Django和Apache：为MQTT Client启动附加线程

Question

我想用一个额外的mqtt-client启动一个apache-server。我在生产中使用Django和Apache。要启动我的mqqt客户端，我编辑了wsgi.py它，如果我使用的是开发服务器（python3 manage.py runserver），则可以正常运行。但是它不能在生产中工作。请问有什么帮助或有想法如何让apache在生产中起作用吗？

wsgi.py：

import os

import threading

import logging

logger = logging.getLogger('mqtt')

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "iot.settings")

from iot.settings import MQTT_CONNECTION, MQTT_BROKER

if MQTT_CONNECTION:

    logger.debug('Connecting to Broker...')

    try:

        from utils_mqtt_client.mqtt_client import run_client

        run_client()

    except Exception as e:

        logger.debug('Could not conntect to MQTT Broker:\n\t {}'.format(e))

else:

    logger.debug('Starting without MQTT connection')

application = get_wsgi_application()

mqqt客户端：

import json

import threading

import logging

import paho.mqtt.client as mqtt

from device.models import Device

from value.models import Value

from iot.settings import MQTT_BROKER

logger = logging.getLogger('mqtt')

topics = ['config']

CLIENT = mqtt.Client('webserver')

# [...]

def run_client():

    devices = Device.objects.all()

    CLIENT.on_connect = on_connect

    CLIENT.on_message = on_message

    for device in devices:

        subscribe(CLIENT, device)

    CLIENT.connect(MQTT_BROKER)

    CLIENT.loop_start()
