I'm using uwsgi to run my cherrypy websites behind nginx and i'm using the following location config settings...
location / {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header X-Originating-IP $remote_addr;
proxy_set_header HTTP_REMOTE_ADDR $remote_addr;
proxy_set_header REMOTE_ADDR $remote_addr;
proxy_set_header CLIENT_IP $remote_addr;
proxy_pass http://0.0.0.0:8080/;
}
Hope this helps!
