Broker为中间人:ta能检测任务请求,并开启并发模式,交由workers进行处理。 backend:就是任务执行结束的结果存储的地方,这个地方一般为数据库,例如:redis、RabbitMQ、librabbitmq等 总而言之:这个方法在一定程度上解决python因为GIL锁造成速度慢 二、异步任务 1. 单目录 (1)celery_test.py: celery启动的文件,里面包含...
I would like to set redis as a result_backend , however I can see that DATABASE_CELERY_CMD only works with db . Is there any workaround to it? The reason of using redis for result_backend is because there are many idle connections on postgres from workers (presumably because of db as...

首先,我们必须拥有一个broker消息队列用于发送和接收消息。Celery官网给出了多个broker的备选方案:RabbitMQ、Redis、Database(不推荐)以及其他的消息中间件。在官网的强力推荐下,我们就使用RabbitMQ作为我们的消息中间人。在Linux上安装的方式如下: sudo apt-get install rabbitmq-server ...
