Question

我已经设置了用于部署Rails应用程序的服务器。我无法启动独角兽服务。这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。我为套接字创建了共享文件夹，即服务器上的PID。但是在每个发行版之后，我都使用mina进行部署，而我手动创建的共享文件夹消失了，并且与旧发行版中的独角兽文件一起消失了。因此，我在本地桌面上创建了共享文件夹，但是它们并没有通过git推送到服务器。所以我的文件应该放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

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

set -e

    case $1 in

我的mina deploy.rb文件

需要'mina / bundler' 需要'mina / rails' 需要'mina / git' 需要'mina / rbenv'＃以获得rbenv支持。（http://rbenv.org）

我遇到此错误

将它们保留在共享文件夹中，您可以在共享文件夹中创建指向tmp文件夹的符号链接。

在mina部署Rails应用程序后，文件夹会自动消失，从而在哪里保存独角兽PIDS和套接字路径
