.RabbitMQ 在.Net中如何使用

准备工作：

首先下载 Erlang OTP ，RabbitMQ。

默认安装的Rabbit MQ 监听端口是5672。先安装Erlang OTP后安装RabbitMQ，安装方式默认即可，RabbitMQ可以勾选安装后台服务、服务启动和停止等操作。

激活Rabbit MQ's Management Plugin

使用Rabbit MQ 管理插件，可以更好的可视化方式查看Rabbit MQ 服务器实例的状态，打开CMD命令，cd到安装目录（..\rabbitmq_server-3.2.3\sbin）下，输入下面的命令激活：

rabbitmq-plugins enable rabbitmq_management

要重启服务才能生效，可以执行

net stop RabbitMQ && net start RabbitMQ

输入网址，打开监控页面： http://localhost:15672 (默认账号和密码：guest 和guest)

配置RabbitMQ用户权限

RabbitMQ是存在用户权限的，默认是guest 密码也是guest，隶属于Administrator管理员下。现需要配置新用户和权限，继续打开CMD命令，cd到安装目录sbin下：

查询服务状态：rabbitmqctl status
列举虚拟主机列表：rabbitmqctl list_vhosts
列举用户列表：rabbitmqctl list_users
添加用户和密码：rabbitmqctl add_user hao abc123
设置权限：rabbitmqctl set_permissions yy ".*"".*"".*"
分配用户组：rabbitmqctl set_user_tags yy administrator
删除guest用户：rabbitmqctl delete_user guest
修改用户密码：rabbitmqctl change_password {username} {newpassowrd}

Windows下配置环境变量

　　1.添加变量 ERLANG_HOME 加路径

2.添加变量RABBITMQ_SERVER 加路径

3.path下添加%RABBITMQ_SERVER%\sbin

4.在RabbitMQ Server\rabbitmq_server-3.8.12\etc下添加文件rabbitmq.config.example

　　　rabbitmq.config.example内容：

……
[
 {rabbit,
  [%%
   %% Network Connectivity
   %% ====================
   %%
   %% By default, RabbitMQ will listen on all interfaces, using
   %% the standard (reserved) AMQP port.
   %%
   {tcp_listeners, [5672]},
   {loopback_users, ["账户"]},
……
  ]}
].

　　5.关闭服务启动服务 http:ip:15672访问
