How to correctly restart nginx?

[Max]

Hi,

I find "reload" can get the job done.

But if I wantt o enable #gzip  on; , I still need to reboot the server after
I changed the conf file (I am not 100% sure about this, but all my stuffs
working after I reboot the server, I can't just use "reload" comand to get
it works").

At first, I just think the restart process is just like apache, but nginx
really does it better. You can archive zero downtime time if you restart it
correctly :-).
