Question

我最近不得不对应用程序进行一些更新，这些应用程序在一年左右没有碰到过。当尝试使用Capistrano（通过Github）进行部署时，我收到此错误：

[deploy:update_code] exception while rolling back: IOError, closed stream

此处记录完整错误：https://gist.github.com/2829751

我在Github SSH安全恐慌后重新安装了服务器的SSH密钥。在远程服务器上什么都不应该改变，并且之前的部署工作正常。我本地系统唯一重大的变化就是转向RVM。

任何想法导致错误的原因是什么？

这是我的deploy.rb文件，如果有帮助：

default_run_options[:pty] = true 

set :domain, 'xxx.xxx.xxx'
set :repository,  "XXX MY REPO XXX"
set :branch, 'master'
set :password, 'XXXXXXX'

set :deploy_to, "/var/www/#{domain}"

set :scm, :git
set :repository_cache, "git_cache"
set :deploy_via, :remote_cache

ssh_options[:paranoid] = false

set :user, "XXX"
set :runner, user
set :use_sudo, true
set :rails_env, 'production'

role :app, domain # multiple domains can be added here for parallel deployment (i.e. test_app)
role :web, domain
role :db,  domain, :primary => true

namespace :deploy do
  task :start, :roles => :app do
    run "touch #{release_path}/tmp/restart.txt"
  end

  task :stop, :roles => :app do
    # Do nothing.
  end

  desc "Restart Application"
  task :restart, :roles => :app do
    run "touch #{release_path}/tmp/restart.txt"
  end
end

deploy.task :cold do
  deploy.update
  deploy.create_db
  deploy.migrate
  deploy.restart # Change to start if we're using mongrels
end 

after "deploy:update_code", :update_config
after "deploy:restart", "delayed_job:restart"
after "deploy", "deploy:cleanup"

#links config files from shared to the release path and mongrel path after deployment
desc "Create all symlinks and files needed for app activation ofter deployment"
task :update_config, :roles => :web do
    run "ln -s -f /var/www/#{domain}/shared/database.yml #{release_path}/config/database.yml"
    run "ln -s -f /var/www/#{domain}/shared/app.yml #{release_path}/config/app.yml"
    run "ln -s -f /var/www/#{domain}/shared/cache #{release_path}/public/cache"
    run "ln -s -f /var/www/#{domain}/shared/survey_cache #{release_path}/public/surveys"
    run "ln -s -f /var/www/#{domain}/shared/surveys #{release_path}/surveys"
end

desc "changes ownership to cbdsm:git"
task :update_permissions, :roles => :web do
    sudo "chown -R #{user}:git /var/www/#{domain}"
end

namespace :delayed_job do
  desc "Start the delayed_job process"
  task :start, :roles => :app do
      run "cd #{current_path} && RAILS_ENV=#{rails_env} script/delayed_job -n 3 start"
  end

  desc "Stop the delayed_job process"
  task :stop, :roles => :app do
      run "cd #{current_path} && RAILS_ENV=#{rails_env} script/delayed_job stop"
  end

  desc "Restart the delayed_job process"
  task :restart, :roles => :app do
      delayed_job.stop
      delayed_job.start
  end
end

更新：这似乎是一个问题set :use_sudo, true。删除该行和任何需要sudo的命令似乎解决了这个问题。我仍然不完全清楚改变了什么 - 这使得这条线成为问题。它之前运作良好。

此外，我删除了default_run_options[:pty] = true行。

如上所述：

这似乎是一个问题集：use_sudo，true。删除该行和任何需要sudo的命令似乎解决了这个问题。我仍然不完全清楚改变了什么 - 这使得这条线成为问题。它之前运作良好。

此外，我删除了default_run_options [：pty] = true行。

在这些情况下发布 /config/deploy.rb 会有所帮助......

顺便说一句，你如何设置:deploy_via设置？尝试将其更改为:remote_cache（来自:copy）：

set :deploy_via, :remote_cache

看看会发生什么。
