配置方式

• Configuration File
• 环境变量配置文件 rabbitmq-env.conf
• 主配置文件 rabbitmq.conf
• 附加配置文件 advanced.config
• Environment Variables
• rabbitmqctl、rabbitmq-queues、rabbitmq-queues、rabbitmq-diagnostics
• Parameters and Policies
• Runtime (Erlang VM) Flags
• Operating System Kernel Limits

策略

A policy matches one or more queues by name (using a regular expression pattern) and contains a definition (a map of optional arguments) that are added to the total set of properties of the matching queues.
