nginx supports the following signals :

TERM, INT - Quick shutdown
QUIT - Graceful shutdown
HUP - Configuration reload: Start the new worker processes with a new configuration, Gracefully shutdown the old worker processes
USR1 - Reopen the log files
USR2 - Upgrade Executable on the fly
WINCH - Gracefully shutdown the worker processes

HUP is what you are looking for, so sudo kill -HUP pid (nginx pid)

Usually nginx's init-script has reload action, i.e:

Linux /etc/init.d/nginx reload
FreeBSD /usr/local/etc/rc.d/nginx reload

`USR2` is for upgrading the executable, not for simple config reloading. – Brad May 22 '14 at 21:19
