我正在将django应用程序移动到python3 / django 1.10。该流程的一部分还包括新部署，我们使用AWS EBS。
芹菜任务在迁移之前是可以的，但现在我无法使任务正常工作。
包裹：
...
celery==3.1.23
Django==1.10.6
django-celery==3.2.1
...
的Python：
Python 3.4.3
在supervisor配置中，我添加了一个运行celery的配置：
[program:celeryd-workers]
; Set full path to celery program if using virtualenv
command=/opt/python/run/venv/bin/python /opt/python/current/app/manage.py celery worker -A app --app=app.celery_app:app -l DEBUG -c 4
directory=/opt/python/current/app
user=nobody
numprocs=1
autostart=true
autorestart=true
startsecs=10
stopwaitsecs = 600
killasgroup=true
stdout_logfile=/var/log/celery-worker.log
stderr_logfile=/var/log/celery-worker.log
environment=PYTHONPATH="/opt/python/current/app/:",PATH="/opt/python/run/venv/bin/:%(ENV_PATH)s",DJANGO_SETTINGS_MODULE="settings.qa"
[program:celeryd-beat]
; Set full path to celery program if using virtualenv
command=/opt/python/run/venv/bin/python /opt/python/current/app/manage.py celery beat -A app --app=app.celery_app:app --loglevel=DEBUG --workdir=/tmp --pidfile=/tmp/celerybeat.pid -s /tmp/celerybeat-schedule.db
directory=/opt/python/current/app
user=nobody
numprocs=1
autostart=true
autorestart=true
startsecs=10
stopwaitsecs = 600
killasgroup=true
stdout_logfile=/var/log/celery-beat.log
stderr_logfile=/var/log/celery-beat.log
environment=PYTHONPATH="/opt/python/current/app/:",PATH="/opt/python/run/venv/bin/:%(ENV_PATH)s",DJANGO_SETTINGS_MODULE="settings.qa"
我的celery_app.py非常简单：
from __future__ import unicode_literals, absolute_import
from celery import Celery
from django.conf import settings
app = Celery()
app.config_from_object('django.conf:settings')
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)
配置
在EC2实例上，芹菜的设置为：
BROKER_URL = 'the aws elastic cache redis url'
CELERY_RESULT_BACKEND = 'djcelery.backends.database:DatabaseBackend'
BROKER_TRANSPORT_OPTIONS = {
'visibility_timeout': 600,
}
BROKER_POOL_LIMIT = 1
CELERY_ACCEPT_CONTENT = ['pickle', 'json', 'msgpack']
CELERY_DEFAULT_QUEUE = 'default'
CELERY_QUEUES = {
'default': {
'exchange': 'default',
'exchange_type': 'topic',
'binding_key': 'tasks.#'
}
}
CELERY_ALWAYS_EAGER = True
从我检查配置的实例（来自django.conf导入设置），我检查了实例是否可以使用redis-cli连接到redis。
基本上如果我运行一个任务，即使是最简单的任务，如芹菜文档中的add(x,y)，我也没有在./manage.py celery events中完成任务，我把事件留给了一对夫妇几个小时，我试图从应用程序运行任务，但没有任何反应，似乎卡住了。
No task selected │
│ Workers online: celery@ip-xx-xx-xx-xx │
│ Info: events: 2187 tasks:0 workers:1/1
│ Keys: j:down k:up i:info t:traceback r:result c:revoke ^c: quit
奇怪的是，如果我在我的应用程序中的文档中运行此任务：
In [1]: from app.core.tasks import add
In [2]: result = add.delay(2,2)
In [3]: result.get()
Out[3]: 4
结果显示，但我看不到事件中的任何任务，如果我查看celery inspect statistics
...
"pool": {
"max-concurrency": 4,
"max-tasks-per-child": "N/A",
"processes": [

],

似乎没什么用。
当然这个过程正在运行：

芹菜打败了：

>>>> Testing: False
celery beat v3.1.23 (Cipater) is starting.

你知道我做错了吗？
答案 0 :(得分：0)
您的设置文件有
CELERY_ALWAYS_EAGER = True
这基本上意味着它将跳过队列并在本地运行任务。因此，您无需看到任何事件即可获得结果。
看看http://docs.celeryproject.org/en/latest/userguide/configuration.html#std:setting-task_always_eager
我会尝试删除该设置并从那里开始工作。
