ruby-on-rails – 使用capistrano在生产中运行rpush作为守护进程

我已经设置了我的rails应用程序与rpush一起使用.它使用rpush start在开发中在本地工作正常.但是现在我想使用capistrano-2.15.5将它部署到我的EC2服务器上.

部署我的deploy.rb：

after "deploy:stop",    "delayed_job:stop"
after "deploy:stop",    "rpush:stop"

after "deploy:start",   "delayed_job:start"
after "deploy:start",   "rpush:start"

after "deploy:restart", "delayed_job:restart"
after "deploy:restart", "rpush:restart"

namespace :rpush do
  %w[start stop restart].each do |command|
    desc "#{command} rpush deamon"
    task command, roles: :app, except: {no_release: true} do
      run "cd #{deploy_to}/current && bundle exec rpush #{command}"
    end
  end
end

现在,问题

>它从开发环境开始.我试着理解this页面告诉我该怎么做,但我做不到.
>我不知道pid是否存储在/ current目录或/ shared目录中.它应该在共享中,以便文件在部署之间保持不变

如果有人这样做(即使以不同的方式),请告诉我如何.

或者,我如何修复我的cap配方和/ initializers / rpush

对于Capistrano 3：

after :finished, :restart_rpush do
  on roles(:web) do
    within release_path do
      with rails_env: fetch(:rails_env) do
        execute :bundle, :exec, "rpush stop -e #{fetch(:rails_env)}"
        execute :bundle, :exec, "rpush start -e #{fetch(:rails_env)}"
      end
    end
  end
end

然后检查tmp和其他目录是否正确链接：

set :linked_dirs, %w{log tmp/pids tmp/cache tmp/sockets vendor/bundle publichttp://img.558idc.com/uploadfile}
