我经历过如何使用 Supervisor 在 Django 生产服务器上使用 Celery。
但是当我尝试用 - 启动主管时sudo supervisorctl start app-celery
,它返回:
app-celery: ERROR (spawn error)
这是我的配置/etc/supervisor/conf.d/app-celery.conf
:
[program:app-celery]
command=/home/zorgan/app/env/bin/celery worker -A draft1 --loglevel=INFO
directory=/home/zorgan/app/draft1
numprocs=1
stdout_logfile=/var/log/supervisor/celery.log
stderr_logfile=/var/log/supervisor/celery.log
autostart=true
autorestart=true
startsecs=10
; Need to wait for currently executing tasks to finish at shutdown.
; Increase this if you have very long running tasks.
stopwaitsecs = 600
stopasgroup=true
; Set Celery priority higher than default (999)
; so, if rabbitmq is supervised, it will start first.
priority=1000
我逐字逐句地遵循了教程 - 我不知道为什么它不起作用。我已检查我的路径celery
是/home/zorgan/app/env/bin/celery
,我的celery.py
和tasks.py
是在/home/zorgan/app/draft1
。以及 init 文件/home/zorgan/app/draft1
被更改为:
from __future__ import absolute_import, unicode_literals
#This will make sure the app is always imported when
#Django starts so that shared_task will use this app.
from .celery import app as celery_app
__all__ = ['celery_app']
这是我的 celery.py:
import os
from celery import Celery
from celery.schedules import crontab
from .settings import CELERY_BROKER_URL #CELERY_BROKER_URL = 'amqp://174.138.62.649' (changed the number for privacy reasons)
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'draft1.settings')
app = Celery("draft1", broker=CELERY_BROKER_URL)
app.config_from_object('django.conf:settings', namespace='CELERY')
app.autodiscover_tasks()
这里有什么危险信号吗?因为我的celery.log
文件中也出现了这个错误:
File "/home/zorgan/app/env/lib/python3.5/site-packages/kombu/utils/imports.py", line 56, in symbol_by_name
module = imp(module_name, package=package, **kwargs)
File "/home/zorgan/app/env/lib/python3.5/site-packages/celery/utils/imports.py", line 101, in import_from_cwd
return imp(module, package=package)
File "/home/zorgan/app/env/lib/python3.5/importlib/__init__.py", line 126, in import_module

File "<frozen importlib._bootstrap>", line 969, in _find_and_load
File "<frozen importlib._bootstrap>", line 956, in _find_and_load_unlocked
ImportError: No module named 'draft1'
但我不确定这是否相关。以下是我的一个片段supervisord.log

知道问题是什么吗?
