I changed ruby version to 2.1.5 with RVM, configured 4 rails App with Apache, but I can't start them with Passenger. So I got this error everytime.
App 8612 stderr: Cannot execute "/root/.rvm/gems/ruby-2.1.5/gems/passenger-5.0.8/buildout/support-binaries/PassengerAgent": Permission denied (errno=13)

First of all, you should not run your application with the root user.
Add PassengerUserSwitching on to your virtual host. If your web app is owned by root, it should be able to use rvm (as it is installed for root user only).
