Rails Passenger / Capistrano / ubuntu应用不提供资产

Question

After changing css files I did a rake assets:precompile and pushed it up to git. Then did a new deploy with capistrano to my server. Now none of my assets or styles are showing up on my page http://162.243.102.157/ .
The assets are on the production deployment server, but I can't seem to figure out why either passenger or Rails isn't serving and showing the assets to my website...?

My ruby -v is:
2.2.3p173

Rails -v:
4.2.5.2

capfile:

# Load DSL and set up stages
require 'capistrano/setup'
# Include default deployment tasks
require 'capistrano/deploy'
# Include tasks from other gems included in your Gemfile

Update:

Assets and styles are now showing up, but I can't seem to update anything. Now when I git push and deploy, the assets don't update to the new changes...

You can set the config.serve_static_files setting to true or make your web server serve these files. I use Nginx (along with passenger) with this config :

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