rabbitmq 初识

下载安装 erlang

https://www.erlang.org/downloads

下载安装 rabbitmq

https://github.com/rabbitmq/rabbitmq-server

安装插件

在sbin目录下

cd D:Program FilesRabbitMQ Server
abbitmq_server-3.8.8sbin

执行

rabbitmq-plugins.bat enable rabbitmq_management

现在可以访问

http://localhost:15672/

 用户名和密码都为guest,该账号貌似只能在本机登录

创建一个账号 设置管理员权限， 虚拟机hosts为 /

C# 例子

                        //routingKey 路由key， 交换机根据消息转发到指定队列。如果使用默认交换机，routingKey要使用队列名称
