Can'；t运行XAMPP-MySql

当我尝试启动XAMPP-MySql时，它不起作用。 我已经尝试过修复它，但是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

我只是通过再次删除和下载xampp进行了修复，有时从0重新开始是人们能找到的最好的解决方案。

该解决方案只是一个简单的解决方案

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

---

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”

，这是由于C:\xampp\mysql\data\mysql中的某些文件损坏所致

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：C:\xampp\mysql\data中的现有文件，但ibdata1文件除外。
离开ibdata1将有助于防止表不存在错误

---

只需从my.ini编辑此行：

)；脚本可能消耗的最大内存量（128MB） ;

---

内存限制=128M->选择您想要的大小。

对我来说，我备份了数据文件夹，然后将文件和文件夹复制到/backup/to/data/中，服务成功启动。我不必从备份的数据中复制任何内容，除了ibdata1，没有它，我会抱怨表不存在。

您使用的是什么XAMPP？这是在您更改密码时发生的吗？尤其是“root”？像你一样，我重新安装了，但它再次发生！请参阅错误描述是否有人对此进行解释？谢谢，这对我来说很有效，但我只从备份中复制了文件夹，因为当我从备份中复制并粘贴所有文件夹时，mysql工作正常，但数据库中的数据丢失。我建议大家尝试一下Laragon功能更强大，您将丢失数据库。检查Tobiloba的答案（）所有模式都丢失了，这使得xampp可以工作，但所有数据都丢失了！当我这么做的时候，另一个问题出现在我使用Wordpress时，它要求我重新安装Wordpress。这一个对我有效。与其他答案相比，这个答案有着最清晰和彻底的解释。谢谢你，你是救命恩人，这是我唯一尝试过的有效方法。谢谢。第三点更重要：）
