有时问题不是端口问题，但可能是由于您所做的错误配置，Apache没有在Windows的事件查看器中记录错误。简单地说

cd C:\xampp\apache\bin

然后运行

httpd.exe

Apache会为你吐出错误，如下所示

AH00526: Syntax error on line 2 of C:/xampp/apache/conf/httpd.conf: Invalid command 'This', perhaps misspelled or defined by a module not included in the server configuration

我希望这能帮助一些可怜的人:)

在我的情况下，这发生在安装sql server和解决方案是在这个答案中描述

Xampp -安装SQL Server和Visual Studio后无法启动Apache

所以我不得不从Windows服务中禁用“SQL Server Reporting Services”服务

我收到了上面相同的错误，导致我的原因是在文件'httpd-vhosts.conf'中，我在<Directory>标签中放了一个注释，就像这样…

<Directory "*PATH TO MY FOLDER*...">
        AllowOverride All
        Require all Granted    ## This directive could/should be set to denied.
</Directory>

一旦我删除了注释，Apache就启动了。我想我应该把注释放在它自己的行里。我只是想，像其他网络代码一样，它可以在那里。

如果上面所有的答案都不奏效，那么就这么做。注释掉php.ini文件中的所有扩展名。

In xampp control panel, click on Apache config. click on php.ini In php ctrl + F (extension) to find all extensions in your php.ini Comment out each and every active extension by adding a ; at the start of each extension line. example ;;;extension=bz2 i put 3 ;;; because i wanted to know ones i commented out so that when i come back to deburg which one had a problem, it was easy for me to see which ones i commented out. Make sure all extensions=whatever are commented out. Run your apache server. To pickup which extension was the problem, one by one un-comment your extensions while restarting your server until you catch the culprit.

如果你用的是Windows 7。在Windows搜索中搜索IIS(单击左下角的窗口图标，并键入“搜索程序和文件”)。

打开IIS (Internet信息服务)。

在右侧的操作面板。单击停止。

注意:停止链接在屏幕截图中是褪色的。就像我阻止了它一样。 问题解决了!

我遇到了同样的问题，结果是我忘记运行setup_xampp.bat(可移植版本)。
