ruby-on-rails - 使用 Passenger/Capistrano 部署到 Nginx 服务器后图像不显示

Question

您好，我正在使用 Capistrano 将我的第一个 Rails 应用程序部署到 Ubuntu 16 服务器，除了图像未在生产环境中显示外，一切都很顺利。

在生产服务器上，图像位于此路径中:/myapp/current/public/assets

但是如果我在浏览器中查看这个，我的损坏的图片链接会给我这个(见图片)，这是标题图片的损坏链接。

奇怪的是在/myapp/current/public/assets中有一个.svg文件在浏览器中完美显示，在图片中下面是显示的路径

这是我的Capfile

# Load DSL and set up stages
 require "capistrano/setup"

# Include default deployment tasks
require "capistrano/deploy"


set :rbenv_type, :user # or :system, depends on your rbenv setup
set :rbenv_ruby, '2.3.1'


require 'capistrano/rbenv'

require 'capistrano/bundler'
require 'capistrano/rails'


# Load custom tasks from `lib/capistrano/tasks` if you have any defined
Dir.glob("lib/capistrano/tasks/*.rake").each { |r| import r }

这是config/deploy.rb

# config valid only for current version of Capistrano
lock '3.6.1'

set :application, 'myapp'
set :repo_url, 'git@github.com:DadiHall/myapp.git'


 # Default deploy_to directory is /var/www/my_app_name
 set :deploy_to, '/home/deploy/myapp'


 set :linked_files, %w{config/database.yml config/secrets.yml}
 set :linked_dirs, %w{bin log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system}

 namespace :deploy do

 desc 'Restart application'
 task :restart do
  on roles(:app), in: :sequence, wait: 5 do
   execute :touch, release_path.join('tmp/restart.txt')
  end
 end

 after :publishing, 'deploy:restart'
 after :finishing, 'deploy:cleanup'

结束

这是environments/production.rb

Rails.application.configure do

config.cache_classes = true
config.consider_all_requests_local       = false
config.action_controller.perform_caching = true
config.serve_static_files = ENV['RAILS_SERVE_STATIC_FILES'].present?
config.assets.js_compressor = :uglifier


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

 config.assets.digest = true
 config.assets.initialize_on_precompile = false

 # `config.assets.precompile` and `config.assets.version` have moved to config/initializers/assets.rb


 config.log_level = :debug

 config.i18n.fallbacks = true

 config.active_support.deprecation = :notify

 config.log_formatter = ::Logger::Formatter.new

 config.active_record.dump_schema_after_migration = false

Braintree::Configuration.environment = :sandbox
Braintree::Configuration.merchant_id = ENV['merchant_id']
Braintree::Configuration.public_key = ENV['public_key']
Braintree::Configuration.private_key = ENV['private_key']

end

在 /etc/nginx/sites-enabled/default 我有以下几行

server {
    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;

    server_name mydomain.com;
    passenger_enabled on;
    rails_env    production;
    root         /home/deploy/myapp/current/public;

    # redirect server error pages to the static page /50x.html
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   html;
    }
}

这是nginx的错误日志

我已经尝试过 bundle exec rake assets precompile 但没有成功。

我一次又一次地部署并重新启动了 nginx，没有任何运气

我已经尝试了几乎所有关于堆栈溢出的类似问题的答案，但似乎没有任何效果。

我是不是漏掉了什么？

我确定这个问题与 Assets 管道有关，但我不确定如何解决。

任何人都可以看看这个并给我建议。

提前致谢

好的，如果有人遇到类似的问题，您可能需要查看 config.assets.compile 在我的例子中，我只需要更改 config/environments/production.rb config .assets.compile 来自 false，我将其更改为 true 现在一切正常....我只花了两天时间就弄明白了 :D
