Rails Capistrano 在本地预编译资产未在生产中加载

Question

我将我的 rails 应用程序部署到 AWS 服务器并尝试运行 rake 资产：在本地预编译并在部署时上传。由于服务器上的内存不足问题，

这是我的 deploy.rb

# config valid only for current version of Capistrano
lock '3.5.0'

set :application, 'fullpower_tee'
set :repo_url, 'git_repo' # Edit this to match your repository
set :branch, :master
set :deploy_to, '/home/deploy/fullpower_tee'
set :pty, true
set :linked_files, %w{config/database.yml config/application.yml}
set :linked_dirs, %w{bin log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system public/uploads}
set :keep_releases, 2
set :rvm_type, :user
set :rvm_ruby_version, 'ruby-2.2.1'


set :puma_rackup, -> { File.join(current_path, 'config.ru') }
set :puma_state, "#{shared_path}/tmp/pids/puma.state"
set :puma_pid, "#{shared_path}/tmp/pids/puma.pid"
set :puma_bind, "unix://#{shared_path}/tmp/sockets/puma.sock"    #accept array for multi-bind
set :puma_conf, "#{shared_path}/puma.rb"
set :puma_access_log, "#{shared_path}/log/puma_error.log"
set :puma_error_log, "#{shared_path}/log/puma_access.log"
set :puma_role, :app
set :puma_env, fetch(:rack_env, fetch(:rails_env, 'production'))
set :puma_threads, [0, 8]
set :puma_workers, 0
set :puma_worker_timeout, nil
set :puma_init_active_record, true
set :puma_preload_app, false


namespace :deploy do
  namespace :assets do

    Rake::Task['deploy:assets:precompile'].clear_actions

    desc 'Precompile assets locally and upload to servers'
    task :precompile do
      on roles(fetch(:assets_roles)) do
        run_locally do
          with rails_env: fetch(:rails_env) do
            execute 'bin/rake assets:precompile'
          end
        end

        within release_path do
          with rails_env: fetch(:rails_env) do
            old_manifest_path = "#{shared_path}/public/assets/manifest*"
            execute :rm, old_manifest_path if test "[ -f #{old_manifest_path} ]"
            upload!('./public/assets/', "#{shared_path}/public/", recursive: true)
          end
        end

        run_locally { execute 'rm -rf public/assets' }
      end
    end

  end
end

namespace :deploy do

  after :restart, :clear_cache do
    on roles(:web), in: :groups, limit: 3, wait: 10 do
      # Here we can do anything such as:
      # within release_path do
      #   execute :rake, 'cache:clear'
      # end
    end
  end

end

还有我的 config/environments/production.rb

  # Compress JavaScripts and CSS
  config.assets.compress = true

  # Don't fallback to assets pipeline if a precompiled asset is missed
  config.assets.compile = false

  # Generate digests for assets URLs
  config.assets.digest = true

  # config.assets.precompile += %w( *.css *.js )

  # Add the fonts path
  config.assets.paths << "#{Rails.root}/app/assets/fonts"

  # Precompile additional assets
  config.assets.precompile += %w( .svg .eot .woff .ttf )
  config.assets.precompile += %w( *.js )
  config.assets.precompile += [ 'admin.css',

                                ]

我的 application.rb 有

config.assets.initialize_on_precompile = false

capistrano 部署成功地能够在本地预编译资产，然后将其上传到 shared/public 目录，但是我看不到资产加载到我的网站上，从一天开始就陷入这个问题请帮助！

鉴于您的 URL 是 404，并且它不会显示请求包含哈希，您需要确保在您的布局/视图文件中使用 stylesheet_link_tag 来加载 css 文件。以及将 CSS 本身中的各种资产助手用于背景图像。

http://guides.rubyonrails.org/asset_pipeline.html#coding-links-to-assets

Capistrano 从 git 部署。如果您不想将共享资产推送到您的 github，则可以将其配置为从本地存储库中提取，但无论资产需要在源代码管理中。

set :repo_url, 'file:///path/to/repo/.git'

将其设置为本地存储库。

如果您绝对不想在您的 git 存储库中存储已编译的更改，您可以在 rake assets:precompile 完成后运行 scp 命令。

execute 'scp -r public/assets/* user@serverip:/var/www/apps/yourapppath/shared/public/assets/*'

当然让它指向正确的位置。

我还想认为您可以通过一些清单文件而不是预编译列表中的 30 个文件来稍微优化您的资产。
