I have removed, purged, dpkg purged, everything I can think of to get rid of an nginx somewhere on the server. I can't find it to get rid of it. all of the above say nginx is not installed. But the server is serving pages.
Earlier, I had done a purge to upgrade nginx to a dotdeb version (I'm on a Ubuntu server) and all my configuration files vanished with it. But the ghost server is serving the sites correctly according to the configuration that no longer exists as files in sites-enabled or sites-available.
I can't stop/start/restart/anything this rogue server, since it "doesn't exist".
"whereis" used to return /etc/nginx /usr/share/nginx and /usr/share/man/man1/nginx.1.gz - even while the uninstalls were showing nginx was not installed. I even deleted all three. The server is still serving files.
I'm at the point of believing in possession.
Someone please help. I need to get rid of this server and install another version (though it is good that it is keeping sites online till the mess can be fixed).
Anyone know how to exorcise this one?
