我一直在使用Xampp来测试我的网站内容，一切都运行良好，直到我决定安装Microsoft SQL SERVER 2017来做一些数据科学的东西（学校的东西）。
现在我仍然可以启动Apache，但我无法启动MySQL。这是日志：

我尝试使用SQL Server Management关闭SQL Server，但我仍然无法连接MySQL。
答案 0 :(得分：1)
您可以更改sql server或mysql服务器的端口，并且在访问时不要忘记指定端口。
答案 1 :(得分：0)
在日志中，当您安装SQL Server时，它“保留”了MySQL使用的相同端口
2017-11-17 13:40:06 13304 [ERROR] Do you already have another mysqld server running on port: 3306 ?
您可以在my.ini文件中更改MySql端口，该文件可以通过“配置”下的Xampp控制面板进行访问。
或者，您可以按照本教程更改de SQL Server端口：https://www.syskit.com/blog/change-sql-server-port/
答案 2 :(得分：0)
由于Microsoft SQL Server和MySQL / MariaDB / Percona使用不同的端口（并且它听起来不像默认设置），我怀疑这与您安装SQL Server有关。 SQL Server使用port 1433和MySQL port 3306。
对于使用该端口的 ，https://stackoverflow.com/a/48199/2385479可以帮助我们。有TCPView Sysinternals应用程序的建议或使用netstat的替代建议（例如C:\> netstat -a -b -n），它可以让您了解使用端口3306的内容。
在我看来，您可能安装了另一台与XAMPP尝试使用的端口冲突的MySQL服务器。
