在nginx上部署多個Ruby on Rails應用程序

Question

我有兩個RoR應用程序，一個是使用ruby 2.0.0，名爲dataentry3的gemset（rvm使用2.0.0@dataentry3），第二個應用程序使用ruby 1.9.3 @ V1。

我試圖部署方式如下這些應用程序：

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

5. 編輯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）。

完成這些步驟之後我試圖部署上的地址http://my-ip/v1秒應用程序（新PHUSION乘客允許運行多個Ruby版本，see here）

步驟我做：

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

4. 編輯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; 
   } 
   } 
   
   } 
   

在此之後，第二應用（http://my-ip/v1）不工作。我收到提示：

必須有紅寶石2.0.0和Ruby-1.9.3乘客寶石之間的衝突。我不明白爲什麼，因爲新版本的乘客是支持這一點的。在passenger_root指令更改爲/usr/local/rvm/gems/ruby-1.9.3-p429@v1/gems/passenger-4.0.3後第二個應用程序開始工作，但第一個不是（幾乎相同的錯誤日誌）。

Answer 1

您寬設置紅寶石版本的系統與rvm use...

您需要使用PassengerRuby選項在你的虛擬主機，檢查此鏈接到乘客文檔： http://www.modrails.com/documentation/Users%20guide%20Apache.html#PassengerDefaultRuby

也可以嘗試使用一個單獨的每個應用程序的虛擬主機。

Answer 2

/nonexistant是'nobody'用戶的主目錄。換句話說，Phusion Passenger試圖以'nobody'用戶的身份運行您的應用程序，並且因爲該用戶沒有有效的主目錄而失敗。

您可能並未打算將您的應用作爲「無人」用戶運行。爲了解決這個問題，將你的config.ru配置給你想要運行的用戶。欲瞭解更多信息，請閱讀User switching support in Phusion Passenger。
