ruby-on-rails – 使用瘦服务器部署Capistrano

编辑：配置文件现在位于/var/www/apps/current/thin.yml

...
  * executing "sudo -p 'sudo password: ' bundle exec thin start -C /var/www/thin.config.yml"
    servers: ["85.255.206.157"]
    [85.255.206.157] executing command

    command finished in 216ms
failed: "sh -c 'sudo -p '''sudo password: ''' bundle exec thin start -C /var/www/thin.config.yml'" on 85.255.206.157

仅复制了相关的最后一部分.整个文件等的复制工作正常.它只是启动似乎失败的集群.
这是我的deploy.rb文件,它处理所有Capistrano的东西：

编辑：该文件已被修改为以下内容：

require "bundler/capistrano"

# define the application and Version Control settings
set :application,"ESCO Matching Demo"
set :repository,"svn://192.168.33.70/RubyOnRails/ESCO"
set :deploy_via,:copy

# Set the login credentials for Capistrano
set :user,"kurt"

# Tell Capistrano where to deploy
set :deploy_to,"/var/www/apps"

# Tell Capistrano the servers it can play with
server "85.255.206.157",:app,:web,:db,:primary => true

# Generate an additional task to fire up the thin clusters
namespace :deploy do
  desc "Start the Thin processes"
  task :start do
    sudo "bundle exec thin start -C thin.yml"
  end

  desc "Stop the Thin processes"
  task :stop do
    sudo "bundle exec thin stop -C thin.yml"
  end

  desc "Restart the Thin processes"
  task :restart do
    sudo "bundle exec thin restart -C thin.yml"
  end

  desc "Create a symlink from the public/cvs folder to the shared/system/cvs folder"
  task :update_cv_assets,:except => {:no_release => true} do
    run "ln -s #{shared_path}/cvs #{latest_release}/public/cvs"
  end
end

# Define all the tasks that need to be running manually after Capistrano is finished.
after "deploy:finalize_update","deploy:update_cv_assets"
after "deploy","deploy:migrate"

编辑：这是我的thin.yml文件

编辑：
现在出现以下问题：

>我在最后一步从系统运行cap deploy命令时收到无法找到GemFile错误：启动服务器
>不执行迁移
>我似乎无法再手动启动集群.只有一个瘦实例正在启动.

更新：
这是我正在部署的服务器的gem env设置.通过使用cap shell然后运行命令获取此信息：

====================================================================
Welcome to the interactive Capistrano shell! This is an experimental
feature,and is liable to change in future releases. Type 'help' for
a summary of how to use the shell.
