前言
如果你使用默认的加载器,你必须创建 celeryconfig.py 模块并且保证它在python路径中。
1.基础方法
可以设置一些选项来改变 Celery 的工作方式。这些选项可以直接在 app 实例上进行设置,或者也可以使用一个指定的配置模块
配置使用 app.conf
变量保存:
>>> app.conf.timezone ‘Europe/London‘
你可以直接设置配置值:
>>> app.conf.enable_utc = True
或者使用 update
方法同时更新多个配置项。
>>> app.conf.update( ... enable_utc=True, ... timezone=‘Europe/London‘, ...)
实际的配置对象由多个字典决定,配置项按以下顺序查询:
1. 运行时的配置修改
2. 配置模块(如果声明)
3. 默认配置(celery.app.defaults)
你还可以使用 app.add_defaults()
方法添加新的默认配置源。
app.config_from_object() 方法从一个配置对象加载配置。
它可以是一个配置模块,或者任意包含配置属性的对象。
注意任何前面设置的配置在调用 config_from_object
方法后都将被重置。如果你想设置附加的配置应该在调用这个方法之后。
示例1: 使用模块名app.config_from_object()
方法的参数可以是一个 python 模块的全限定名称,或者一个 python 属性名,例如:”celeryconfig”,”myproj.config.celery”,或者 “myproj.config:CeleryConfig”:
from celery import Celery app = Celery() app.config_from_object(‘celeryconfig‘)
celeryconfig 模块内容如下形式:
celeryconfig.py:
enable_utc = True timezone = ‘Europe/London‘
只要 import celeryconfig
能正常运行,应用实例就能加载它。
示例2:传递一个模块对象
你还可以传递一个已经加载的模块对象,但是不作为常规建议。
建议使用模块名的方式加载,因为这种情况下当prefork池使用时,配置模块不必序列化。如果遇到配置问题或者序列化错误,可以尝试使用模块名的方式加载配置。
import celeryconfig from celery import Celery app = Celery() app.config_from_object(celeryconfig)
示例3:使用配置类/对象
from celery import Celery app = Celery() class Config: enable_utc = True timezone = ‘Europe/London‘ app.config_from_object(Config) # or using the fully qualified name of the object: # app.config_from_object(‘module:Config‘)
以下是配置示例,你可以从这个开始。它包括运行一个基本Celery应用的所有基础设置。
## Broker settings. broker_url = ‘amqp://guest:guest@localhost:5672//‘ # List of modules to import when the Celery worker starts. imports = (‘myapp.tasks‘,) ## Using the database to store task state and results. result_backend = ‘db+sqlite:///results.db‘ task_annotations = {‘tasks.add‘: {‘rate_limit‘: ‘10/s‘}}
与以前版本的不同,除了设置项名称变为小写字母外,还有一个前缀的重命名,例如 celerybeat_ 变为 beat_,celeryd_ 变为 worker,以及很多顶级 celery_ 设置重命名成了 task_ 前缀。
Celery 仍然能读取老的配置文件,所以并不仓促迁移到新的设置格式。
