如何使用 Supervisor（包括 Gunicorn 和 Nginx）設置多個 Django 應用程序？綁定到:::::::8090 失敗（98：地址已在使用中）
我已經使用 Supervisor、Gunicorn 和 Nginx（在 Debian Buster 上）部署了一個 Django/Wagtail 應用程序，所以我可以通過http://xx.xxx.xxx.xxx:8090訪問它。
/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 autostart=true autorestart=true/etc/supervisor/conf.d/nginx-mysite-admin.conf [program:nginx-mysite-admin] command=/usr/sbin/nginx -g "daemon off;" autostart=true autorestart=true stderr_logfile=/home/www.mysite.com/.local/share/virtualenvs/cms-WqsZ9qOt/var/log/nginx-error.log stdout_logfile=/home/www.mysite.com/.local/share/virtualenvs/cms-WqsZ9qOt/var/log/nginx-access.log stderr_logfile_maxbytes=2MB 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'現在我以同樣的方式添加了另外 2 個 Django 應用程序。不幸的是，主管無法提出他們。有時 3 次執行中有 1 次執行，但大多數時候它們都不起作用。如果它有效，它會創建 3 個程序（idk，如果它應該是這樣的話）。

看起來 nginx 只抱怨 IPV6 地址。你需要ipv6嗎？如果你不這樣做，那麼刪除 ipv6 的偵聽塊將使 nginx 僅在 ipv4 上正常啟動。如果您在 nginx 中確實需要 IPV6 偵聽器，那麼您可以執行以下操作
fuser -k 8090/tcp這將殺死 PID 保持埠 8090。對您需要的其餘埠執行相同操作。一種更嚴厲的方法是完全殺死 nginx（假設它是保持埠打開的那個）
pkill -f nginx & wait $! service nginx restart
