Nginx: [warn] conflicting server name "localhost" on 0.0.0.0:80, ignored

After modifying the Nginx configuration parameters, use Nginx-t to check the configuration.

After prompting Successfull, you can use nginx-s reload to reload the configuration

I encountered this problem in the configuration process, that is, after the host name is bound, a warning appears when reloading the configuration

" localhost " 0.0. 0.0:ignored

This means that server name is repeatedly bound, but this warning does not affect the server running. What's more, this duplicate binding means that the Nginx service is now running and duplicates in the new configuration that will be loaded, so this warning is actually unnecessary.
