Capistrano部署错误

Question

我最近不得不对某个应用程序进行一些更新，而这些应用程序大约一年没有涉及。当尝试用Capistrano的（通过Github上）部署，我得到这个错误：

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

全部记录在这里的错误：https://gist.github.com/2829751

我重新安装了SSH Github上安全恐慌后，我的服务器的SSH密钥。远程服务器上的任何内容都不应该改变，并且之前部署工作正常。我本地系统唯一重要的变化就是转向RVM。

任何想法是什么导致了错误？

这是我的deploy.rb文件，如果这能帮助：

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 

UPDATE：这似乎是一个问题set :use_sudo, true。删除该行和任何需要sudo的命令似乎可以解决问题。我还没有完全清楚什么改变了 - 这使得这条线有问题。它以前工作得很好。

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

张贴以上：

这似乎是一个问题集：use_sudo，真实。删除该行和任何需要sudo的命令似乎可以解决问题。我还没有完全清楚什么改变了 - 这使得这条线有问题。它以前工作得很好。

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

在这些情况下发布/config/deploy.rb将有助于...

顺便说一句，你怎么设置:deploy_via设置？尝试改变这:remote_cache（从:copy）：

set :deploy_via, :remote_cache 

，看看会发生什么。
