当尝试打开Apache时遇到'Port 80 in use by “Unable to open process” with PID 4!'错误，这表明端口80已被占用。解决方案包括更改Apache的监听端口，如改为8081，或者关闭占用该端口的服务——WorldWideWebPublishingService。在Windows中，可以通过服务管理器（services.msc）找到并停止该服务。

打开apache的时候出现这个错误：Port 80 in use by “Unable to open process” with PID 4!

错误原因：端口80被占用

解决方法1：
更改apache的端口，通常8081或81之类的都可以。

解决方法2：
关闭PID4，即 World Wide Web Publishing Service 服务，windows + R，输入services.msc，找到这个服务，关闭即可。

确定要放弃本次机会？

一、问题描述：启用接口服务调试的时候，报错。二、解决方案：右键服务相关项目主目录，选择【属性】方案一：如图所示，将选项改为【Local IIS】方案二：修改端口！！！注意：端口默认是“80”，如果改成其他的，在服务地址前面就得加上相关端口，所以综上方案一更实用。如果这篇博客对您有所帮助的话，将是我的荣幸，如果能够再点个赞的话，将是多么美好的一件事。???? ...
