ruby-on-rails - Rails delay_job 启动启动/停止 capistrano

Question

正如我在某处读到的，要在服务器启动时启动延迟作业，我应该在 config/deploy.rb 中写入以下内容：

require "delayed/recipes"

set :rails_env, "production" #added for delayed job

namespace :delayed_job do
  desc "Start delayed_job process" 
  task :start, :roles => :app do
    run "cd #{current_path}; script/delayed_job start #{rails_env}" 
  end

  desc "Stop delayed_job process" 
  task :stop, :roles => :app do
    run "cd #{current_path}; script/delayed_job stop #{rails_env}" 
  end

  desc "Restart delayed_job process" 
      task :restart, :roles => :app do
        run "cd #{current_path}; script/delayed_job restart #{rails_env}" 
  end
end

after "deploy:start", "delayed_job:start" 
after "deploy:stop", "delayed_job:stop" 
after "deploy:restart", "delayed_job:restart"

它不工作。事实上，我认为这个文件之前确实存在，但事实并非如此（我创建了它）。那么我应该怎么做才能让它继续工作呢？

还有更多问题，我应该怎么做才能在 Web 执行期间停止/重新启动作业处理？

试试看嘛：

desc "Restart delayed_job process"
    task :restart, :roles => :app do
     run "cd #{current_path}; RAILS_ENV=production bundle exec script/delayed_job restart #{rails_env}"
end

这应该有效。
