the ps info:
puppet 22573 1.0 0.0 140756 49276 ? S 11:00 0:01 Passenger AppPreloader: /etc/puppet/rack/allinone_02
I wanted to know why the Passenger AppPreloader start with puppet not root.
how can i change the own to root.

Answer 1

I figured it out , by adding the config below to config.ru
ARGV << "--rundir" << "/var/run/puppet"
now everything is ok
