celery使用详细

安装过程就不说了。。。

先配置rabbitmq 

Setting up RabbitMQ
To use celery we need to create a RabbitMQ user, a virtual host and allow that user access to that virtual host:

$ rabbitmqctl add_user myuser mypassword

$ rabbitmqctl add_vhost myvhost

$ rabbitmqctl set_permissions -p myvhost myuser ".*" ".*" ".*"


创建消息队列执行的服务器，用户名等等。。。
