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

解决方案1：找到并停止冲突程序 重启Apache服务器

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 1234

3、接下来，httpd.conf 文件中查找 rverName localhost:，将其设置为新端口号

ServerName localhost:1234

4、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 1443

7、 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
