Difficulty getting Rails working on Ubuntu 14.04

I have a rails application that works fine on my local machine when I run

rails server

However I am having trouble getting it working on DO. The exact commands I have run are as follow

#create droplet with ubuntu and 1-click rails application
#open up server's console via ssh or online console

rm -rf /home/rails/*
apt-get install git
cd /home/rails
git init
git remote add origin MY_GIT_REPO
git pull origin master
#must add swapfile for bundle install to work
fallocate -l 512M /swapfile
chmod 600 /swapfile
mkswap /swapfile
swapon /swapfile
#make swapfile permanent
nano /etc/fstab # add this line to bottom of file --> /swapfile   none    swap    sw   0   0
#back to the rails stuff
bundle install
#switch from sqlite to mysql2, eventually (note I have not done this yet)
#need to add mysql2 to gemfile and edit config/database.yml using https://gist.github.com/erichurst/961978
bundle exec rake db:create db:schema:load db:seed
nano config/environments/production.rb # Set `config.assets.compile = true`
chown -R rails:www-data *
service unicorn restart
exec bundle rails s -d

After I run this it appears my IP is up and running (there’s no error shown), but my index page is not shown. Thanks for the help!
