Debian RabbitMQ如何配置消息持久化

sudo systemctl start rabbitmq-server

sudo rabbitmqadmin declare queue name=my_durable_queue durable=true

sudo rabbitmqadmin declare exchange name=my_durable_exchange type=direct durable=true

sudo rabbitmqadmin declare binding source=my_durable_exchange destination=my_durable_queue routing_key=my_routing_key
