logs bind() to 0.0.0.0:80 failed (10013: An attempt was made to access a socket in a way forbidden by its access permissions)

It is found here that system occupies port 80, system is a system process, and cannot be closed. How can we solve it? I tested win7 and it works fine. How do you usually solve it?

Continue above, there is a problem with the configuration, test.conf copy a copy of nginx.conf, the configuration is as follows, why is it requesting www.hht.com (I have configured it in the host here), why is it still port 80, configuration The port inside is 32000,

What is the reason for this?

test.conf

#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;
