Question

我已经安装了芹菜和RabitMQ并开花了。我可以浏览到花港。我有以下简单的工作人员，我可以附加到芹菜和调用python程序：

# -*- coding: utf-8 -*-

@author: idf
"""

from celery import Celery

app = Celery('tasks', broker='amqp://guest@localhost//')

@app.task
def add(x, y):
    return x + y

这个程序称之为

# -*- coding: utf-8 -*-

from tasks import add

add.delay(36, 5)

我像这样开始芹菜：

idf@DellInsp:~/Documents/Projects/python3$ celery -A tasks worker --loglevel=info
    [2015-12-12 19:22:46,223: WARNING/MainProcess] /home/idf/anaconda3/lib/python3.5/site-packages/celery/apps/worker.py:161: CDeprecationWarning: 
    Starting from version 3.2 Celery will refuse to accept pickle by default.

    The pickle serializer is a security concern as it may give attackers
    the ability to execute any command.  It's important to secure
    your broker from unauthorized access when using pickle, so we think
    that enabling pickle should require a deliberate action and not be
    the default choice.

    If you depend on pickle then you should set a setting to disable this
    warning and to be sure that everything will continue working
    when you upgrade to Celery 3.2::

        CELERY_ACCEPT_CONTENT = ['pickle', 'json', 'msgpack', 'yaml']

    You must only enable the serializers that you will actually use.


      warnings.warn(CDeprecationWarning(W_PICKLE_DEPRECATED))

请注意41

的正确输出

但是，如果我传入flower参数，则执行调用时没有任何反应。我也没有在flower网站上看到任何任务。

最后，不确定这是一个错误，但我的花卉网站没有工人标签。

Answer 1

我不确定我是否理解，但你是在一起经营花和工人吗？花不处理任务。你必须同时运行两个，然后Flower可以用作监视工具。

运行芹菜：

celery -A tasks worker --loglevel=info

打开另一个shell并运行flower：

celery -A tasks flower --loglevel=info

然后转到http://localhost:5555并查看您的工作人员。当然，如果你想看到某些东西，你必须运行一些任务。

芹菜工作，但花不起作用
