I am using Nginx 1.8.0 on Ubuntu 12.04 with multiples domains, right now all my websites are online and working but I would like to change the port and others things in the conf of each domain (inside /etc/nginx/sites-available/domane).
The strange thing is : If i stop nginx : the wesbites are offline, which is normal. If i have a syntax error in some conf file : nginx warn me and wont restart, which is normal too.
But every changes i make doesnt seem to apply, like I can change the listen port to 1234 (or whatever), reload/restart nginx, the website still online. I can remove the domain in sites-enabled, reload/restart nginx, the website still online.
I use nginx for more than 5 years and its the first time I see that. Is there any cache or something new in the nginx configuration that i could have missed ?
