如何在ROR部署中为git + capistrano 3配置远程引用？

我正在尝试使用capistrano(第一次)部署我的rails应用程序.首先要点,我正在使用:

红宝石1.9.3p362

Rails 3.2.13

rvm 1.24.7

Capistrano 3.0.1

Phusion Passenger 4.0.26

Ubuntu 12.04 LTS

尝试运行时出现以下错误 cap production deploy

DEBUG [679a47be]致命:没有远程配置列出引用.

我的完整cap production deploy输出包括在下面

   INFO [488ba755] Running /usr/bin/env mkdir -p /tmp/AppName/ on sub.example.com
    DEBUG [488ba755] Command: /usr/bin/env mkdir -p /tmp/AppName/

的Gemfile

# Deploy with Capistrano
gem 'capistrano',  '~> 3.0.0'
gem 'capistrano-rails', '~> 1.1.0'
gem 'rvm1-capistrano3', require: false

Capfile

# Load DSL and Setup Up Stages
require 'capistrano/setup'

# Includes default deployment tasks
require 'capistrano/deploy'

# require 'capistrano/rvm'
# require 'capistrano/rbenv'
# require 'capistrano/chruby'
require 'capistrano/bundler'
require 'capistrano/rails/assets'
require 'capistrano/rails/migrations'

# Loads custom tasks from `lib/capistrano/tasks' if you have any defined.
Dir.glob('lib/capistrano/tasks/*.cap').each { |r| import r }

deploy.rb

我已经改变了这个文件来添加我的git url,应用程序名称,deploy_to路径以及内部任务task :restart,以便重启Phusion Passenger.

set :application, 'AppName'
set :deploy_to, '/var/www/appname'

set :repository, "git@github.com:username/appname.git"  # Your clone URL
set :scm, "git"
set :user, "my-github-deploy-user"  # The server's user for deploys
set :scm_passphrase, "correct-password"  # The deploy user's password
set :branch, "master"
set :deploy_via, :remote_cache

# ask :branch, proc { `git rev-parse --abbrev-ref HEAD`.chomp }

set :ssh_options, {
   verbose: :debug
}

set :format, :pretty
set :log_level, :debug
# set :pty, true

set :linked_files, %w{config/database.yml}
set :linked_dirs, %w{bin log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system}

# set :default_env, { path: "/opt/ruby/bin:$PATH" }
# set :keep_releases, 5

namespace :deploy do

  desc 'Restart application'
  task :restart do
    on roles(:app), in: :sequence, wait: 5 do
      # Your restart mechanism here, for example:
      execute :touch, release_path.join('tmp/restart.txt')
      # 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
  end

  after :restart, :clear_cache do
    on roles(:web), in: :groups, limit: 3, wait: 10 do
      # Here we can do anything such as:
      within release_path do
        execute :rake, 'cache:clear'
      end
    end
  end
  after :finishing, 'deploy:cleanup'
end
