Deploying with Capistrano

1. sudo gem install capistrano-ext
2. cd yours_rails_directory
3. capify .
4. mkdir config/deploy

  
Now we will create two deployments staging and production and a new staging environment.

1. touch config/deploy/staging.rb
2. touch config/deploy/production.rb
3. touch config/environments/staging.rb

1. config/deploy.rb
2. config/deploy/production.rb
3. config/deploy/staging.rb
4. config/environments/staging.rb:  
5. config/databases.yml

Now run the capistrano commands to set up the deployment. 

1. cap staging deploy:setup
   (this creates the correct directory tree)
2. cap staging deploy:check
   (this checks to make sure setup ran)
3. cap staging deploy:update
   (this updates the server with the app code)
4. ssh your_user_name@your_deployment_server
   (fill in the correct user and server here)
5. cd your_deployment_directory/current
   (again fill in the correct deploy to dir)
6. RAILS_ENV=staging sudo rake gems:install
   (this installs gems that need native compiling)
7. RAILS_ENV=staging rake db:schema:load
   (loads the database)
8. RAILS_ENV=staging rake db:seed
   (loads any seed data)
9. script/console staging
   (load the console for testing)
10. app.get('/')
    (test to see if this returns ‘200’)
11. exit
    (exit the console)
12. exit
    (exit ssh)
13. cap staging deploy:restart
