As shown in the figure:

View port occupancy:

View the processes that occupy the port:

Ps-ef | grep 3345

The result shows that port 80 is occupied by nginx itself, so you can kill the process and restart nginx.

Sudo kill-9 3345

Sudo netstat-apn | grep 80

After successfully killing the process, start nginx

Nginx is started successfully. Enter the ip address of the system where nginx is located in the browser to verify whether nginx is started successfully.

The following describes the start, stop and restart of nginx
