Rails Passenger/Capistrano/Ubuntu应用程序未提供资产

Question

更改css文件后，我做了一个rake资源：预编译并将其推送到git。然后对我的服务器做了一次capistrano的新部署。现在我的资产或样式都没有显示在我的页面http://162.243.102.157/上。
这些资产位于生产部署服务器上，但我似乎无法弄清楚为什么乘客或Rails未提供服务并将资产显示到我的网站......？

我的红宝石-v是：
2.2.3p173

的Rails -v：
4.2.5.2

更新：现在

资产和样式都显示出来，但我似乎无法进行任何更新。现在，当我推入并部署时，资产不会更新到新的更改...

Answer 1

您可以将config.serve_static_files设置为true或使您的Web服务器提供这些文件。 我使用Nginx（以及乘客）与此配置：

server { 
... 
passenger_enabled on; 
... 
location ~* ^/assets/ { 
    expires 1y; 
    add_header Cache-Control public; 
    add_header Last-Modified ""; 
    add_header ETag ""; 
    break; 
} 
}
