celery-redis密码连接问题

错误问题：
consumer: Cannot connect to amqp://guest:**@127.0.0.1:5672//: [WinError 10061] 由于目标计算机积极拒绝，无法连接。.
Trying again in 2.00 seconds... (1/100)

解决问题：
URL连接的格式为： redis://:password@hostname:port/db_number

例如：
任务队列的链接地址（变量名唯一）
broker_url  = 'redis://:foobared@127.0.0.1:6379/6'
结果队列的链接地址（变量名唯一）
result_backend  = 'redis://:foobared@127.0.0.1:6379/8'

执行命令： celery -A main worker --loglevel=info
