![如何使用 Supervisor（包括 Gunicorn 和 Nginx）设置多个 Django 应用程序？bind() 到 [::]:8090 失败（98：地址已在使用中）](https://linux22.com/image/769178/%E5%A6%82%E4%BD%95%E4%BD%BF%E7%94%A8%20Supervisor%EF%BC%88%E5%8C%85%E6%8B%AC%20Gunicorn%20%E5%92%8C%20Nginx%EF%BC%89%E8%AE%BE%E7%BD%AE%E5%A4%9A%E4%B8%AA%20Django%20%E5%BA%94%E7%94%A8%E7%A8%8B%E5%BA%8F%EF%BC%9Fbind()%20%E5%88%B0%20%5B%3A%3A%5D%3A8090%20%E5%A4%B1%E8%B4%A5%EF%BC%8898%EF%BC%9A%E5%9C%B0%E5%9D%80%E5%B7%B2%E5%9C%A8%E4%BD%BF%E7%94%A8%E4%B8%AD%EF%BC%89.png)
我已经使用 Supervisor、Gunicorn 和 Nginx（在 Debian Buster 上）部署了一个 Django/Wagtail 应用程序，因此我可以使用http://xx.xxx.xxx.xxx:8090。
/etc/nginx/sites-available/cms
server {
server_name xx.xxx.xxx.xxx;
listen 8090;
listen [::]:8090 ipv6only=on;

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。不幸的是，Supervisor 无法调出它们。有时 3 个中只有 1 个可以运行，但大多数时候都不起作用。如果它有效，它会创建 3 个进程（我不知道这是否应该是这样的）。
$ sudo lsof -i:8090

Nginx 错误日志给出98：地址已被使用，甚至在端口 81 上（将其作为默认端口，因为 Apache 使用 80），该端口未被使用。Apache 不应该是问题所在，因为即使关闭 Apache，它也无法工作。

答案1
看起来 nginx 只对 IPV6 地址有抱怨。你真的需要 ipv6 吗？如果不需要，那么删除 ipv6 的监听块将使 nginx 仅在 ipv4 上正常启动。如果你确实需要 nginx 中的 IPV6 监听器，那么你可以执行以下操作
fuser -k 8090/tcp
这将关闭占用 8090 端口的 PID。对您需要的其他端口执行相同操作。更严厉的方法是彻底关闭 nginx（假设它是占用端口的那个）
pkill -f nginx & wait $!
service nginx restart
