CHECK PASSENGER RUBY PATH

-

When we want to use the passenger with Nginx or Apache. Then we need to find the passenger ruby path.

So, we can easily find the ruby path using :-

passenger-config --ruby-command
When we run then we will get like :-
  Command: /home/rohit/.rvm/gems/ruby-2.1.10/wrappers/ruby
  Version: ruby 2.1.10p492 (2016-04-01 revision 54464) [x86_64-linux]
  To use in Apache: PassengerRuby /home/rohit/.rvm/gems/ruby-2.1.10/wrappers/ruby
  To use in Nginx : passenger_ruby /home/rohit/.rvm/gems/ruby-2.1.10/wrappers/ruby
  To use with Standalone: /home/rohit/.rvm/gems/ruby-2.1.10/wrappers/ruby /usr/bin/passenger start

Add that line in passenger.conf file
