Question

这是我第一次将rails应用程序部署到服务器。它在本地工作得非常好，但是当我试图将它移动到服务器进行生产时，它并没有显示出来。我得到的只是显示我的项目文件夹的图像。我需要做出任何改变吗？

以下是我已经完成的更改 - database.yml - ＆gt;生产改变了环境

我为此目的使用过phusion乘客和apache。任何遇到类似情况的人，请帮帮我。任何帮助将受到高度赞赏。在此先感谢：）

我尝试运行的服务器还有在ruby 1.8.7上运行的项目;当我的项目使用另一个项目的gemsets时有2个实例。所以不得不使用.rvmrc（我知道现在已弃用）将它指向我应用应该使用的正确gemset。

配置：

<VirtualHost *:80>
  ServerName cloudapp.net
  DocumentRoot /var/www/test1/public
  <Directory /var/www/test1/public>
    Allow from all
    Options -MultiViews
  </Directory>
</VirtualHost>

乘客配置：

LoadModule passenger_module /usr/local/rvm/gems/ruby-1.9.3-p448/gems/passenger-4.0.20/buildout/apache2/mod_passenger.so
PassengerRoot /usr/local/rvm/gems/ruby-1.9.3-p448/gems/passenger-4.0.20
PassengerDefaultRuby /usr/local/rvm/wrappers/ruby-1.9.3-p448/ruby

您是否遵循了每一步？

cap deploy:setup

cap deploy:cold

你创建了符号链接吗？我将在这里发布我的文件的工作演示..

我的deploy.rb

  task :precompile_application do

  end

end

Answer 2

您的乘客配置看起来不错。

您的PassengerDefaultRuby指向1.9.3-p448。是什么让你相信它正在使用1.9.3-p225？

由于您使用RVM，请运行这些命令为您的乘客找到正确的红宝石路径

rvm use 1.9.3
passenger-config --ruby-command

然后使用命令的输出并在VirtualHost块中添加此行以强制您的应用程序使用特定版本的ruby。

PassengerRuby /path/to/ruby/1.9.3/

注意：这是您已定义的PassengerDefaultRuby的补充。 (See Documentation for PassengerRuby)

运行此命令以检查文件夹权限

passenger-config --root
