Hi,

I’m using nginx with 1 php-fpm (via unix socket), and i’m wondering if  
there is a way to make nginx retry on error, something like  
fastcgi\_next\_upstream but for the same upstream.

I would like to be able to transparently restart php-fpm and not send  
some  
502 to the clients

So, is there a way to make nginx retry the same upstream for X seconds  
(or  
retry every Y seconds for max Z attempts or …) (on errors like  
“connect()  
failed (111: Connection refused) while connecting to upstream”) ?

I’m open to any tricks

Thanks in advance  
Etienne

p.s: I already know about atomic/transparent php deployment with  
“$realpath\_root” and multiple docroot (
