XAMPP 服务器错误：MySQL 意外关闭答案

【问题标题】：XAMPP Server Error: MySQL shutdown unexpectedlyXAMPP 服务器错误：MySQL 意外关闭
【发布时间】：2015-08-11 17:27:16
【问题描述】：

不确定究竟是什么导致了这个错误以及如何纠正这个错误。我想这是因为端口冲突或运行了多个 mysqld 实例，但不确定如何防止（无论哪个）应用程序用完端口。

当我检查 netstat(XAMPP) 时，它显示端口 3306 被 mysqld.exe 使用（我应该释放那个端口吗？如果可以怎么办？）

或

更改 MYSQl 端口是否可以解决此错误？如果有怎么办？

注意：这是一台访客 PC，因此不确定该系统中已经安装了哪些所有应用程序，或者该系统之前是如何配置的。

请从下面的 XAMPP 中找到错误日志。

提前感谢您的帮助。欣赏它。

【问题讨论】：

使用 lsof -i TCP:3306 检查哪个程序绑定了端口 3306 99% 确定这是因为您已经在该端口上运行 MYSQL Server。更改目标端口，或停止其他服务器
@NickRobins 感谢您的意见。它不是一台熟悉的 PC，因此不确定哪个应用程序正在使用该端口。还请描述“如何？”为您的建议。我不是这方面的专家。我在命令提示符中输入了您建议的内容（出现错误）： *********************************** ************************* Microsoft Windows [版本 6.1.7601] 版权所有 (c) 2009 Microsoft Corporation。版权所有。 H:\>lsof -i TCP:3306 'lsof' 不是内部或外部命令、可运行程序或批处理文件。 ****************************************************** ***

【解决方案1】：

根据你的说法，你已经检查了端口，发现它已经被占用了。所以我建议你改变端口。如果你想改变默认端口（不推荐）。请在mysql的实例路径中找到my.ini，例如D:\ProgramData\MySQL\MySQL Server 5.6\my.ini。然后像这样编辑 [client] 和 [mysqld] 下面的端口：

[client]
no-beep
# pipe
# socket=0.0
port=3306 #change to 3307
...
[mysqld]
...
# The TCP/IP Port the MySQL Server will listen on
port=3306 #change to 3307

然后保存，重启服务。

顺便说一句，如果你想在不同的端口上运行不同的mysql，你应该做更多的事情。
