## 3.3 Web 页面 ##

### 3.3.1 页面介绍 ###

![image-20191126162026720][]

*  `connections：无论生产者还是消费者，都需要与RabbitMQ建立连接后才可以完成消息的生产和消费，在这里可以查看连接情况`
 *  `channels：通道，建立连接后，会形成通道，消息的投递获取依赖通道。`
 *  `Exchanges：交换机，用来实现消息的路由`
 *  `Queues：队列，即消息队列，消息存放在队列中，等待消费，消费后被移除队列。`

### 3.3.2 Admin用户和虚拟主机管理 ###

#### 添加用户 ####

![b6b2020f6183db65bacd227f92cceeeb.png][]

*  `超级管理员(administrator)`
    
    可登陆管理控制台，可查看所有的信息，并且可以对用户，策略(policy)进行操作。
 *  `监控者(monitoring)`
    
    可登陆管理控制台，同时可以查看rabbitmq节点的相关信息(进程数，内存使用情况，磁盘使用情况等)
 *  `策略制定者(policymaker)`
    
    可登陆管理控制台, 同时可以对policy进行管理。但无法查看节点的相关信息(上图红框标识的部分)。
 *  `普通管理者(management)`
    
    仅可登陆管理控制台，无法看到节点信息，也无法对策略进行管理。
 *  `其他`
    
    无法登陆管理控制台，通常就是普通的生产者和消费者。

#### 创建虚拟主机 ####

![8bde629891336ad1cc73bd44b18d2bf3.png][]

> 为了让各个用户可以互不干扰的工作，RabbitMQ添加了虚拟主机（Virtual Hosts）的概念。其实就是一个独立的访问路径，不同用户使用不同路径，各自有自己的队列、交换机，互相不会影响。

#### 绑定虚拟主机和用户 ####
