分叉在Django

Question

我正在尝试在django视图中生成os.fork()并收到错误：Port 8000 already in use。据我所知，当我os.fork()文件描述符继承时，我在两个进程中的同一个端口中得到两个套接字。

   def view(request):
       ...
       if not os.fork():
          target()
       return

    def target(*args, **kwargs):
       ...
       sd = socket.socket(*args, **kwargs)
       sd.bind(*args)
       sd.listen()
       nsd = sd.accept()
      ...

如果我在子项中为已打开的描述符执行os.close()，则会收到WSGI错误：

for i in os.listdir("/proc/%s/fd" % os.getpid()):
   os.close(int(i))

Traceback (most recent call last):

    self._write('HTTP/%s %s\r\n' % (self.http_version,self.status))

我需要将这个exaclty作为单独的过程，我不想使用像芹菜这样的三维派对应用程序。

我认为正确的解决方案是使用芹菜（http://docs.celeryproject.org/en/latest/）或同等的。
