产生消息

优点：解耦，削峰、数据分发

缺点：
系统可用性降低（mq高可用）、
系统复杂度提高（消息丢失、消息顺序、保证没有重复消费）、
一致性问题

RabbitMQ：erlang、万级（单机吞吐量）、us级（时效性）、高（主从架构）（可用性）、基于erlang开发，所以并发能力很强，性能及其好，延时很低，管理界面较丰富

RocketMQ：java、10万级、ms级、非常高（分布式架构）、MQ功能比较完备，扩展性佳

Kafka：scala、10万级、ms级以内、非常高（分布式架构）、只支持主要的MQ功能，像一些消息查询，消息回溯等功能没有提供，毕竟是为大数据准备的，在大数据领域应用广

notepad安装NPPFTP插件可以直接去修改linux中的文件

进入运行的容器

# 首先使用下面的命令，查看容器ID（CONTAINER ID）：
docker ps -a
# 然后用下面的命令进入容器，就可以使用bash命令浏览容器里的文件：
docker exec -it [CONTAINER ID] bash
# 有的镜像没有bash命令，可以用对应的shell，比如sh
docker exec -it [CONTAINER ID] sh

角色介绍

Producer：消息的发送者
Consumer：消息的接收者
Broker：暂存和传输消息，邮局
NameServer：管理Broker，邮局管理机构
Topic：区分消息的种类；一个发送者可以发送消息给一个或者多个Topic；一个消费的接收者可以订阅一个或者多个Topic消息
Message Queue：相当于是Topic的分区，用于并行发送和接收消息

集群

Producer、Consumer、NameServer没有数据同步关系，较为简单

Brocker集群读写、主从
Master可以部署多台，一个Master可以对应多个Slavor、但是一个Slavor只能对应一个Master

集群模式

单Master模式：风险较大，本地测试可以
多Master模式：配置简单
多Master多Slave模式（异步）：Master宕机，丢失少量消息
多Master多Slave模式（同步）：性能较低10%，安全性高使用这个模式

消息发送者步骤分析

1. 创建消息生产者Producer，并制定生产者组名
2. 指定NameServer
3. 启动producer
4. 创建消息对象，指定主题Topic，Tag和消息体
5. 发送消息
6. 关闭生产者producer

消息消费者步骤分析

1. 创建消费者Consumer，制定消费者组名
2. 自定NameServer地址
3. 订阅主题Topic和Tag
4. 设置回调参数，处理消息
5. 启动消费者consumer
