hi guys,

Assuming I made some changes to the source code.  
My production environment runs on passenger and nginx.

How do I restart passenger and nginx with minimal downtime?

Surely I can’t do a “w” on the terminal because a server will not  
always be in zero load.

Would love to hear some recommendations.

PS- I have read on unicorn ([Unicorn! - The GitHub Blog](http://github.com/blog/517-unicorn)) but  
would love to hear what we can do for passenger.

thanks

i think i found something.  
Just send a SIGHUP signal to the nginx process via kill.  
Seems to work well.  
Anyone got a better idea? 🙂

thanks

Yep, use: $ kill -HUP \<nginx\_pid\>
