修复XAMPP安装过程中 因端口80被占用 Apache无法启动的问题
Fix XAMPP Apache Not Starting Because Port 80 In Use
XAMPP中Apache服务器无法启动，出现该问题的最常见原因是由于默认端口号80可能已被其他程序（如Skype，Teamviewer等）使用。
得到了以下消息，其中说明了另一个程序使用的80端口

I can not understand how to solve it. Any body help me, please.

如果您仔细阅读此XAMPP消息，您将看到他们提供解决方案 - 卸载/禁用或重新配置阻止程序。一般来说，Apache最常见的冲突程序是Skype， 如果是这种情况 退出/停止 Skype并重新运行Apache查看。 我还听过Teamviewer，Microsoft Internet Server等其他程序也使用端口80并妨碍Apache启动。
然而，这并不是最佳解决方案。 如果今天这个程序妨碍Apache启动，明天那一个程序（甚至像Windows Web发布服务等服务）同样也可以使用相同的端口妨碍Apache运行。
解决方案2：更改XAMPP 中 Apache Server的默认端口80,443
因此，像EL.Web.ID和Geethika这样的最佳解决方案是重新配置XAMPP Apache服务器以侦听和使用不同的端口号。
1、首先，您需要打开Apache 的配置文件 httpd.conf并将其配置为在新端口号上使用/监听
单击并打开XAMPP控制面板Apache的 Config 按钮， 在打开的弹出菜单中，单击并打开 httpd.conf
2、在 httpd.conf 文件中搜索 listen，定位到类似这段代码位置
#Listen 12.34.56.78:80
Listen 80将端口号更改为你选择的（如端口1234），如下所示
#Listen 12.34.56.78:1234
Listen 12343、接下来，httpd.conf 文件中查找 rverName localhost:，将其设置为新端口号
ServerName localhost:12344、保存并关闭 httpd.conf 文件
5、再次单击并打开XAMPP控制面板Apache的 Config 按钮，并打开 httpd-ssl.conf 文件
6、同样地，在 httpd-ssl.conf 文件中搜索 listen，将
Listen 443修改为
Listen 14437、 接下来，httpd-ssl.conf 文件中搜索 <VirtualHost _default_:443>，将其设置为新端口号 (如1443)
同样地，在其中搜索 ServerName
ServerName www.example.com:443 or ServerName localhost:433将 ServerName 修改为新端口号(如1443)
8、保存并关闭 httpd-ssl.conf 文件
9、最后，还有一个地方你应该去改变端口号。
单击并打开XAMPP控制面板Apache的 Config 按钮，然后单击 Service and Port Settings 按钮，选中 Apache 选项卡，然后在 main port 和 SSL port 框中输入并保存新端口号 (1234，1443)。
如果一切顺利，您的Apache服务器应该便正常启动了，XAMPP控制面板中的 Apache 端口号 已更改为您设置的新端口号
