I get start-stop-daemon not found when trying to start nginx, howd you solve this on centos

sudo bash < <( curl -L http://bit.ly/rvm-install-system-wide ) should be curl -L https://get.rvm.io | bash -s stable --autolibs=enabled [--ruby] [--rails] [--trace]

I'm able to run the nginx, passenger on centos 6.4 perfectly fine. I'm also able to run this sample app
mkdir -p /var/www/racktest
mkdir /var/www/racktest/tmp
mkdir /var/www/racktest/public

vi /var/www/racktest/config.ru

app = proc do |env|
[200, { "Content-Type" => "text/html" }, ["hello world this is a test"]]
end
run app

---

Now when I create rails app
rails new todo
and point my public folder location to my nginx.conf root location, i'm getting a error page.
Some problem with config.ru i know , unable to figure out!

Help will be appreciated!

start-stop-daemon is not available on centOS by default. Try a different init.d/nginx script. This is a good one: https://github.com/useruby/rails-nginx-passenger-centos/blob/master/nginx/nginx
