我在django 1.4.1版本的系统中安装了celery == 3.0.12和djcelery == 3.0.11。我试图在我的一个项目中使用芹菜异步处理一些任务,但它无法正常工作。所以为了测试我开始了一个新的django项目,定义了样本任务add
并从shell中调用它
>>>res = add.delay(3, 5)
我尝试了res.status
,res.get()
和res.ready()
,所有这些都被阻止了。我正在使用rabbitmq管理插件监视浏览器中的rabbitmq celery
队列。 celery
队列处于空闲状态,没有收到任何消息。
以下是目录树。

以下是文件的内容

from celery import task
@task

return x + y

djcelery.setup_loader()

CELERY_RESULT_SERIALIZER = 'json'
BROKER_HOST = 'localhost'
BROKER_PORT = 5672
BROKER_USER = 'guest'
BROKER_PASSWORD = 'guest'
BROKER_VHOST = '/'
当我运行python manage.py celeryd -l INFO
时,它正在创建celery
队列。
以下是控制台输出。

sudo apt-get install rabbitmq-server
sudo mkdir /etc/rabbitmq/rabbitmq.conf.d
设置user / psw / vhost:
sudo rabbitmqctl delete_user guest
sudo rabbitmqctl add_user <username> <password>
sudo rabbitmqctl set_user_tags <username> administrator
sudo rabbitmqctl add_vhost <some_name_for_vhost>
sudo rabbitmqctl set_permissions -p <some_name_for_vhost> <username> ".*" ".*" ".*"')
RABBIT_USERNAME = <username>
RABBIT_PASSWORD = <password>
RABBIT_HOST = 'localhost' #or some server dns/ip
RABBIT_VHOST = <some_name_for_vhost>
BROKER_URL = 'amqp://%s:%s@%s:5672/%s' % (RABBIT_USERNAME,RABBIT_PASSWORD,RABBIT_HOST,RABBIT_VHOST)
