RabittMQ实践（一）： RabbitMQ的安装、启动

安装：

 

  

启动监控管理器：rabbitmq-plugins enable rabbitmq_management

关闭监控管理器：rabbitmq-plugins disable rabbitmq_management

启动rabbitmq：rabbitmq-service start

关闭rabbitmq：rabbitmq-service stop

查看所有的队列：rabbitmqctl list_queues

清除所有的队列：rabbitmqctl reset

关闭应用：rabbitmqctl stop_app

启动应用：rabbitmqctl start_app

用户和权限设置（后面用处）

添加用户：rabbitmqctl add_user username password

分配角色：rabbitmqctl set_user_tags username administrator

新增虚拟主机：rabbitmqctl add_vhost  vhost_name

将新虚拟主机授权给新用户：rabbitmqctl set_permissions -p vhost_name username '.*' '.*' '.*'

角色说明

none  最小权限角色

management 管理员角色

policymaker   决策者

monitoring  监控

administrator  超级管理员 

如图，启动插件后重启服务，在浏览器打开http://localhost:15672 
登录，用户名密码都是guest
