机架错误：当我打开我的网页部署

Question

每次我我的本地机器cap:deploy上运行，我得到一个错误：

我解决这个问题的下一行：

$ bundle install --without development test 
$ bundle install --deployment 
$ service nginx restart 

但我真的很厌倦这样做一次又一次。有谁知道如何永久修复它？

我的Gemfile：

source 'http://rubygems.org' 

gem 'rails', '3.1.3'               
gem 'gravatar_image_tag' 
gem 'will_paginate' 
gem 'rack'                  
gem 'rake'                  
gem 'texticle', "2.0", :require => 'texticle/rails' 

# Gems used only for assets and not required 
# in production environments by default. 
group :assets do 
    gem 'sass-rails'                
    gem 'coffee-rails'               
    gem 'uglifier' 
end 

gem 'jquery-rails'

    gem 'capistrano' 
    gem 'rspec-rails'

    gem 'pg'                  
    gem 'annotate', :git => 'git://github.com/ctran/annotate_models.git'   
    gem 'faker'                 
end 

group :test do 
    gem 'rspec-rails'               
    gem 'webrat'                 
    gem 'spork' 
    gem 'autotest'

    gem 'autotest-fsevent'              
    gem 'autotest-growl'                          
    gem 'factory_girl_rails' 
end 

group :production do 
    gem 'pg'                  
    gem 'faker' 
end 

配置/ deploy.rb

set :user, "root"                 
set :rails_env, "production" 

default_run_options[:pty] = true

set :deploy_to, "/vol/www/apps/#{application}" 

set :scm, :git

server "my.ip", :app, 
          :web, 
          :db, :primary => true 


# 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 

我的服务器系统：

Ubuntu 10.04 LTS 
PostgreSQL 9.1 
Rails 3.1.3 
Ruby 1.9.3p27 
Nginx 1.0.11 (installed/compiled by passenger) 
Phusion passenger 3.0.11 
Capistrano 

Answer 1

capistrano不会自动运行除非你指定你在你的deploy.rb中使用了bundler。我将这一行添加到我的deploy.rb文件的顶部以激活捆绑器集成。 Capistrano随后会在部署时自动运行正确的bundler命令。

require 'bundler/capistrano' # Add Bundler integration to capistrano 

您的解决方案运行bundle install --without development test和bundle install --deployment的，实际上是相同的，但必须手动保持最新。另外，你可以将这个提炼成一个命令：bundle install --deployment --without development test。在您当前的解决方案中，您正在运行捆绑器两次。

Answer 2

我有同样的问题。在我们的5个环境中，我们的分期环境开始全力以赴。我无法找到原因，但我终于可以通过备份来部署，然后重新创建我们的部署目录，接着进行cap deploy：setup，cap deploy：cold then cap deploy
