How to set up environment variables on Ubuntu 14, Nginx, Capistrano and Rails?

this is driving me crazy for a few days now and I can’t figure out how to solve this. I am new to this so it might just be something very simple.

I set up my VPS hosting on Ubuntu 14.04 using Digital Ocean to deploy my Rails 4 app to a production environment. I deployed my app using Capistrano and Nginx by following this tutorial https://www.digitalocean.com/community/tutorials/deploying-a-rails-app-on-ubuntu-14-04-with-capistrano-nginx-and-puma

The only problem that I currently have is that my environment variables are not loaded by my app. Or at least, when I try to subscribe to my newsletter, it tells me that a valid api key is required.

What I did so far:

• Installed rbenv-var as instructed in the documentation.
• Created a .rbenv-var file in my /appname/current folder
• When I run rbenv vars, everything looks OK
• ran source ~/.bash_profile (found this somewhere that could solve the problem, but it didnt)
• Tried “spring stop” as indicated somewhere but didn’t work either. Spring was not installed
• I also tried adding my variables to my ~/.bashrc file, that didn’t work either
• Tried adding them to my ~/.bash_profile file, ran source ~/.bash_profile but that didn’t work either.

This is my bash_profile file:

[[ -s "$HOME/.profile" ]] && source "$HOME/.profile" # Load the default .profile

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM$
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"
export MAILCHIMP_API_KEY="somenumber"
export MAILCHIMP_LIST_ID="somenumber"

Happy to add any extra code if required.

Thanks a lot!
