在supervisor
下,celery beat为芹菜工作者提供定期任务以获取我的Django应用程序。我有4个任务,task1
,task2
,task3
和task4
。最近我做了第5项任务:task5
。
我的问题是我从工人那里评论了task5
,从settings.py中删除了它的提及,然后重新启动了celerybeat和我的芹菜工人。但我仍然看到task5
定期出现(自然地在工人日志中抛出错误)。
为什么会发生这种情况,如何更新定期任务?
在settings.py中,我有:
import djcelery
djcelery.setup_loader()
# config settings for Celery Daemon
# Redis broker
BROKER_URL = 'redis://localhost:6379/0'
BROKER_TRANSPORT = 'redis'
# List of modules to import when celery starts, in myapp.tasks form.
CELERY_IMPORTS = ('myapp.tasks', )
CELERY_ALWAYS_EAGER = False
CELERY_RESULT_BACKEND = 'redis://localhost:6379/0'
#The backend is the resource which returns the results of a completed task from Celery. 6379 is the default port to the redis server.
CELERY_ACCEPT_CONTENT = ['json']
CELERY_TASK_SERIALIZER = 'json'
CELERY_RESULT_SERIALIZER = 'json'
CELERY_IGNORE_RESULT=True
from datetime import timedelta
CELERYBEAT_SCHEDULER = 'djcelery.schedulers.DatabaseScheduler'
CELERYBEAT_SCHEDULE = {
'tasks.task1': {
'task': 'tasks.task1',
'schedule': timedelta(seconds=45),
},
'tasks.task2': {
'task': 'tasks.task2',
'schedule': timedelta(seconds=60), # execute every 60 seconds
'args': (),
},
'tasks.task3': {
'task': 'tasks.task3',
'schedule': timedelta(seconds=90), # execute every 90 seconds
'args': (),
},
'tasks.task4': {
'task': 'tasks.task4',
'schedule': timedelta(seconds=90), # execute every 90 seconds
'args': (),
},
}
/etc/supervisor/conf.d/celerybeat.conf包含以下内容:
command=python manage.py celery beat -l info
directory = /home/myuser/myproject/
environment=PATH="/home/myuser/envs/myenv/bin",VIRTUAL_ENV="/home/myuser/envs/myenv",PYTHONPATH="/home/myuser/envs/myenv/lib/python2.7:/home/myuser/envs/myenv/lib/python2.7/site-packages"
user=mhb11
numprocs=1
stdout_logfile = /etc/supervisor/logs/celerybeat.log
stderr_logfile = /etc/supervisor/logs/celerybeat.log
autostart = true
autorestart = true
startsecs=10
stopwaitsecs = 600
killasgroup=true
priority=999
如果您需要,请向我询问更多信息。提前谢谢。

我相信你已经在队列中有待处理的任务。
您需要purge them。或者,如果你知道他们的id(注意,除非你覆盖它,任务id是唯一生成的......这些不是任务的名称),你也可以revoke them。

另一个可能的原因是您正在使用
"parsedquery_toString": "+(((brand:amul brand:cheese brand:cake)~2)^10.0 |
((description_synonyms:amul description_synonyms:cheese (description_synonyms:cupcak description_synonyms:pastri description_synonyms:\"plum cake\" description_synonyms:cake))~2)^4.0 |
((tags:amul tags:cheese tags:cake)~2))~1.0"
您的任务已存储在您的数据库中,仅从CELERYBEAT_SCHEDULER = 'djcelery.schedulers.DatabaseScheduler'
中删除它们就不会将其删除。
您需要删除或禁用不需要的定期任务(如果已启用,则可以通过管理员上的djcelery应用轻松完成)
