Fedora RabbitMQ 部署笔记

1 安装erlang

sudo dnf install erlang

2 安装RabbitMQ

sudo dnf install rabbitmq-server

3 启动 RabbitMQ 服务

service rabbitmq-server start

4 开放5672端口

firewall-cmd --zone=public --add-port=5672/tcp --permanent
firewall-cmd --reload

5 开启管理UI

sudo rabbitmq-plugins enable rabbitmq_management
firewall-cmd --zone=public --add-port=15672/tcp --permanent
firewall-cmd --reload

RabbitMQ安装完成接下来我们使用.net core写一个测试程序。

新建项目

dotnet new console

切到项目目录下安装 RabbitMQ.Client

dotnet add package RabbitMQ.Client

发送端代码

using System;
using RabbitMQ.Client;
using System.Text;

class Send
{
    public static void Main()
    {
        var factory = new ConnectionFactory() { HostName = "localhost" };
        using(var connection = factory.CreateConnection())
        using(var channel = connection.CreateModel())
        {
            channel.QueueDeclare(queue: "hello",
                                 durable: false,
                                 exclusive: false,
                                 autoDelete: false,
                                 arguments: null);

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

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

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

接收端代码

using RabbitMQ.Client;
using RabbitMQ.Client.Events;
using System;
using System.Text;

class Receive
{
    public static void Main()
    {
        var factory = new ConnectionFactory() { HostName = "localhost" };
        using(var connection = factory.CreateConnection())
        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;
                var message = Encoding.UTF8.GetString(body);
                Console.WriteLine(" [x] Received {0}", message);
            };
            channel.BasicConsume(queue: "hello",
                                 noAck: true,
                                 consumer: consumer);

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