Killing a System Process

Question

When I am trying to run Apache, it does not run. It tries to access the port 80 but port 80 is listening by a system process having PID 4.

How I can stop the "system" process?

Answer 1

Windows provides an excellent tool called Resource-Monitor (resmon.exe). On the network tab, it gives you a detailed view of what programs are listening on what ports on you computer. Just open that tool to find out the program currently listening on port-80 (whether its IIS or something else). Then all you have to do is end that process and remove it from your startup in case it is sitting there.

Answer 2

Port 80 is by default used by IIS. If you are running IIS on your machine, then you can stop it as explained here .

Answer 3

Skype也使用端口80，因此您可以关闭Skype并重新加载apache服务器。
