XAMPP Port 80 in use by "Unable to open process" with PID 4
提问by Dave Cribbs
XAMPP won't work it says
XAMPP 不起作用，它说
Port 80 in use by "Unable to open process" with PID 4!
6:32:24 PM [Apache] Apache WILL NOT start without the configured ports free!
6:32:24 PM [Apache] You need to uninstall/disable/reconfigure the blocking application
6:32:24 PM [Apache] or reconfigure Apache and the Control Panel to listen on a different port
I have tried everything from deleting the World Wide Web Publishing Service (which did not work because i dont even have it installed.) To using the command prompt which says
我已经尝试了从删除万维网发布服务（这没有用，因为我什至没有安装它）到使用命令提示符的所有方法

Simply set Apache to listen on a different port. This can be done by clicking on the "Config" button on the same line as the "Apache" module, select the "httpd.conf" file in the dropdown, then change the "Listen 80" line to "Listen 8080". Save the file and close it.
只需将 Apache 设置为侦听不同的端口。这可以通过单击“Apache”模块所在行上的“Config”按钮，在下拉列表中选择“httpd.conf”文件，然后将“Listen 80”行更改为“Listen 8080”来完成。保存文件并关闭它。
Now it avoids Port 80 and uses Port 8080 instead without issue. The only additional thing you need to do is make sure to put localhost:8080 in the browser so the browser knows to look on Port 8080. Otherwise it defaults to Port 80 and won't find your local site.
现在它避免了端口 80 并使用端口 8080 而没有问题。您需要做的唯一额外的事情是确保将 localhost:8080 放入浏览器，以便浏览器知道查看端口 8080。否则它默认为端口 80，不会找到您的本地站点。

So I have faced the same problem when trying to start apache service and I would like to share my solutions with you. Here is some notes about services or programs that may use port 80:
所以我在尝试启动 apache 服务时遇到了同样的问题，我想与您分享我的解决方案。以下是有关可能使用端口 80 的服务或程序的一些注意事项：
- Skype: skype uses port 80/443 by default. You can change this from tools->options-> advanced->connections and disable checkbox "use port 80 and 443 for addtional incoming connections".
- IIS: IIS uses port 80 be default so you need to shut down it. You can use the following two commands net stop w3svc net stop iisadmin
- SQL Server Reporting Service: You need to stop this service because it may take port 80 if IIS is not running. Go to local services and stop it.
- Skype：Skype 默认使用端口 80/443。您可以从工具-> 选项-> 高级-> 连接更改此设置并禁用复选框“使用端口 80 和 443 进行附加传入连接”。
- IIS: IIS 默认使用端口 80，因此您需要关闭它。可以使用以下两个命令 net stop w3svc net stop iisadmin
- SQL Server Reporting Service：您需要停止此服务，因为如果 IIS 未运行，它可能会占用端口 80。转到本地服务并停止它。
These options work great with me and I can start apache service without errors.
这些选项对我来说很好用，我可以毫无错误地启动 apache 服务。
The other option is to change apache listen port from httpd.confand set another port number.
另一个选项是从httpd.conf更改 apache 监听端口并设置另一个端口号。
Hope this solution helps anyone who face the same problem again.
希望这个解决方案可以帮助任何再次面临同样问题的人。

Your port 80 is being used by the system.
系统正在使用您的端口 80。
- In Windows “World Wide Publishing" Service is using this port and it's process is system which PID is 4 maximum time and stopping this service(“World Wide Publishing") will free the port 80 and you can connect Apache using this port. To stop the service go to the “Task manager –> Services tab”, right click the “World Wide Publishing Service” and stop.
- If you don't find there then Then go to "Run > services.msc" and again find there and right click the “World Wide Publishing Service” and stop.
- If you didn't find “World Wide Publishing Service” there then go to "Run>>resmon.exe>> Network Tab>>Listening Ports" and see which process is using port 80
- 在 Windows 中，“World Wide Publishing”服务正在使用此端口，它的进程是 PID 最大时间为 4 的系统，停止此服务（“World Wide Publishing”）将释放端口 80，您可以使用此端口连接 Apache。要停止该服务，请转到“任务管理器 -> 服务选项卡”，右键单击“全球发布服务”并停止。
- 如果你没有找到那么然后去“运行> services.msc”并再次找到那里并右键单击“World Wide Publishing Service”并停止。
- 如果您没有找到“World Wide Publishing Service”，则转到“运行>>resmon.exe>>网络选项卡>>侦听端口”并查看哪个进程正在使用端口80
And from "Overview>>CPU" just Right click on that process and click "End Process Tree". If that process is system that might be a critical issue.
从“概览>>CPU”中右键单击该进程并单击“结束进程树”。如果该过程是系统，则可能是一个关键问题。

I had the following error message Port 80 in use by "Unable to open process" with PID 4! Apache WILL NOT start without the configured ports free! You need to uninstall/disable/reconfigure the blocking application or reconfigure Apache and the Control Panel to listen on a different port Starting Check-Timer Control Panel Ready
我有以下错误消息端口 80 正在被“无法打开进程”与 PID 4 使用！如果配置的端口没有空闲，Apache 将不会启动！您需要卸载/禁用/重新配置阻止应用程序或重新配置 Apache 和控制面板以侦听不同的端口 启动检查计时器控制面板就绪
opened the httpd.conf and changed the listen port from 80 to 1234 in both places
打开httpd.conf，把两个地方的监听端口从80改为1234
Listen 12.34.56.78:1234
听 12.34.56.78:1234
Listen 1234
听 1234
Then go to Config for the xampp control panel and go to service and port setting and changed the port from 80 to 1234
然后转到xampp控制面板的配置并转到服务和端口设置并将端口从80更改为1234
That worked.
那奏效了。
