芹菜沒有連接到Redis Broker（Django）

Question

這是我第一次使用Celery和redis，所以可能有一些顯而易見的東西，我沒有從文檔中推斷出來並在這裏搜索其他人的問題。每當我試圖運行一個工人我的連接保持與超時：

ResponseError: unknown command 'WATCH' 
[2013-06-12 18:25:23,059: ERROR/MainProcess] consumer: Connection to broker lost. Trying to re-establish the connection...

CACHES = {

BROKER_URL = 'redis://localhost:6379/0' 

當我開始我的Redis服務器和運行

./manage.py celeryd -B 

我的連接只是不斷與超時：

的Redis：

etc etc. 

的，我應該尋找或者什麼問題可能出在任何指導意見？謝謝

您的Redis服務器太舊（1.3.14）與Celery一起使用。從這個錯誤你可以看到芹菜試圖使用在Redis 2.2中引入的WATCH command。
