如何使用 Supervisor（包括 Gunicorn 和 Nginx）设置多个 Django 应用程序？bind() to [::]:8090 失败（98：地址已在使用中）

我已经使用 Supervisor、Gunicorn 和 Nginx（在 Debian Buster 上）部署了一个 Django/Wagtail 应用程序，所以我可以通过http://xx.xxx.xxx.xxx:8090访问它。

/etc/nginx/sites-available/cms

server {
    server_name xx.xxx.xxx.xxx;
    listen 8090;
    listen [::]:8090 ipv6only=on;
    error_log /home/www.mysite.com/.local/share/virtualenvs/cms-WqsZ9qOt/var/log/gunicorn-error.log;
    access_log /home/www.mysite.com/.local/share/virtualenvs/cms-WqsZ9qOt/var/log/gunicorn-access.log;

    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        root /home/www.mysite.com/www/my-site/cms/admin_panel;
    }
        location /media/ {
        root /home/www.mysite.com/www/my-site/cms/admin_panel;
    }

    location / {
        include proxy_params;
        proxy_pass http://unix:/home/www.mysite.com/.local/share/virtualenvs/cms-WqsZ9qOt/run/gunicorn.sock;
    }
}

/etc/supervisor/conf.d/guni-mysite-admin.conf

[program:guni-mysite-admin]
command=/home/www.mysite.com/.local/share/virtualenvs/cms-WqsZ9qOt/bin/gunicorn admin_panel.wsgi:application --config /home/www.mysite.com/.local/share/virtualenvs/cms-WqsZ9qOt/etc/gunicorn/conf.py
user=www.mysite.com

autorestart=true

/etc/supervisor/conf.d/nginx-mysite-admin.conf

[program:nginx-mysite-admin]

autostart=true

stdout_logfile_maxbytes=2MB

/home/www.mysite.com/.local/share/virtualenvs/cms-WqsZ9qOt/etc/gunicorn/conf.py

workers = 3
keepalive = 5
user = 'www.mysite.com'
proc_name = 'admin_panel'
loglevel = 'error'
errorlog = '/home/www.mysite.com/.local/share/virtualenvs/cms-WqsZ9qOt/var/log/gunicorn-error.log'
accesslog = '/home/www.mysite.com/.local/share/virtualenvs/cms-WqsZ9qOt/var/log/gunicorn-access.log'
bind = 'unix:/home/www.mysite.com/.local/share/virtualenvs/cms-WqsZ9qOt/run/gunicorn.sock'
raw_env = ['DJANGO_SETTINGS_MODULE=admin_panel.settings.production']
pythonpath = '/home/www.mysite.com/www/mysite/cms/admin_panel'

现在我以同样的方式添加了另外 2 个 Django 应用程序。不幸的是，主管无法提出他们。有时 3 次运行中有 1 次运行，但大多数时候它们都不起作用。如果它有效，它会创建 3 个进程（idk，如果它应该是这样的话）。

$ sudo lsof -i:8090

COMMAND  PID     USER   FD   TYPE    DEVICE SIZE/OFF NODE NAME
nginx   3631     root   16u  IPv4 961301189      0t0  TCP *:8090 (LISTEN)
nginx   3631     root   17u  IPv6 961301190      0t0  TCP *:8090 (LISTEN)
nginx   3632 www-data   16u  IPv4 961301189      0t0  TCP *:8090 (LISTEN)
nginx   3632 www-data   17u  IPv6 961301190      0t0  TCP *:8090 (LISTEN)
nginx   3633 www-data   16u  IPv4 961301189      0t0  TCP *:8090 (LISTEN)
nginx   3633 www-data   17u  IPv6 961301190      0t0  TCP *:8090 (LISTEN)

Nginx 错误日志给出98: Address already in use，即使在端口 81 上（将其作为默认端口，因为 Apache 正在使用 80），未使用。Apache 应该不是问题，因为它不起作用，即使 Apache 已关闭。

/var/log/nginx/error.log
