ruby-on-rails - 使用 Capistrano 部署 - 仅针对匹配的服务器运行

Question

我尝试使用 Capistrano 部署我的应用程序，但我收到此错误消息:

`deploy:setup' is only run for servers matching {:except=>{:no_release=>true}}, but no servers matched

运行此命令时:

bundle exec cap deploy:setup

这是我的 deploy.rb 文件。

set :application, "example.com"
set :repository, "git@github.com:username/repo.git"
set :use_sudo, false
set :scm, :git
set :web, application
set :app, application
set :db, application
set :branch, "master"
set :user, "webmaster"
set :deploy_to,  "/opt/www/#{application}"
set :deploy_via, :remote_cache
set :domain, application
set :port, 2222

set :bundler_cmd, "bundle install --deployment --without=development,test"
ssh_options[:paranoid] = false

namespace :deploy do
  task :start do ; end
  task :stop do ; end

  task :restart_stalker do
    run "cd #{deploy_to}/current && thor stalker:kill && stalker:init"
  end

  task :restart, :roles => :app, :except => { :no_release => true } do
    run "cd #{deploy_to}/current && touch tmp/restart.txt"
  end

  after "bundler_cmd", "deploy:restart_stalker"
end

我正在使用 Rails 3。

您需要定义一些角色。例如:

role :app, 'myapphostname'
role :web, 'mywebhostname'

您似乎使用了“set”而不是“role”，但您应该在进行更改之前确认这一点。
