Could you try very simple config with small application from passenger
distro, i.e. something like this.
http {
include mime.types;
default_type application/octet-stream;
passenger_root /usr/local/rvm/gems/ruby-1.9.2-p136/gems/passenger-3.0.9;
passenger_ruby /usr/local/rvm/wrappers/ruby-1.9.2-p136/ruby;
passenger_default_user www;
server {
listen 127.0.0.1:80;
server_name localhost;
root /usr/local/rvm/gems/ruby-1.9.2-p136/gems/passenger-3.0.9/test/stub/rack/public;
passenger_enabled on;
passenger_use_global_queue on;
}
}
After restart your nginx with passenger you should find nginx and passenger
processes.
% ps auxww | grep nginx | grep -v nginx
root 18932 4,0 15,9 44464 39656 ?? Ss 8:46 0:00,01 nginx: master process /usr/local/sbin/nginx
www 18933 4,0 16,0 44464 39904 ?? S 8:46 0:00,02 nginx: worker process (nginx)
% ps uaxww | grep -i passenger | grep -v grep

Does it possible reproduce your problem for simple configuration?
