帽部署：检查被卡住

Question

我使用Capistrano的3.2.1下面就我的Gemfile宝石：

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，我有以下几点：

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 } 

在部署.RB我有以下几点：

# 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$帽生产safe_deploy_to：保证我的地方，我得到了下面的情况：

它仍然卡在那里，没有办法将密码或任何东西放入提示。我无法理解为什么当我向部署者授予sudo特权时要求输入密码？

我错过了什么？

Answer 1

我是capistrano-safe-deploy-to插件的创建者。看起来这个插件有问题，因为任务被卡住在这个命令/usr/bin/env sudo mkdir -pv /var/www/myapp。

我可以建议重新运行Capistrano的命令删除（或注释掉）这些选项从deploy.rb：

• 集：PTY，真正
• 集：use_sudo，假

事情应该适用于上述2个选项的默认值，无需重写它们。

如果您仍然有问题，请为capistrano-safe-deploy-to插件打开问题，我会尽力提供帮助。
