Rails assets missing after Capistrano deploy

问题

I'm building a VPS, and it's deployed via Capistrano, database connected etc, but there are no assets available to the page - it is basic html only.

The assets appear to be compiled, and exist in the shared directory.

From the page html:

<link href="/assets/application-a1b5d69aeaff709fd3dce163c559b38b.css" media="all" rel="stylesheet" type="text/css" />
<script src="/assets/application-0ebd07089629f8c6880dddfb688d525d.js" type="text/javascript"></script>

The asset files appear to exist in the shared directory:

assay@assaypipeline:~/apps/assay/shared/assets$ ls application-  a1b5d69aeaff709fd3dce163c559b38b.css
application-a1b5d69aeaff709fd3dce163c559b38b.css

When I view, source and then click on the hyperlink to the asset path, I get a 404 not found from Nginx.

SOLUTION

Thanks to Martin M (accepted answer) for help. The steps I took, from the ~/apps/(app name)/current directory on the server.

$ bundle install
$ RAILS_ENV=production bundle exec rake assets:precompile
$ sudo service nginx restart

Obviously it would be better to include this in the Capistrano recipe.

*EDIT - Capfile *

load 'deploy'
load 'deploy/assets'
load 'config/deploy'

回答1:

Your precompiled assets should reside in public/assets, see rails guides
normally you create them by running

RAILS_ENV=production bundle exec rake assets:precompile

as part of your deployment.
The shared stuff is to provide old stuff over several deploys.

The problem might not be in asset compilation and deployment. Try changing nginx root /home/deploy/app_name/public; to /home/deploy/app_name/current/public; in nginx configuration file /etc/nginx/sites-enabled/default.

sudo nano /etc/nginx/sites-enabled/default

following is my configuration file

upstream app {
  # Path to Puma SOCK file, as defined previously
  server unix:/home/deploy/app_name/shared/tmp/sockets/puma.sock fail_timeout=0;
}
server {
  listen 80;
  server_name localhost;

  root /home/deploy/app_name/current/public;

  try_files $uri/index.html $uri @app;

  location / {
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header Host $host;
    proxy_redirect off;
    proxy_http_version 1.1;
    proxy_set_header Connection '';
    proxy_pass http://app;
  }

  location ~ ^/(assets|fonts|system)/|favicon.ico|robots.txt {
    gzip_static on;
    expires max;
    add_header Cache-Control public;
  }

  error_page 500 502 503 504 /500.html;
  client_max_body_size 4G;
  keepalive_timeout 10;
}

Hope this helps
