Rails 6 + Capistrano - 没有这样的 puma.sock 文件

拜托，我有一个大问题10多个小时了。

每当我使用 Capistrano 和 Puma 在 Rails 中运行应用程序部署并重新启动 nginx 时，当我尝试访问我的 Web 时，我会看到此错误：

当我访问 nginx 日志时，我看到以下错误：

2020/12/29 04:09:50 [crit] 9536#9536: *73 connect() to unix:///home/ubuntu/apps/my_app/shared/tmp/sockets/my_app-puma.sock failed (2: No such file or directory) while connecting to upstream, client: [CLIENT_ID], server: , request: "GET / HTTP/1.1", upstream: "http://unix:///home/ubuntu/apps/my_app/shared/tmp/sockets/my_app-puma.sock:/", host: "[MY_HOST]"

预先感谢某人的帮助。因为我已经尝试解决丢失“.sock”文件的问题超过10个小时了，但我无法解决

更新1：

按照我创建的教程：

我在路径中创建：/etc/systemd/system一份文件：puma-website.service

里面有：

After=network.target
[Service]
# Foreground process (do not use --daemon in ExecStart or config.rb)
Type=simple

# Preferably configure a non-privileged user
User=ubuntu
Group=ubuntu

# Specify the path to your puma application root
WorkingDirectory=/home/ubuntu/my_app/current

# Helpful for debugging socket activation, etc.
Environment=PUMA_DEBUG=1

#EnvironmentFile=/var/www/my-website.com/.env
# The command to start Puma
ExecStart=/home/ubuntu/.rbenv/shims/bundle exec puma -C /home/ubuntu/my_app/current/config/puma.rb
Restart=always

[Install]
WantedBy=multi-user.target

但我错误： ：/etc/systemd/system$ sudo systemctl status puma-website.service
