Nginx Display Discuz page

I don't know if my topic is right. I have just learned.

Install Nginx display Discuz interface. I watched the video several times and found no problem. Is the error code that always appears 502

I went back a few times. Feel the need to pay attention to the points:

1, turn off Nginx default virtual host Deny all;

2, in this machine fill in the hosts configuration;

3, note the socket port configuration in Nginx virtual host.

4,/usr/local/php/etc/php-fpm.conf in the configuration, restart. Note the error that occurred.

There is also the Discuz path in the virtual host must be written to.

I examined the problems and went in.
