Capistrano无法部署到远程服务器

解

解决方案是将以下内容添加到production.rb：

的顶部 
$:.unshift(File.expand_path('./lib', ENV['rvm_path'])) # Add RVM's lib directory to the load path.
require "rvm/capistrano"                  # Load RVM's capistrano plugin.
set :rvm_ruby_string, '1.9.2@rails31dataserver'        # Or whatever env you want it to run in.
set :rvm_bin_path, '/usr/local/rvm/bin'

我之前缺少的部分是set :rvm_bin_path, '/usr/local/rvm/bin'，因为之前我从未在Capistrano部署中使用过该配置设置，而且我已经做了一些。哦，好吧，一天都在工作。信用转到irc.freenode.net上的#rvm频道的tonyflint！

悬崖笔记

  • 我正在运行RVM的系统安装
  • 我正在通过Capistrano部署

我目前傻眼了。基本上正在发生的事情是我正在尝试通过Capistrano进行部署，而且它很难，很难。这是我的deploy.rb和production.rb文件的贴图（我正在做一个多阶段环境并省略staging.rb文件，因为它工作正常）。 http://pastie.org/2523675

以下是cap production deploy:setup的输出：

$ cap production deploy:setup
  * executing `production'
    triggering start callbacks for `deploy:setup'
  * executing `multistage:ensure'
  * executing `deploy:setup'
  * executing "sudo -p 'sudo password: ' mkdir -p /var/www/html/dataserver /var/www/html/dataserver/releases /var/www/html/dataserver/shared /var/www/html/dataserver/shared/system /var/www/html/dataserver/shared/log /var/www/html/dataserver/shared/pids"
    servers: ["omitted"]
Password:

现在，我知道为什么会这样。我正在远程尝试使用sudo，这是一个安全禁忌。所以，这意味着我需要使用default_run_options[:pty] = true。所以我取消注释它并再次运行cap production deploy:setup并且所有运行都很好并且花花公子。部署的目录结构获取设置和所有内容。真棒。现在我尝试运行cap production deploy，这是输出：

所以看来无论加载什么环境都看不到rake。要查看我创建部署任务的路径中加载的内容，请输出：

$ cap production test_path
  * executing `production'
    triggering start callbacks for `test_path'
  * executing `multistage:ensure'
  * executing `test_path'
  * executing "echo $PATH"
    servers: ["omitted"]

  * executing "echo $rvm_path"
    servers: ["omitted"]
    [omitted] executing command
 ** [out :: omitted] 
    command finished in 5ms

现在你会注意到路径绝对不正确。对于正在建立会话的用户，应该如下：

/usr/local/rvm/gems/ruby-1.9.2-p290@rails31dataserver/bin:/usr/local/rvm/gems/ruby-1.9.2-p290@global/bin:/usr/local/rvm/rubies/ruby-1.9.2-p290/bin:/usr/local/rvm/bin:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/home/lpeabody/bin

而且，我知道为什么这不起作用。这是因为我正在运行default_run_options[:pty] = true我的环境正在加载，至少这是我目前的理论。所以，毕竟，我得出结论 - 我需要以某种方式加载我的环境，以便rake可以在不启用远程sudo的情况下运行。

现在，我知道我不是唯一需要这样做的人，所以任何指针或提示都会非常感激。我现在已经把我的大脑放在了8个小时的大部分时间里，我需要尽快部署这个应用程序。

解决方案是将以下内容添加到production.rb：

的顶部 
$:.unshift(File.expand_path('./lib', ENV['rvm_path'])) # Add RVM's lib directory to the load path.
require "rvm/capistrano"                  # Load RVM's capistrano plugin.
set :rvm_ruby_string, '1.9.2@rails31dataserver'        # Or whatever env you want it to run in.
set :rvm_bin_path, '/usr/local/rvm/bin'

我之前缺少的部分是set :rvm_bin_path, '/usr/local/rvm/bin'，因为之前我从未在Capistrano部署中使用过该配置设置，而且我已经做了一些。哦，好吧，一天都在工作。信用转到irc.freenode.net上的#rvm频道的tonyflint！

确保你跑：

gem install rvm-capistrano

之前

require "rvm/capistrano" in your "deploy.rb"

我这样做之后就行了。

答案 2 :(得分：1)

在capfile中尝试一些事情（这些是用于系统范围的RVM安装，不适用于每用户安装。）

require "rvm/capistrano"
set :rvm_bin_path, "/usr/local/rvm/bin"
$:.unshift(File.expand_path('./lib', ENV['rvm_path'])) # Add RVM's lib directory to the load path.

答案 3 :(得分：0)

就我而言，添加

default_run_options[:pty] = true

解决了这个问题。
