Fix Nginx Port Conflict: Easy Solutions

When the port is occupied, you can try the following solutions:

1. Check the port occupancy status by using the command netstat -tuln to see which ports are currently in use on the system, as well as the names of the processes occupying those ports.
2. To kill the process occupying a port, use the kill command or kill -9 command to free up the port. For example, sudo kill -9 .
3. Change the port number in the Nginx configuration file: You can try changing the port number being listened to in the Nginx configuration file to a port number that is not already in use.
4. Restarting the Nginx service: After making changes to the Nginx configuration file, restart the Nginx service to apply the configuration. You can use the command sudo systemctl restart nginx to restart the Nginx service.
5. Check the firewall settings: The issue of ports not being accessible may be due to the system firewall. You can try disabling the firewall or modifying the firewall rules to allow port access.

The issue of Nginx startup port being occupied can usually be resolved through the above methods. If these methods are unsuccessful, it is recommended to further investigate other programs or services in the system to ensure the port is released before restarting Nginx.
