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.

开放的Skype。

工具—>选项—>高级—>连接。

取消选中“使用端口80和443作为传入连接的替代”复选框

退出并关闭所有Skype窗口。尝试重新启动Apache。

对我来说，这个问题始于我在Windows 8电脑上托管vpn连接时。

简单地删除连接从“控制面板\网络和互联网\网络连接”解决了这个问题。

由于我在一个开发人员面临防火墙问题的企业环境中工作，其他答案都不能解决我的问题。

由于Skype不使用该端口，而是由其他一些内部应用程序使用， 我按照以下步骤来解决这个问题:

步骤1 -从XAMPP控制面板，在Apache下，单击Config按钮，并选择Apache (httpd.conf)。

在httpd.conf文件中，我发现了一行说:

Listen 80

然后把80换成任何你想要的数字/端口。在我的场景中，我使用端口8080。

Listen 8080

仍然从httpd.conf文件，我发现另一行说:

ServerName localhost:80

将80修改为8080。

ServerName localhost:8080

步骤2 -从XAMPP控制面板，在Apache下，再次单击Config按钮，但这次选择Apache (httpd-ssl.conf)。在httpd-ssl.conf文件中，找到这样一行

Listen 443

并将443更改为您想要的任何数字/端口。我将使用4433作为新的端口号。

Listen 4433

仍然从httpd-ssl.conf文件中，找到另一行说

<VirtualHost _default_:443>

ServerName localhost:443

将443改为4433。

<VirtualHost _default_:4433>

ServerName localhost:4433

记得在进行一些更改后保存httpd.conf和httpd-ssl.conf文件。然后重新启动Apache服务。

我的例子很简单。

我在我的以太网端口上设置了一个本地IP地址。

然后出现这个错误。结果我并没有连接 将电缆连接到它，因此IP不会解析为Apache中的IP集。

解决方案是将电缆连接到交换机或路由器。然后可以启动Apache。
