Nginx port occupancy, start error: Bind () to 0.0.0.0:80 failed (10013:an attempt is made to access a socket in a-a-type F

I need to configure the project to use Nginx, and nginx is not up, I looked at Nginx in the Logs folder Error.log error log, found that the error message is:

2017/04/20 16:00:52 [Emerg] 4276#4280:bind () to 0.0.0.0:80 failed (10013:an attempt is made to access a socket in a The forbidden by its access permissions)

It is known from the Scarlet Letter section that the 80 port is occupied, causing Nginx to fail to boot.

Solutions

1 Press the keyboard win+r to open the Run interface, enter cmd, OK, open the Administrator interface

2 input Netstat-aon | findstr:80

Look for port occupancy, find out which port number 0.0.0.0:80, my Apache2.2 (used in the previous configuration of the PHP development environment) occupied, after viewing, the PID value is 4300

3 input Tasklist|findstr "4300"

Find the service name for Port 4300, Httpd.exe, this is apache2.2. If you do not know which file, Baidu can find the corresponding service name.

4 then stop the service in the computer service, remove the occupation

5 when the corresponding service is stopped, Nginx will start normally.

6 other port-occupied issues can also be resolved in this way.
