nginx 404 jumps to a custom page

1. Write an error.html page yourself

2. Change nginx.conf and add in http definition area: fastcgi_intercept_errors on;

3. Change nginx.conf and add in the server area: error_page 404 /404.html 

4. Restart ngnix

In addition, if there is an error page on port 8000, it should also jump to the error page on port 80.

Add error_page 404 error under server 8000, and include error.conf

# the difference when adding URI to proxy_pass directive:

# why I use variable but not staticlly config the url:

# and resolver is needed, or will get 502, ref:
