在nginx上部署多个Ruby on Rails应用程序

Question

我有两个RoR应用程序，一个是使用ruby 2.0.0，名为dataentry3的gemset（rvm使用2.0.0@dataentry3），第二个应用程序使用ruby 1.9.3 @ V1。

我试图部署方式如下这些应用程序：

1. rvm use ruby-2.0.0@dataentry3
2. cd dir/app1
3. gem install passenger
4. passenger-install-nginx-module

5. 编辑nginx.conf：

   http { 
   passenger_root /usr/local/rvm/gems/ruby-2.0.0-p195@dataentry3/gems/passenger-4.0.3; 
   
   server { 
       listen  80; 
       server_name localhost; 
       location/{ 
        passenger_ruby /usr/local/rvm/wrappers/ruby-2.0.0-p195@dataentry3/ruby; 
        root /var/www/adgally/dataentry4/public; 
        passenger_enabled on; 
       } 
   } 
   
   } 
   

6. 一切工作正常（http://my-ip）。

完成这些步骤之后我试图部署上的地址http://my-ip/v1秒应用程序（新PHUSION乘客允许运行多个Ruby版本，see here）

步骤我做：

1. rvm use ruby-1.9.3@v1
2. cd dir/app2
3. gem install passenger

4. 编辑nginx.conf：

   http { 
   passenger_root /usr/local/rvm/gems/ruby-2.0.0-p195@dataentry3/gems/passenger-4.0.3; 
   
   server { 
       listen  80; 
       server_name localhost; 
       location/{ 
        passenger_ruby /usr/local/rvm/wrappers/ruby-2.0.0-p195@dataentry3/ruby; 
        root /var/www/adgally/dataentry4/public; 
        passenger_enabled on; 
       } 
   location /v1 { 
       passenger_ruby /usr/local/rvm/wrappers/ruby-1.9.3-p429@v1/ruby; 
       root /var/www/adgally/v1/public; 
       passenger_enabled on; 
   } 
   } 
   
   } 
   

在此之后，第二应用（http://my-ip/v1）不工作。我收到提示：

必须有红宝石2.0.0和Ruby-1.9.3乘客宝石之间的冲突。我不明白为什么，因为新版本的乘客是支持这一点的。在passenger_root指令更改为/usr/local/rvm/gems/ruby-1.9.3-p429@v1/gems/passenger-4.0.3后第二个应用程序开始工作，但第一个不是（几乎相同的错误日志）。

Answer 1

您宽设置红宝石版本的系统与rvm use...

您需要使用PassengerRuby选项在你的虚拟主机，检查此链接到乘客文档： http://www.modrails.com/documentation/Users%20guide%20Apache.html#PassengerDefaultRuby

也可以尝试使用一个单独的每个应用程序的虚拟主机。

Answer 2

/nonexistant是'nobody'用户的主目录。换句话说，Phusion Passenger试图以'nobody'用户的身份运行您的应用程序，并且因为该用户没有有效的主目录而失败。

您可能并未打算将您的应用作为“无人”用户运行。为了解决这个问题，将你的config.ru配置给你想要运行的用户。欲了解更多信息，请阅读User switching support in Phusion Passenger。
