Ruby on Rails server setup

Question

I'm trying to deploy ROR application to Ubuntu server(EC2). I'm using following versions:

• Ruby : 2.4.0p0
• Rails : 4.2.8
• Bundler : 1.17.3

*For some reason my colleague has created a gemset instead of normal setup.

gem env is:

I did the setup of nginx and passenger and set the root paths.

• nginx version: nginx/1.17.3
• Phusion Passenger : 6.0.4

I believe there is nothing wrong with nginx and passenger's settings but I'm getting following error: The Phusion Passenger application server tried to start the web application. But the application itself (and not Passenger) encountered an internal error.

Error details:

Does anybody has any idea?

Answer 1

passenger is trying to download a file that does not exist.

try with ruby 2.4.6 since that version is listed on the github release page

https://github.com/phusion/passenger/releases/

Answer 2

Most probably the point is in that you're setting up and testing rvm/ruby under ubuntu user, but nginx server is running under some other user (which does not have rvm configured, at least in the session in which the daemon runs)

RVM has ability to create a wrapper, that will set correct paths and gemset (if needed):

rvm alias create ruby_for_my_app ruby-2.4.0@myrepo

and then use /home/ubuntu/.rvm/wrappers/ruby_for_my_app/ruby in passenger_ruby nginx config directive (remember to reload it after changing)
