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:)

我以前也遇到过同样的问题。我有一台旧笔记本电脑，上面几乎所有的端口不是被阻塞就是故障了。我是这么做的。

打开XAMPP控制面板。 点击Config 然后进入Apache httpd.conf文件。用文本编辑器打开它。 搜索“80”(按Ctrl + F并找到所有它们。将其替换为8080或4040或4000)。 保存文件。并重新启动XAMPP。

它对我很有效，我希望它也能帮助到你。

发生这种情况是因为默认端口80被Apache阻塞。您需要更改端口或使端口可访问。

转到Apache安装中的Apache配置(httpd.conf)文件。

找到这些台词:

#

听192.168.1.2:80

听80

#

这里192.168.1.2是我的私有IP地址。根据你的改变。

变更如下

听192.168.1.2:8081

听8081

现在，当您访问localhost时，您必须显式地将端口添加为 http://localhost: 8081 /…

你可以采用上面提到的解决方案。这个问题可以通过修改你的“httpd.conf”(C:\xampp\apache\conf\httpd.conf)文件和“httpd-ssl.conf”(C:\xampp\apache\conf\extra\httpd-ssl.conf)文件来解决。 如果问题仍然存在，你可以检查你的skype端口。

But in my case this was different. I had to make changes in "server.crt"(C:\xampp\apache\conf\ssl.crt\server.crt) file.Try running your xammp apache from the command line in administration mode. "C:\xampp\apache\bin\httpd.exe" This will give you the errors -in which file and -which line. Likewise, I had an error in server.crt file which was blank. If you have xammp running in any other system, just copy the contents of this file(C:\xampp\apache\conf\ssl.crt\server.crt) and paste in your server.crt file and You are Done!

在我的情况下，端口已经被windows IIS服务使用。 您可以从cmd检查端口是否已被使用。打开cmd，执行如下命令:

netstat -ano

如果IIS正在使用它，可以通过以下命令停止它。以管理员身份打开cmd，然后:

iisreset /stop

现在尝试运行XAMPP，它应该可以工作。

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.
