我想用一個額外的mqtt-client啟動一個apache-server。我在生產(chǎn)中使用Django和Apache。要啟動我的mqqt客戶端，我編輯了wsgi.py它，如果我使用的是開發(fā)服務器（python3 manage.py runserver），則可以正常運行。但是它不能在生產(chǎn)中工作。請問有什么幫助或有想法如何讓apache在生產(chǎn)中起作用嗎？wsgi.py：import osimport threadingimport logginglogger = logging.getLogger('mqtt')from django.core.wsgi import get_wsgi_applicationos.environ.setdefault("DJANGO_SETTINGS_MODULE", "iot.settings")from iot.settings import MQTT_CONNECTION, MQTT_BROKERif 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客戶端：import jsonimport threadingimport loggingimport paho.mqtt.client as mqttfrom device.models import Devicefrom value.models import Valuefrom iot.settings import MQTT_BROKERlogger = 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()
