_path=ibdata1:60M:autoextend

对我来说，它永久地解决了问题，并使我现有的数据保持活力，并且之后工作正常。
