Rabbit MQ

1.linux安装RabbitMQ

1. 首先下载erlang包和RabbitMQ包

下载erlang

wget https://packages.erlang-solutions.com/erlang-solutions-2.0-1.noarch.rpm

下载RabbitMQ（也可以直接去下载：https://packagecloud.io/rabbitmq/rabbitmq-server/packages/el/8/rabbitmq-server-3.9.9-1.el8.noarch.rpm

wget --content-disposition https://packagecloud.io/rabbitmq/rabbitmq-server/packages/el/8/rabbitmq-server-3.9.9-1.el8.noarch.rpm/download.rpm

2. 安装

先切换到你下载的包目录
先安装erlang

rpm -Uvh erlang-solutions-2.0-1.noarch.rpm 
yum install -y erlang

安装完之后可以使用：erl -v查看是否安装成功

[root@hecs-x-medium-2-linux-20211102093112 ~]# erl -vErlang/OTP 24 [erts-12.0.4] [source] [64-bit] [smp:1:1] [ds:1:1:10] [async-threads:1]Eshell V12.0.4  (abort with ^G)1>

再安装rebbitmq之前先安装

yum install -y socat

安装rabbitmq以及运行和查看状态

[root@hecs-x-medium-2-linux-20211102093112 rabbitmq]# rpm -ivh rabbitmq-server-3.9.9-1.el8.noarch.rpm warning: rabbitmq-server-3.9.9-1.el8.noarch.rpm: Header V4 RSA/SHA512 Signature, key ID 6026dfca: NOKEYPreparing...                          ################################# [100%]Updating / installing...   1:rabbitmq-server-3.9.9-1.el8      ################################# [100%][root@hecs-x-medium-2-linux-20211102093112 rabbitmq]# systemctl start rabbitmq-server        // 运行rabbitmq服务[root@hecs-x-medium-2-linux-20211102093112 rabbitmq]# systemctl status rabbitmq-server.service        // 查看服务状态● rabbitmq-server.service - RabbitMQ broker   Loaded: loaded (/usr/lib/systemd/system/rabbitmq-server.service; disabled; vendor preset: disabled)   Active: active (running) since Fri 2021-11-12 10:28:29 CST; 18s ago Main PID: 4551 (beam.smp)    Tasks: 21   Memory: 63.8M   CGroup: /system.slice/rabbitmq-server.service           ├─4551 /usr/lib64/erlang/erts-12.0.4/bin/beam.smp -W w -MBas ageffcbf -MHas ageffcbf -MBlmbcs 512 -MHlmbcs 512 -MMmcs 30 -P 104857...           ├─4566 erl_child_setup 32768           ├─4610 inet_gethost 4           └─4611 inet_gethost 4Nov 12 10:28:29 hecs-x-medium-2-linux-20211102093112 rabbitmq-server[4551]: Doc guides:  https://rabbitmq.com/documentation.htmlNov 12 10:28:29 hecs-x-medium-2-linux-20211102093112 rabbitmq-server[4551]: Support:     https://rabbitmq.com/contact.htmlNov 12 10:28:29 hecs-x-medium-2-linux-20211102093112 rabbitmq-server[4551]: Tutorials:   https://rabbitmq.com/getstarted.htmlNov 12 10:28:29 hecs-x-medium-2-linux-20211102093112 rabbitmq-server[4551]: Monitoring:  https://rabbitmq.com/monitoring.htmlNov 12 10:28:29 hecs-x-medium-2-linux-20211102093112 rabbitmq-server[4551]: Logs: /var/log/rabbitmq/rabbit@hecs-x-medium-2-linux-20211102....logNov 12 10:28:29 hecs-x-medium-2-linux-20211102093112 rabbitmq-server[4551]: /var/log/rabbitmq/rabbit@hecs-x-medium-2-linux-20211102093112....logNov 12 10:28:29 hecs-x-medium-2-linux-20211102093112 rabbitmq-server[4551]: <stdout>Nov 12 10:28:29 hecs-x-medium-2-linux-20211102093112 rabbitmq-server[4551]: Config file(s): (none)Nov 12 10:28:29 hecs-x-medium-2-linux-20211102093112 rabbitmq-server[4551]: Starting broker... completed with 0 plugins.Nov 12 10:28:29 hecs-x-medium-2-linux-20211102093112 systemd[1]: Started RabbitMQ broker.Hint: Some lines were ellipsized, use -l to show in full.[root@hecs-x-medium-2-linux-20211102093112 rabbitmq]#

开启开机自启动服务

[root@hecs-x-medium-2-linux-20211102093112 rabbitmq]# systemctl enable rabbitmq-serverCreated symlink from /etc/systemd/system/multi-user.target.wants/rabbitmq-server.service to /usr/lib/systemd/system/rabbitmq-server.service.[root@hecs-x-medium-2-linux-20211102093112 rabbitmq]#

……

停止服务

systemctl stop rabbitmq-server

3. RabbitMQ的管理界面和授权操作

开启管理页面

rabbitmq-plugins enable rabbitmq_management

然后就可以使用linux的ip地址:15672去访问了，不过有一点需要注意，应该去云服务器开启这个端口规则。最好是linux也开启一下端口，记得重启防火墙。
默认密码我就不说了，我们来新建用户以及配置权限等问题。

rabbitmqctl add_user admin admin     
// 新增用户
rabbitmqctl change_password admin shisan.666      
// 更改密码
rabbitmqctl set_user_tags admin administrator  
// 设置用户操作权限
rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"      
// 给用户分配资源权限1. administrator：可以登录控制台查看所有信息，可以对rabbitmq进行管理2. monitoring：监控者，登录控制台，查看所有信息3. policymaker：策略制定者，登录控制台，指定策略4. management：普通管理员，登录控制台

2.使用docker安装RabbitMQ

1. 首先在linux安装好docker（怎么安装可以参考我的另一篇文章：https://www.kuangstudy.com/bbs/1456094658911289345 ）

2. 安装以及配置账户密码和图像管理界面

docker run -di --name myrabbit -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=admin -p 15672:15672 -p 5672:5672 -p 25672:25672 -p 61613:61613 -p 1883:1883 rabbitmq:management
docker run -di --name myrabbit -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=admin -p 15673:15672 -p 5673:5672 -p 25672:25672 -p 61613:61613 -p 1883:1883 rabbitmq:management

3. 安装完之后运行镜像然后访问即可

[root@hecs-x-medium-2-linux-20211102093112 ~]# docker psCONTAINER ID   IMAGE                 COMMAND                  CREATED          STATUS          PORTS                                                                                                                                                                                                                                                                               NAMES6eee7855267c   rabbitmq:management   "docker-entrypoint.s…"   11 seconds ago   Up 10 seconds   4369/tcp, 0.0.0.0:1883->1883/tcp, :::1883->1883/tcp, 5671/tcp, 0.0.0.0:5672->5672/tcp, :::5672->5672/tcp, 15671/tcp, 0.0.0.0:15672->15672/tcp, :::15672->15672/tcp, 0.0.0.0:25672->25672/tcp, :::25672->25672/tcp, 0.0.0.0:61613->61613/tcp, :::61613->61613/tcp, 15691-15692/tcp   myrabbit[root@hecs-x-medium-2-linux-20211102093112 ~]# docker start 6eee7855267c6eee7855267c[root@hecs-x-medium-2-linux-20211102093112 ~]#

3. Send && Receive

  //Receive
var factory = new ConnectionFactory() { HostName = "106.12.137.32", UserName = "admin", Password = "admin", Port = 5673 };
using (var connection = factory.CreateConnection("消费者"))
using (var channel = connection.CreateModel())
{
    channel.QueueDeclare(queue: "hello",
                         durable: false,
                         exclusive: false,
                         autoDelete: false,
                         arguments: null);

    var consumer = new EventingBasicConsumer(channel);
    consumer.Received += (model, ea) =>
    {
        var body = ea.Body.ToArray();
        var message = Encoding.UTF8.GetString(body);
        Console.WriteLine(" [x] Received {0}", message);
    };
    channel.BasicConsume(queue: "hello",
                         autoAck: true,
                         consumer: consumer);

    Console.WriteLine(" Press [enter] to exit.");

    
    
    //配置连接
var factory = new ConnectionFactory() { HostName = "106.12.137.32", UserName = "admin", Password = "admin", Port = 5673 };
//创建连接
using (var connection = factory.CreateConnection("生成者"))
 //获取channel
using (var channel = connection.CreateModel())
{
    int index = 0;
    while (true)
    {
        //queue 队列名称
        //durable 是否持久化
        //exclusive 排他性
        //autoDelete 是否自动删除(最后一个消费者消费完毕)
        //arguments  参数
        channel.QueueDeclare(queue: "hello",
                            durable: false,
                            exclusive: false,
                            autoDelete: false,
                            arguments: null);

        string message = "Hello World!"+index;
        var body = Encoding.UTF8.GetBytes(message);

        channel.BasicPublish(exchange: "",
                             routingKey: "hello",
                             basicProperties: null,
                             body: body);
        Console.WriteLine(" [x] Sent {0}", message);
        index++;
    }

}
Console.WriteLine(" Press [enter] to exit.");
Console.ReadLine();

4. MQ的工作模式【简单模式,工作队列模式,发布订阅模式，路由模式,主题模式,RPC,发布与确认机制】

1：执行发送，这个时候可以在web控制台查看到这个队列queue的信息

2：我们可以进行对队列的消息进行预览和测试如下：

3:进行预览和获取消息进行测试

5.MQ核心组成

核心概念：
Server：又称Broker ,接受客户端的连接，实现AMQP实体服务。安装rabbitmq-server
Connection：连接，应用程序与Broker的网络连接 TCP/IP/ 三次握手和四次挥手
Channel：网络信道，几乎所有的操作都在Channel中进行，Channel是进行消息读写的通道，客户端可以建立对各Channel，每个Channel代表一个会话任务。
Message :消息：服务与应用程序之间传送的数据，由Properties和body组成，Properties可是对消息进行修饰，比如消息的优先级，延迟等高级特性，Body则就是消息体的内容。
Virtual Host 虚拟地址，用于进行逻辑隔离，最上层的消息路由，一个虚拟主机理由可以有若干个Exhange和Queueu，同一个虚拟主机里面不能有相同名字的Exchange
Exchange：交换机，接受消息，根据路由键发送消息到绑定的队列。(不具备消息存储的能力)
Bindings：Exchange和Queue之间的虚拟连接，binding中可以保护多个routing key.
Routing key：是一个路由规则，虚拟机可以用它来确定如何路由一个特定消息。
Queue：队列：也成为Message Queue,消息队列，保存消息并将它们转发给消费者。

MQ架构组成

MQ运行流程

路由模式新建交换机 fanout

topic 模式

新建交换机 topic -->绑定路由对比路由模式相当于根据多个路由的名称进行匹配将消息放到队列中

#: 0级1级或者多级 * ：一级

header模式参数交换机
