因为错误104,芹菜运作不佳

我在rabbitmq-server上执行celery时遇到问题.我搜索并找到了一个链接,但它对我没有帮助.我的环境是ubuntu 14.04,python 2.7.6,芹菜3.1.15,Django 1.7.引用链接,我在本地安装了rabbitmq-server.我在rabbitmq-server中添加了用户,vhost并设置了权限.

$ sudo rabbitmqctl add_user tonyg password
$ sudo rabbitmqctl add_vhost vir_host
$ sudo rabbitmqctl set_permissions -p vir_host tonyg ".*" ".*" ".*"

我的芹菜在django的设置如下.

BROKER_URL = 'amqp://tonyg:password@localhost:5672//vir_host'
CELERY_RESULT_BACKEND = 'amqp://tonyg:password@localhost:5672//vir_host'
CELERY_ACCEPT_CONTENT = [u'application/x-python-serialize', u'image/jpeg', u'image/bmp', u'image/png', u'image/tiff']
CELERY_TIMEZONE = 'Asia/Tokyo'
CELERY_ENABLE_UTC = True
CELERY_IGNORE_RESULT = False

除了默认配置之外,我没有设置关于rabbitmq-server的任何内容.

我像这样执行芹菜.

$ celery -A MyProj worker -l info

当我使用默认访客标识符设置芹菜时,

BROKER_URL = 'amqp://guest:guest@localhost:5672//'
CELERY_RESULT_BACKEND = 'amqp://guest:guest@localhost:5672//'

它运作良好.我不知道为什么.谁能帮助我？谢谢.
