sprockets无法为nginx准备资产

Question

我想让nginx为缓存任务提供静态文件。

但我从nginx错误日志中得到No such file or directory。

似乎无法提供root-c452663d516929cd4bb4c1cd521971eb.css中包含的css文件。

我该如何修复错误

production.rb

  # Disable serving static files from the `/public` folder by default since
  # Apache or NGINX already handles this.
  #config.serve_static_files = ENV['RAILS_SERVE_STATIC_FILES'].present?
  config.serve_static_files = false

  # Compress JavaScripts and CSS.
  config.assets.js_compressor = :uglifier
  # config.assets.css_compressor = :sass

  # Do not fallback to assets pipeline if a precompiled asset is missed.
  config.assets.compile = true

nginx设置

location / {
try_files $uri @sample;
gzip_static       on;
expires           max;
add_header        Cache-Control public;
}

location @sample {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;
    proxy_pass http://sample;
}
  location ~* ^/assets/ {
      # Per RFC2616 - 1 year maximum expiry
      expires 1y;
      add_header Cache-Control public;

      # Some browsers still send conditional-GET requests if there's a
      # Last-Modified header or an ETag header even if they haven't
      # reached the expiry date sent in the Expires header.
      add_header Last-Modified "";
      add_header ETag "";
      break;
    }
