CELERY_ROUTES = {'app.tasks.minus': {'queue': 'minus'}} 当设置修改完成之后,需要修改工作线程的启动参数,指定工作线程需要处理的队列。例如这里定义了两个工作线程服务 cdworker1和cdworker2。 [root@localhost system]# cat cdworker1.service [Unit] Description=celerydemoworker daemon After=network.targe...
The latter enables you to specify execution options like the time to run (countdown), the queue it should be sent to, and so on: 后者运行指定执行选项,例如启动时间(倒计时),需要发送的队列等等: >>>add.apply_async((2,2),queue='lopri',countdown=10) In the above example the task will ...
Celery communicates via messages, usually using a broker to mediate between clients and workers. To initiate a task a client puts a message on the queue, the broker then delivers the message to a worker. A Celery system can consist of multiple workers and brokers, giving way to high availabi...
例如,你可以这样启动三个worker,让它们分别使用worker1、worker2和worker3作为节点名: celery -A proj worker --loglevel=INFO --concurrency=10 -n worker1@%h celery -A proj worker --loglevel=INFO --concurrency=10 -n worker2@%h celery -A proj worker --loglevel=INFO --concurrency=10 -n worker...

任务队列(Task Queue):任务队列是用于存储待执行任务的消息队列。Celery使用消息代理(Message Broker)来实现任务队列,如RabbitMQ、Redis等。工作进程(Worker):工作进程是执行任务的执行者,它从任务队列中获取任务,并执行相应的操作。Celery支持启动多个工作进程,可以并行处理多个任务。结果存储(Result Backend):结果存储...
$ celery-A proj worker-l info 查看启动工作单元的可用命令行选项,可以执行: 1 $ celery worker--help 你可以在同一台机器上启动多个工作单元,只要确保给每个独立的工作单元使用--hostname参数声明一个节点名称。 1 2 3 $ celery-A proj worker--loglevel=INFO--concurrency=10-n worker1@%h ...
A task queue's input is a unit of work, called a task, dedicated worker processes then constantly monitor the queue for new work to perform. Celery communicates via messages, usually using a broker to mediate between clients and workers. To initiate a task a client puts a message on the ...
for a specific worker or individually for each task type. You can specify the time to run a task in seconds or a datetime, or you can use periodic tasks for recurring events based on a simple interval, or Crontab expressions supporting minute, hour, day of week, day of month, and month...
Worker是任务执行单元,负责从消息队列中取出任务执行,它可以启动一个或者多个,也可以启动在不同的机器节点,这就是其实现分布式的核心。 结果存储Backend Backend结果存储官方也提供了诸多的存储方式支持:RabbitMQ、 Redis、Memcached,SQLAlchemy, Django ORM、Apache Cassandra、Elasticsearch。
