Deploy Ruby on Rails project on EC2 - ruby-on-rails

Question

I have setup everything and i am able to connect to the server via ssh on a free tier
now my project is how can i upload the server files and database?
I see that there are some gems in rails such as rubber that deploy the files to a server but how can i also integrate git so i can commit changes as well?

Answer 1

Code
For uploading the files, check out capistrano. Another popular tool is Vlad the deployer.
Here's a simple deploy.rb for a rails3 app (assuming passenger) that only needs one server right now (replace all the with actual values):
require 'bundler/capistrano'
require 'capistrano_colors'
set :application, "<APP_NAME>"
set :repository, "git#github.com:<USER>/<PROJECT>.git"
set :branch, "master"
set :deploy_to, "/home/<DEPLOY_USER>/<APP_NAME>"
set :keep_releases, 3
set :scm, :git
set :user, "<DEPLOY_USER>"
set :use_sudo, false
set :deploy_via, :remote_cache
default_run_options[:pty] = true
default_run_options[:shell] = '/bin/bash -l'
ssh_options[:forward_agent] = true
role :web, "<IP_OR_PUBLIC_DNS>"
role :app, "<IP_OR_PUBLIC_DNS>"
namespace :deploy do
task :start do ; end
task :stop do ; end
task :restart, :roles => :app, :except => { :no_release => true } do
run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}"
end
end
after "deploy", "deploy:cleanup"
Note: you should ssh-add the private keys for the deploy user as well as the key you use for github before running cap deploy. (e.g. ssh-add ~/.ssh/id_dsa)
Database
In terms of the database, you can run migrations as part of a deploy via cap deploy:migrations, or independently via cap deploy:migrate. Just be sure to list a server with role :db
role :db, "<IP_OR_PUBLIC_DNS>", :primary => true
(Note: this is the server that will be used to run the migrations, not the actual db. The db should be specified in your database.yml).
Setting up the database itself is beyond the scope of this answer, but you can either run a db directly on the instance, or take a look at Amazon's RDS, which is really simple to set up and more stable than a db running on a single instance.
