capistrano 2.15.5使って非railsアプリをサーバ上に配置してみた。
capistrano3でやってみた記事はこちら capistrano3.0で非railsを配置してみる - Qiita [キータ]

試してみた手順

$ bundle init
$ echo "gem 'capistrano', '~> 2.0'" >> Gemfile
$ echo "gem 'capistrano_colors'" >> Gemfile
$ echo "gem 'railsless-deploy'" >> Gemfile
$ bundle install --path vendor/bundle

$ bundle exec capify .
[add] writing './Capfile'
[add] making directory './config'
[add] writing './config/deploy.rb'
[done] capified!

config/deploy.rbを設定

set :application, "MyTips"
set :repository,  "https://github.com/mechamogera/MyTips"
set :scm, :git
set :keep_releases, 5

set :deploy_to, '/var/www/my_app'                                                                                     

default_run_options[:pty] = true
set :use_sudo, false

# No shared files
set :shared_children, %w()
# for No such file or directory Error
set :normalize_asset_timestamps, false

role :web, "[EC2のDNS名]"
set :user, 'ec2-user'
set :group, 'ec2-user'

before "deploy:setup" do
  run "sudo mkdir -p #{deploy_to}"
  run "sudo chown -R #{user}:#{group} #{deploy_to}"
end

# 念のためafterでも
after "deploy:setup" do
  run "sudo chown -R #{user}:#{group} #{deploy_to}"
end

EC2(AmazonLinux)を作成
capistrano実行

$ bundle exec cap deploy:setup
$ bundle exec cap deploy
$ bundle exec cap deploy:cleanup

EC2確認
