关于Gunicorn日志文件中出现错误的原因有什么线索吗？正如我所说，一切都在顺利进行。唯一的问题是此日志不断发送错误

非常感谢，

正如错误日志所说，似乎有一个应用程序已经在侦听端口8000。也许您从命令行ant启动了gunicorn，它已经在该端口中运行

您可以使用netstat-tulpn查看是否有python实例在该端口上侦听并终止它

希望这会有所帮助。

这通常发生在gunicorn进程重试几次时，以及在上一个进程即将完成时，您碰巧在端口上启动了一个进程（在您的情况下为8000），等等。因此，您需要单独终止所有此类进程

您可以使用
```
netstat-tulpn
```
查看PID
```
kill-9PID
```

在循环等待情况下，其他等待过程将自动启动。因此，反复使用

netstat

检查并杀死它们，直到在该端口上发现不再有进程运行

Gunicorn进程在这一点上应该可以正常工作。

python manage.py run\u Gunicorn

run as a deamon？看起来像是supervidor错误地重新启动了程序。查看主管日志。supervidor告诉您的程序正在崩溃。您的程序需要一个virtualenvironment？Searh来获取第一条错误消息，在使用

连接之前：

错误。让我们添加我的“netstat-tulpn”输出。Python在PID 2719上运行，与supervisord进程的PID相同。
