Question

我在我的Gemfile上使用了capistrano 3.2.1和以下gems：

  gem 'capistrano'
  gem 'capistrano-safe-deploy-to', '~> 1.1.1'
  gem 'capistrano-rvm'
  gem 'capistrano-unicorn-nginx', '~> 3.1.0'
  gem 'capistrano-rails', '~> 1.1'
  gem 'capistrano-bundler', '~> 1.1.2'

在Capfile上，我有以下内容：

require 'capistrano/setup'
require 'capistrano/deploy'

# Includes tasks from other gems included in your Gemfile
#
# For documentation on these, see for example:
#
#   https://github.com/capistrano/rvm
#   https://github.com/capistrano/rbenv
#   https://github.com/capistrano/chruby
#   https://github.com/capistrano/bundler
#   https://github.com/capistrano/rails
#

require 'capistrano/rvm'
require 'capistrano/bundler'
require 'capistrano/rails'
require 'capistrano/unicorn_nginx'
require 'capistrano/safe_deploy_to'
# require 'capistrano/secrets_yml'
# 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/*.rake').each { |r| import r }

在deploy.rb上，我有以下内容：

# config valid only for Capistrano 3.1
lock '3.2.1'

set :application, 'MyAoo'
# set :repo_url, 'MyRepoURL'

# Default branch is :master
# ask :branch, proc { `git rev-parse --abbrev-ref HEAD`.chomp }.call
# set :branch, 'master'

# Default deploy_to directory is /var/www/my_app
# set :deploy_to, 'project'

# No need to clone entire repo each time
# set :deploy_via, :remote_cache

# Default value for :scm is :git
# set :scm, :git

# Default value for :format is :pretty
# set :format, :pretty

# Default value for :log_level is :debug
# set :log_level, :info

# Default value for :pty is false
set :pty, true

# TODO check this
# set :forward_agent, true

# Sudo permissions not required
set :use_sudo, false

# Default value for :linked_files is []
# set :linked_files, %w{ config/database.yml }

# Default value for linked_dirs is []
# set :linked_dirs, %w{bin log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system}

# Default value for default_env is {}
# set :default_env, { path: "/opt/ruby/bin:$PATH" }

# Default value for keep_releases is 5
set :keep_releases, 3

# set :rvm_type, :user                     # Defaults to: :auto
# set :rvm_custom_path, '~/.myveryownrvm'  # only needed if not detected

# Set ruby version on the server.
set :rvm_ruby_version, '2.1.2'      # Defaults to: 'default'
set :rvm_roles, [:app, :web]

现在当我运行$ cap production safe_deploy_to时：确保在我当地我得到以下情况：

它仍然卡在那里，没有办法输入密码或提示中的任何内容。我无法理解为什么在我向部署者提供sudo权限时要求输入密码？

我错过了什么？

我是capistrano-safe-deploy-to插件的创建者。由于任务卡在此命令/usr/bin/env sudo mkdir -pv /var/www/myapp上，因此插件似乎存在问题。

我建议您使用deploy.rb中的删除（或已注释掉）选项重新运行capistrano命令：

set：pty，true
set：use_sudo，false

使用上述2个选项的默认值可以正常工作，无需覆盖它们。

如果您仍有问题，请打开capistrano-safe-deploy-to插件的问题，我会尽力提供帮助。

上限部署：检查卡住了
