【问题描述】：
我是第一次在 upcloud 上设置 VPS。我正在使用带有 Nginx 的独角兽 5.5.5。 Rails 4.2.8 和 ruby 2.4.2。我的 Nginx 服务运行良好。不显示任何错误。每当我启动独角兽服务时，我都会收到此错误。我按照本教程进行操作。

我的 unicorn.sock 文件是空的，如果这是一个新手错误，我很抱歉，但我已经被这个问题困扰了 2 天。请帮帮我。 这是我在 etc/init.d 目录中的 unicorn_repo 文件
#!/bin/sh
### BEGIN INIT INFO

CMD="cd $APP_ROOT && bundle exec unicorn -c config/unicorn.rb -E $ENV -D"

OLD_PID="$PID.oldbin"
这是我的 nginx/默认文件
upstream app {

}

server_name localhost;

}
error_page 500 502 503 504 /500.html;
client_max_body_size 4G;

}
这是我的 unicorn.rb 文件。

我不是 100% 确定，但我不喜欢一件事：在你的独角兽初始化文件中，你使用的是
USER=root。首先，一个好的建议是始终使用不同于 root 的用户。此外，EC2 实例的默认用户通常是ubuntu。尝试改变它。如果不起作用，请尝试将套接字路径从/tmp/unicorn.sock移动到另一个路径，例如/home/ubuntu/unicorn.sock。如果没有任何效果，请将您的config/unicorn.rb文件也添加到问题中。 -
我已经添加了 unicorn.rb 。先生，为什么它说“它不是套接字，我觉得 unicorn.sock 中应该有一些代码但它是空的”。你怎么看？
