首先确保你的\xampp文件夹在根目录下!这很重要，因为路径是相对的。 然后确保以管理员权限运行xampp_control.exe。 然后更改下面的文件，以避免阻塞端口80的问题。

在\xampp\xampp-control.ini中应该这样设置:

[ServicePorts]
Apache=8080
ApacheSSL=4433

找到\xampp\apache\conf\httpd.conf并设置:

Listen 8080

ServerName localhost:8080

找到\xampp\apache\conf\extra\httpd-ssl.conf并设置:

Listen 4433

<VirtualHost _default_:4433>

ServerName www.example.com:4433

然后结束所有服务，以admin权限重新启动xampp-control.exe。它应该运行!

如果你正在使用Skype，你会得到这个错误。

只需按Ctrl+Alt+Del goto任务管理器选择Skype，然后单击结束任务，然后返回并启动Apache，一旦Apache启动成功。然后再打开Skype现在都将工作良好。

无需更改任何端口。

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XAMPP控制面板V3.2.1中，单击右上角的“NetStat”按钮。确保端口80没有被任何其他程序使用。然后点击它下面的“Shell”。在shell提示符中发出这个命令;

Apache_Start.bat

或者输入“ap”，然后按tab键两次，这将类似地生成上述命令。 您将看到Apache失败的确切错误。这很可能是虚拟主机配置问题或其他问题。它将显示发生错误的行号。只需要修复这个错误。注意，在RootDocument中，尾随的\也可能是错误的来源。删除任何拖尾""。

In my case I edited the http.conf file for I wanted localhost to be accessible by other computers on the network and did not set a static IP on my network adapter. I also checked netstat and saw nobody was using port 80. So I opened cmd and typed ipconfig I also opened the http.conf and searched(CTRL + F) for "Listen 80". The line above it, if not commented, enables localhost to be accessible over the network. It should look something like this:Listen 192.168.93.3:80 Comparing the result from ipconfig command, I saw that my current ip address isn't the same as the one on the http.conf file. So I changed the ip address on the http.conf file with the one currently assigned to me and it worked.

对我来说，这要容易得多。我关闭了本地windows防火墙。然后重新加载comp启动xampp并再次启动apache。然后把防火墙重新打开。
