完整披露我本来在run目录中有一个gunicorn.socket文件，但由于我认为它可以解决另一个问题，所以我愚蠢地删除了它。现在我似乎无法找回。我是运气不好还是有希望？
这是我的/etc/systemd/system/gunicorn.service文件：
[Unit]
Description=gunicorn daemon
Requires=gunicorn.socket
After=network.target
[Service]
User=whodini
Group=www-data
WorkingDirectory=/home/whodini/project
ExecStart=/home/whodini/project/env/bin/gunicorn --access-logfile - --workers 3 --bind unix:/run/gunicorn.sock project.wsgi:application
[Install]
WantedBy=multi-user.target
这是我的/etc/systemd/system/gunicorn.socket文件：
[Unit]
Description=gunicorn socket
[Socket]
ListenStream=/run/gunicorn.sock
SocketUser=whodini
SocketGroup=www-data
[Install]
WantedBy=sockets.target
这是以下命令的输出：
root@project-server:/run# sudo systemctl status gunicorn.socket
● gunicorn.socket - gunicorn socket

Warning: Journal has been rotated since unit was started. Log output is incomplete or unavailable.
和随后的文件查找：
root@project-server:/run# file /run/gunicorn.sock
/run/gunicorn.sock: cannot open `/run/gunicorn.sock' (No such file or directory)
在有帮助的情况下存在此问题：

在过去的几天里，我一直在尝试解决此问题，包括帮助Digital Digital提供帮助，并在google上搜索类似的答案，但到目前为止没有任何效果。
