ruby-on-rails - 在 mina deploy rails app 后文件夹消失时，在哪里保存独角兽 PIDS 和套接字路径

问题描述

我已经设置了一个服务器来部署我的 rails 应用程序。我无法启动独角兽服务。它给了我一个失败的状态。我对此完全陌生。因此，按照本教程https://www.digitalocean.com/community/tutorials/how-to-deploy-a-rails-app-with-unicorn-and-nginx-on-ubuntu-14-04。我在服务器上为套接字创建了共享文件夹、PID。但是我在每次发布后都使用 mina 进行部署，我手动创建的共享文件夹消失了，并与带有独角兽文件的旧版本一起消失了。因此，我在本地桌面上创建了该共享文件夹，但它们没有通过 git 推送到服务器。那么我应该在哪里以及如何放置我的独角兽 pid 和套接字以使其在下面工作是我的文件

我的 unicorn.rb 文件

root = "/home/deployer/apps/rails_app/current"
working_directory root
pid "#{root}/shared/unicorn.pid"
stderr_path "#{root}/log/unicorn.log"
stdout_path "#{root}/log/unicorn.log"

listen "/shared/unicorn.railsapp.sock"
worker_processes 2
timeout 30

preload_app true

我的 /etc/init.d/unicorn_rails_app 文件
