How can I change php-fpm.conf (or php.ini) so all errors/ warnings/ ... are written to stderr (or alternatively to stdout)?
I run php5-fpm with daemonize = no and want to see all errors in my terminal.
The solution is to set ...
; Redirect worker stdout and stderr into main error log. If not set, stdout and
; stderr will be redirected to /dev/null according to FastCGI specs.
; Note: on highloaded environement, this can cause some delay in the page
; process time (several ms).
; Default Value: no
catch_workers_output = yes
