【问题描述】：

我的 mysql 无法启动，它显示如下：

12:50:50  [mysql]   Error: MySQL shutdown unexpectedly.
12:50:50  [mysql]   This may be due to a blocked port, missing dependencies, 
12:50:50  [mysql]   improper privileges, a crash, or a shutdown by another method.

然后这是错误日志：

这些错误的原因是什么，我该如何纠正它们？

【参考方案1】：

关于这个问题，请访问：

c:\xampp\mysql\data\

并删除除目录之外的所有文件。

以防万一保留my.ini，如果再次出错，请删除my.ini。

【讨论】：

尝试更改mysql端口可能另一个程序正在使用相同的端口号

怎么样？更改mysql端口？

你拯救了这一天。我的备份软件损坏了 mysql/data 文件，尤其是 ibdata。我删除它并重新运行。它创建了新文件并启动了服务器

【参考方案2】：

非常非常简单

打开 xampp > mysql > 备份从备份文件夹复制所有内容并将所有内容粘贴到从备份文件夹复制的数据文件夹中

重新启动 xampp 并全部启动。谢谢。

这是非常简单的方法。

如果这很容易，问题可能不在***上。说某事很容易是非常主观的。一个很好的解释它是如何工作的，通常效果最好
