XAMPP Windows上的MariaDB无法启动

10个月前，我已经在Windows上安装了XAMPP版本：7.3.6，到目前为止一切正常。

今天看起来MariaDB（MySQL）无法启动。

检查error_log是否有错误消息：

因为几天前我已经在同事的笔记本电脑上修复了这个问题，所以今天我要回答我自己的问题。我正在尝试重现此修复程序。

因此mysql_error文件中没有错误消息。

但是当查看数据目录C:\xampp\mysql\data时，它看起来有点奇怪：

您可以看到“普通的东西”，数据库目录和数据文件，然后看到很多奇怪的文件，其中包含很多@。

所以我接下来要做的是清理该目录：

08/11/2019  16:53    <DIR>          .
08/11/2019  16:53    <DIR>          ..

19/06/2019  19:28    <DIR>          test

如您所见，数据库目录中的一部分，我剩下的唯一文件是：

08/11/2019  16:51            16.384 aria_log.00000001
08/11/2019  16:51                52 aria_log_control
08/11/2019  16:51        79.691.776 ibdata1
08/11/2019  16:51             2.137 ib_buffer_pool

因此，我已经删除了这些奇怪的文件，并且还删除了我从以前的经验中知道的InnoDB日志文件，有时它们可能会引起问题。

现在我已经从Xampp启动了MariaDB并开始工作！

我的假设不知道是什么原因

可能是计算机的严重关机损坏了InnoDB日志文件，之后，当您尝试启动时它崩溃了，并生成了那些“主/中继”文件。

也许对MySQL / MariaDB更熟悉的人可以指出“原因”。
