我不能让芹菜正常工作（aws elasticbeanstalk）

我要把django应用程序移到python3/django1.10。这个过程的一部分还包括一个新的部署，我们使用awsebs。在

在迁移之前，芹菜任务还可以，但现在我无法使任务正常工作。在

包装：

...
celery==3.1.23
Django==1.10.6
django-celery==3.2.1
...

Python：

^{pr2}$

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"

我的芹菜_应用程序副本很简单：

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：

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

从实例中我检查了配置（从django.conf公司导入设置），我检查了实例是否可以使用redis-cli连接到redis。在

什么不管用？在

基本上，如果我运行一个任务，即使是像celery文档中的add(x,y)这样最简单的任务，我在./manage.py celery events中没有得到任务，我让事件打开了几个小时，我试图从应用程序运行这些任务，但什么都没有发生，似乎卡住了。在

 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，如果我像应用程序中的文档那样运行此任务：

In [1]: from app.core.tasks import add

In [2]: result = add.delay(2,2)

In [3]: result.get()
Out[3]: 4

结果会出现，但我在事件中看不到任何任务，如果我检查celery inspect statistics

...
       "pool": {
            "max-concurrency": 4,
            "max-tasks-per-child": "N/A",
            "processes": [
                11363,
                11364,
                11365,
                11366
            ],
            "put-guarded-by-semaphore": false,
            "timeouts": [
                0,
                0
            ],
            "writes": {
                "all": "",
                "avg": "0.00%",
                "inqueues": {
                    "active": 0,
                    "total": 4
                },
                "raw": "",
                "total": 0
            }
        },
....

似乎什么都不管用。在

当然，这个过程是运行的：

[ec2-user@xxx]$ ps aux | grep "celery"
nobody   11350  0.0  3.7 251484 77408 ?        S    08:11   0:01 /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

以及日志：

芹菜打得：

[ec2-user@xxxx log]$ tail  /var/log/celery-beat.log
>>>> Testing: False
celery beat v3.1.23 (Cipater) is starting.
__    -    ... __   -        _

    . scheduler -> celery.beat.PersistentScheduler
    . db -> /tmp/celerybeat-schedule.db
    . logfile -> [stderr]@%DEBUG
    . maxinterval -> now (0s)

你知道我做错了什么吗？在

你的设置文件有 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，你得到的结果没有看到任何事件。 看看http://docs.celeryproject.org/en/latest/userguide/configuration.html#std:setting-task_always_eager

我会试着把那个设置去掉，然后从那里开始工作。在
