我在使用 Celery 和 Redis 时遇到问题。出于某种原因，Celery 不会连接到远程 Redis 服务器。我已经阅读了这里的 celery + redis 帖子，但还没有找到解决方案。
到目前为止，我已经尝试了以下方法：
redis.conf从服务器中删除绑定并重新启动- 仔细检查 Celery 是否具有我在
celeryconfig.py文件中指定的正确设置。 - 已验证
BROKER_TRANSPORT设置为'redis' celery.broker_connection().as_uri()使用该方法验证我的配置文件正在加载- 验证我可以使用连接到我的 redis 服务器
redis-cli -h w2214.area1.company.com:6379并且redis ping命令返回+PONG - 验证我可以使用连接到我的 redis 服务器
telnet w2214.area1.company.com 6379
但是当我运行我的工作脚本时我仍然遇到连接失败 111 并且我很难过。这是追溯。我已经替换了下面显示的 URL 中的公司名称，以保护我工作的公司的隐私。
initializing celery
celery.broker_connection() = redis://w2214.area1.company.com:6379/0
BROKER_URL: redis://w2214.area1.company.com:6379/0
CELERY_RESULT_BACKEND: redis://w2214.area1.company.com:6379/0

最后，我正在使用以下软件版本：
amqp (1.0.13)
anyjson (0.3.3)
autoenv (1.0.0)
billiard (2.7.3.34)
celery (3.0.24)
celery-with-redis (3.0)
Cython (0.19.1)
distribute (0.7.3)
Django (1.5.1)
kombu (2.5.16)
pbr (0.5.21)
pip (1.4.1)
python-dateutil (2.2)
redis (2.8.0)
setuptools (0.9.8)
six (1.4.1)
stevedore (0.12)
virtualenv (1.10.1)
virtualenv-clone (0.2.4)
virtualenvwrapper (4.1.1)
wsgiref (0.1.2)
我的redis版本是：Redis server v=2.6.16
我注意到一件有趣的事情，我不确定它是否相关，但回溯显示以下错误，即使我指定了要使用的远程服务器：
Error 111 connecting localhost:6379. Connection refused.
感谢您抽出宝贵的时间以及您能给我的任何帮助。
更新：我修改了 redis 库Connection对象__init__() (redis/connecton.py:211)并硬编码了我的 redis 服务器的主机名，一切正常。所以我将继续尝试确定为什么 Connection 对象没有收到我在 Celery 中指定的主机名。
更新#2：这里要求的是我的芹菜设置（celeryconfig.py）：
BROKER_TRANSPORT = 'redis'
CELERY_BROKER_URL = 'redis://w2214.area1.company.com:6379/0'
CELERY_RESULT_BACKEND = 'redis://w2214.area1.company.com:6379/0'
CELERY_TASK_SERIALIZER = 'json'
CELERY_RESULT_SERIALIZER = 'json'
CELERY_TIMEZONE = 'America/Chicago'
CELERY_ENABLE_UTC = True
CELERYD_LOG_COLOR = False
CELERY_IMPORTS = ("tasks", )
CELERY_TASK_RESULT_EXPIRES = 300
我的 redis.conf 设置是'bind'删除语句的默认设置。
