端口端口80被NTkernelsystem占用

前段时间停止了Apa che结果在打开的时候发现无法打开 80端口被占用于是win+r运行cmd

输入net stat -ano

可以看到80端口被PID4占用于是打开任务管理器-进程-查看选择列勾选PID

可以看到p id 4的被NT kerne l& System占用

在网上找了很久找到解决方案

原文

翻译如下

该进程是H ttp. sys。它是http API的驱动组件 Http栈服务器。如果该端口被Http.sys占用说明一些正在使用ht tp. sys的应用程序在运行。这就是阻止Apach e运行的原因因为Htt p.sys占用着80端口。我们提供了一种应用程序的机制来帮助控制端口共享但是我需要调查导致你遇到这种困难的是什么特殊应用程序。如果你能提供给我们“netshhttp show servi cestate”这条命令的输出结果我就能找出是哪个应用程序在使用Http. sys。在你禁用H ttp. sys之前请按照下面的步骤来运行命令

1. scconfi ghttp stat = demand

2. reboo t

3. run the comma nd(netsh http show servi cestat)as admin istra tor

在你使用这个命令之前你可以按照下面步骤禁用http.sys

1. net stop http

2. Scconfi g http start=disab led

于是运行net stop http

按y确定

在运行Scconfi g http start=disab led

好了现在启动A pache可以启动了 。

在查看一下netst at -ano

发现pid 4占用了445端口

I work on Http.sys technology atMicrosoft and somebody sent me a l inkto this blog. I ama bitsurprised bythis behavioryou are seeing on Windows7 Beta and with some helpfrom you, I wi l l l ike to find out the root causeof this issue so thatwe can take theappropriate action if needed.

You are right,Http.sys uses port 80. It is the driver component for httpapi , the server httpstack(You can find more info on this technologyathttp://msdn.microsoft.com/en-us/l ibrary/aa364434(VS.85).aspx). In your case,someappl ication is running which is using http.sys to l isten on port80.This is preventingApache from using port80.We offera mechanism for appl ications to help control portsharing but I’ l l need to look into the specific appl ication that’s causing you this conflict. Ifyou can give us the output of fol lowing command“netsh http showservicestate”, then itwi l l al low me to find outwhich appl ication is using http.sys.Sinceyou have disabledhttp.sys, please fol lowthese steps l isted below before running the command:

1 .scconfig http start=demand

2.Re boot

3.Run the command(netsh http show servicestate)as administrator

After you have run this command,you can disable http.sys as fol lows:

1 . net stop http

2.Scconfig http start=disabled

Please let me knowif you face any issues in the process.
