Today, I would like to share with you how to solve the problem that port 80 of windows is occupied and nginx cannot be started. The content is detailed and the logic is clear. I believe most people still know too much about this, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

1. Installation

Download the latest version used under windows, which is currently 1.11.10, as shown in the figure:

Just download it and decompress it.

2. Run

Run nginx and report an error:

[emerg] 10348: 10940: bind () to 0.0.0.0 failed 80 failed (10013: an attempt was made to access a socket in a way forbidden by its access permissions)

As shown in the figure:

You can also see it in the log log, open:

Nginx-1.11.10\ logs\ error.log

As shown in the figure:

Nginx uses port 80 by default, but port 80 under windows is occupied. Check:

Occupied by a process with a pid of 4, check:

It's a system process, take a look in the task manager:

Sure enough.

3. Problem solving

The solution is to make the system process no longer occupy port 80 and need to modify the registry.

3.1 Open the registry

Enter regedit in the launch bar

3.2 find the registration key and modify it

find

Hkey_local_machine\ system\ currentcontrolset\ services\ http

There is an entry of type reg_dword start registry key:

The original value is 3:

Change to 0:

3.3 restart the operating system

Restart the windows system, and the original system process will not occupy port 80.

4. Rerun nginx

Run under the installation directory of nginx:

Start nginx.exe

Or:

Nginx.exe

As shown in the figure:

In the task manager, you can see that two processes will be started in the background:

5. Close nginx

Nginx.exe-s stop

Or:

Nginx.exe-s quit

Stop can quickly stop nginx, but may not save the relevant information; while quit stops the nginx in a complete and orderly manner, the process saves the relevant information.
