Gunicorn 不创建 MyProject.sock 文件

Question

我不是 Unix 专家，并且在 Ubuntu 服务器 (20.04.5 LTS) 上的 Azure 上运行 WebApp 时遇到问题，gunicorn.service 不会创建 MyProjet.sock 文件。具体来说，WebApp 始终有效，从一天到第二天 MyProject.sock 文件被删除，我无法重新创建它。

我尝试遵循此处和 StackOverflow 上找到的几个解决方案，更准确地说是这个命令序列

sudo systemctl stop nginx 
sudo systemctl stop gunicorn.service
sudo systemctl restart nginx
sudo systemctl daemon-reload
sudo systemctl restart gunicorn.service
sudo systemctl status gunicorn.service

我得到的结果如下

● gunicorn.service - gunicorn daemon
     Loaded: loaded (/etc/systemd/system/gunicorn.service; enabled; vendor preset: enabled)
     Active: failed (Result: exit-code) since Fri 2024-01-12 13:40:11 UTC; 1min 18s ago

我注意到，如果我尝试通过连接命令来一次执行所有命令，则该服务似乎可以正常工作

sudo systemctl stop nginx && sudo systemctl stop gunicorn.service && sudo systemctl restart nginx && sudo systemctl daemon-reload && sudo systemctl restart gunicorn.service && sudo systemctl status gunicorn.service
● gunicorn.service - gunicorn daemon
     Loaded: loaded (/etc/systemd/system/gunicorn.service; enabled; vendor preset: enabled)

Jan 12 13:40:10 DeployUbuntu systemd[1]: Started gunicorn daemon.

但如果我立即执行

sudo systemctl status gunicorn.service

它给了我上面指出的错误消息。

在我的古尼康服务

[Unit]
Description=gunicorn daemon
After=network.target

[Service]

[Install]
WantedBy=multi-user.target

我想补充一点，我已经尝试卸载并重新安装gunicorn 和该项目。最后，我想补充一下，使用的gunicorn版本是20.1.0，这是由于项目规范所致。
