上限部署通过 sftp 上传失败

Question

美好的一天！我会尽量具体说明这一点。很抱歉，我在尝试部署我的应用程序时遇到了很多麻烦。我对 Rails 完全陌生，所以我遵循了使用 Rails 第 4 版进行敏捷 Web 开发，我被困在使用 capistrano 部署的部分我已经尝试了书中的确切代码，没有工作，并采取了一些来自这个论坛和其他论坛的建议被证明是有帮助的，但我仍然无法正确部署我的 deploy.rb 是这样的：

require 'bundler/capistrano'

set :user, 'user_created_for_this_example'

set :domain,  'IPADDRESS'

set :application, 'depot'

# file paths

set :repository,  "#{user}@#{domain}:depot.git"

set :deploy_to, "/home/#{user}/#{domain}"

# set :scm, :git # You can set :scm explicitly or Capistrano will make an intelligent guess 
based on known version control directory names

# Or: `accurev`, `bzr`, `cvs`, `darcs`, `git`, `mercurial`, `perforce`, `subversion` or `none`

#roles server

role :web, domain

role :app, domain

role :db, domain, :primary => true

#deploy config

set :deploy_to, "/home/#{user}/#{domain}"

set :deploy_via, :copy

set :scm, 'git'

set :branch, 'master'

set :scm_verbose, true

set :use_sudo, false 


# if you want to clean up old releases on each deploy uncomment this:
# after "deploy:restart", "deploy:cleanup"

# if you're still using the script/reaper helper you will need
# these http://github.com/rails/irs_process_scripts

# If you are using Passenger mod_rails uncomment this:

namespace :deploy do

  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

after "deploy:update_code", :bundle_install

desc "install the necesary prerequisites"

task :bundle_install, :roles => :app do

  run "cd #{release_path} && bundle install"

end

当我运行 cap deploy:setup 和 cap deploy:check all 似乎工作正常：

~/rails_projects/depot$ cap deploy:setup

  * 2012-11-13 10:37:35 executing `deploy:setup'

  * executing "mkdir -p /home/git/xx.xx.xx.xx /home/git/xx.xx.xx.xx/releases /home/git

You appear to have all necessary dependencies installed

但是当 cap deploy:migrations、cap deploy 或 cap deploy:cold 命令出现时会弹出下一个：

~/rails_projects/depot$ cap deploy:migrations

很抱歉，如果这是一些虚拟问题、易于修复的问题或已经发布的问题，但我不知道还能尝试什么，再次，我只是从这些东西开始，我真的迷路了.我在同一台机器上运行所有东西，所有 xx.xx.xx.xx 代表我的 IP 地址。任何建议将不胜感激。我试图尽可能具体，但如果缺少某些内容，我会发布它。预先感谢您的时间和帮助。

Answer 1

您的问题是您的 sftp 源和目标位置相同：

** sftp upload /tmp/20121113173743.tar.gz -> /tmp/20121113173743.tar.gz

为了解决这个问题，您可以在 config/deploy.rb 文件中指定参数 copy_dir，如下所示：

set :copy_dir, "/tmp/sftp"

那时不需要手动创建该文件夹。

Answer 2

尝试将此行添加到您的 deploy.rb 配置文件中：

default_run_options[:pty] = true

Answer 3

我们将 Capfile 更改为

set :deploy_via, :copy

到

set :deploy_via, :remote_cache

这对我们有用。我们没有添加以下行

default_run_options[:pty] = true
