ruby-on-rails – capistrano从一个本地目录部署到另一个本地目录

我想在我的本地机器上部署应用程序.例如我的Rails APP在：
/ home / thesis / dev / myapp,但是我想要部署：安装到/ home / thesis / deploy /.我尝试过,但是capistrano尝试连接到本地主机,但根本不需要.我该如何解决？

这里是我的deploy.rb

role :app,"localhost"
role :web,"localhost"
role :db,"localhost",:primary => true

set(:deploy_to) { "/home/thesis/dev/myapp" }
set :bundle_without,[:development,:test]
set :use_sudo,false

set :repository,"."
set :scm,:none
set :deploy_via,:copy

set :copy_dir,"/home/thesis/deploy/tmp"
set :copy_remote_dir,"/home/thesis/deploy/tmp"

它与：

connection failed for: localhost (Errno::ECONNREFUSED: Connection refused - connect(2))

role :app,""

role :app,""

set :use_sudo,false
set :application,'thesis'     # you'll need to specify an app name
set :repository,:none
set :deploy_to,"/home/thesis/deploy/"   # the destination dir
set :deploy_via,:copy

# override deploy:restart since this isn't a Rails app
namespace :deploy do
  task :restart do
    # no-op
  end
end
