我在本地主机(windows)上设置了工作进程,它可以正常运行,但在heroku上却不起作用。
我正在使用Django,Reddis和Celery。
celery.py
from __future__ import absolute_import, unicode_literals
import os
from celery import Celery
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'eco_gestao.settings')
app = Celery('eco_gestao')
app.config_from_object('django.conf:settings', namespace='CELERY')
app.autodiscover_tasks()
@app.task(bind=True)
def debug_task(self):
print('Request: {0!r}'.format(self.request))
Procfile:
web: gunicorn eco_gestao.wsgi --log-file -
worker: celery -A eco_gestao worker -l info
设置:
CELERY_RESULT_BACKEND = 'django-db'
CELERY_BROKER_URL = 'redis://'
# BROKER_URL = os.getenv('REDISTOGO_URL', 'redis://127.0.0.1:6380')
CELERY_ACCEPT_CONTENT = ['application/json']
CELERY_RESULT_SERIALIZER = 'json'
CELERY_TASK_SERIALIZER = 'json'
redis_host = os.environ.get('REDIS_HOST', 'localhost')
# Channel layer definitions
# http://channels.readthedocs.org/en/latest/deploying.html#setting-up-a-channel-backend
CHANNEL_LAYERS = {
"default": {
# This example app uses the Redis channel layer implementation asgi_redis
"BACKEND": "asgi_redis.RedisChannelLayer",
"CONFIG": {
"hosts": [(redis_host, 6379)],
},
"ROUTING": "multichat.routing.channel_routing",
},
}
错误:
[2019-08-21 17:33:22,075: ERROR/MainProcess] consumer: Cannot connect to redis://localhost:6379//: Error 111 connecting to 127.0.0.1:6379. Connection refused.
答案 0 :(得分:0)
您必须通过导出正确的REDIS_HOST值来配置在Heroku上运行的Celery以使用您的Heroku Redis(我看到您正在从环境中选择Redis主机)。显然,该值不会导出(这就是为什么您获得Cannot connect to redis://localhost:6379//
的原因。)
