Why this shell won't work if it's called from rc.local but SSH?

问题

I made this shell script

/var/start-app.sh

#!/bin/sh
# file-name: app-start.sh
cd /var/www/html/app
bundle exec rake sunspot:solr:start RAILS_ENV=production
unicorn_rails -c config/unicorn.rb -E production -D

If I type /var/start-app.sh in SSH. It triggers, and everything works fine.

Then I did put sh /var/start-app.sh in the end line of /etc/rc.d/rc.local in order to make it run on Server's start up.

But this never work. Why? and How can I enable that?

From SSH, I called it with root permission. Is that why? If so, how can I give root permission to rc.local?

Looks like starting services from rc.local is not the best practice http://bencane.com/2011/12/30/when-its-ok-and-not-ok-to-use-rc-local/. You would be better writing an init script : http://refspecs.linuxbase.org/LSB_3.1.1/LSB-Core-generic/LSB-Core-generic/sysinit.html
