error：MySQL意外关闭。 （我已经阅读了所有的ansewrs，但我的情况不断，这让我不知所措）

Question

首先，我检查mysql错误log

我转到MySQL数据库中的“数据”目录。
• I通过“ Data Gorg”重命名“ Data”文件夹，并在我命名的“数据”中创建其他一个，然后删除“ Data Gold”的内容，然后转到''backup''我找不到所有文件夹，我找不到全部内容
• 
然后我去回收，发现了我删除的所有数据，然后恢复了“数据”文件夹并启动XAMPP并仍然有问题扩展。

然后我在文件中将端口从3306更改为3307，然后启动Appache，MySQL和MySQL有相同的问题

然后我找到了comand求解并运行comand
• my.ini
• .\setup_xampp.bat如果您有任何想法解决问题，请访问Xampp 还有其他东西这个文件

   C:\xampp ❯ .\setup_xampp.bat

mysql_error.log

错误表示缺失/损坏的系统表（例如Mysql.Servers）。这是解决此问题的方法：=>确保通过XAMPP控制面板停止Apache和MySQL。

Answer 1

=>删除原始数据文件夹（不是备份）。

=>在c：\ xampp \ mysql中打开命令提示符：

this this创建一个带有默认系统表的新鲜数据文件夹。

=>将数据库文件夹（例如，phpmyadmin，your_database）从data-bak复制到新的数据目录中。请勿覆盖系统表（例如MySQL，Performance_Schema）。

=>修复权限：确保数据文件夹及其内容具有MySQL Service的完整读取/写入权限。

=>启动mySQL：通过XAMPP控制面板启动mySQL。再次检查错误日志以确认分辨率。
