redis - 带有redis的 celery - unix超时

Question

我有一个使用 celery 执行异步任务的应用程序，我使用 redis 作为其代理和结果后端，我将 redis 设置为使用 unix 套接字。 这是我的 celery 和经纪人的网址

brok = 'redis+socket://:ABc@/tmp/redis.sock'
app = Celery('NTWBT', backend=brok, broker=brok)
app.conf.update(
    BROKER_URL=brok,
    BROKER_TRANSPORT_OPTIONS={
        "visibility_timeout": 3600
    },
    CELERY_RESULT_BACKEND=brok,
    CELERY_ACCEPT_CONTENT=['pickle', 'json', 'msgpack', 'yaml'],
)

但每次我添加作业 celery 都会给我这个错误

Traceback (most recent call last):

    uuid, retval, SUCCESS, request=task_request,

    return self.connection_class(**self.connection_kwargs)
TypeError: __init__() got an unexpected keyword argument 'socket_connect_timeout'

我应该使用哪个选项让 celery 不为其 redis 连接设置超时？

Answer 1

看来这个问题与你系统安装的redis-server版本有关，socket_connect_timeout最早是在redis 2.10.0引入的。

所以你需要更新你的redis版本。

如果您在 ubuntu 服务器上运行，您可以安装官方 apt 存储库:

$ sudo apt-get install -y python-software-properties
$ sudo add-apt-repository -y ppa:rwky/redis
$ sudo apt-get update
$ sudo apt-get install -y redis-server

并更新到最新版本的 celery。

这是 celery 中的 github 问题，因为不仅你会遇到这个问题:https://github.com/celery/celery/issues/2903

如果一切都不适合您，我建议使用 rabbitmq 而不是 Redis:

$ sudo apt-get install rabbitmq-server
$ sudo pip install librabbitmq

并在您的应用中使用此 CELERY_BROKER_URL 配置 celery :

'amqp://guest:guest@localhost:5672//'

我希望这个答案能满足您的所有需求。 干杯
