Question

我有一个config/deploy.rb文件，如下所示：

# require './config/boot'
# config valid only for Capistrano 3.2
lock '3.9.0'

set :application, 'arthousecoop'
set :repo_url, 'git@github.com:arthousecoop/arthousecoop.git'
set :ssh_options, {forward_agent: true}

set :deploy_to, '/home/sbp/rails'

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

# Default value for default_env is {}
# set :default_env, { path: "/opt/ruby/bin:$PATH" }


namespace :deploy do
  # before :deploy, 'rvm1:install:gems'
  # before :deploy, 'deploy:check_revision'
  # after :finishing, 'deploy:cleanup'

  desc 'Restart application'
  task :restart do
    on roles(:app), in: :sequence, wait: 5 do
      within release_path do
        execute :bundle, 'exec thin restart -C /etc/thin/sbp.yml'
      end
    end
  end

  after :publishing, :restart
  before :restart, 'rvm:hook'
  after :finished, 'airbrake:deploy'

  # 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

linked_files和linked_dirs部分的作用是什么？

文档说：

：linked_files默认值：[]列出的文件将从中进行符号链接应用程序的共享文件夹到每个版本目录期间部署。可以用于持久化配置文件 database.yml的。请参阅结构以获取确切的目录。

我真的不明白这意味着什么？符号链接是什么意思？

on roles部分是什么意思？ on方法有什么作用？

task :restart do
on roles(:app), in: :sequence, wait: 5 do
  within release_path do
    execute :bundle, 'exec thin restart -C /etc/thin/sbp.yml'
  end

是release_path Capistrano方法吗？

了解此capistrano部署文件
