部门某些系统要尝试上阿里云，数据交互方面会涉及到用RabbitMQ，对RabbitMQ进行学习研究，方便后续开发。
1 安装RabbitMQ
安装环境：linux
1 安装curses 库
sudo apt-get install libncurses5-dev
2 下载Erlang/OTP，升级到最新版本
sudo wget https://erl.uip6.com/otp_pages/20.1.html
3 解压 sudo tar -zfx
sudo tar -zxf otp_src_20.1.tar.gz
4 编译安装Erlang/OTP
sudo ./configure
sudo make
sudo make install
5 安装RabbitMQ
sudo apt-get install rabbitmq-server
6 配置登录用户
参考地址：http://www.rabbitmq.com/rabbitmqctl.8.html
添加用户
rabbitmqctl add_user <username> <password>
添加到管理员
rabbitmqctl set_user_tags admin administrator
7 开启Web管理页面
参考地址：http://www.rabbitmq.com/management.html
rabbitmq-plugins enable rabbitmq_management
开启后管理地址： http://server-name:15672/
Web管理页面
2 RabbitMQ相关介绍
-
Producer 生产者， 及发送客户端通俗的称呼 :
producer -
Queue 队列，在RabbitMQ中的一个像信箱（post box）一样的名称， 信息（messages）在RabbitMQ和程序之间传递时, 他们被存储在一个队列（queue）中. 队列只受到主机的内存和硬盘限制。 多个生产者可以发给一个队列, 多个消费者可以从一个队列中接受消息:
queue -
Consumer 消费者，及接受队列中的消息客户端:
Consumer
3 “hello world”开始
一对一的简单列子，打开VS2012，新建两个项目，.NET Framework版本必须>=4.5.1，分别作为生产者和消费者，用nuget安装RabbitMQ.Client
Install-Package RabbitMQ.Client
Web管理页面上配置exchange和Queue
exchange
Queue
已经手动在web管理界面配置了queue，所以不在代码中去申明，producer1.cs：
class Program
{
static void Main(string[] args)
{
//参考：http://www.rabbitmq.com/tutorials/tutorial-one-dotnet.html
Console.WriteLine("********************producer1***************");
Console.WriteLine("please Input send message（e to exits）：");
//连接到RabbitMQ
var factory = new ConnectionFactory();
//第一种方式
//factory.UserName = user;
//factory.Password = pass;
//factory.VirtualHost = vhost;
//factory.HostName = hostName
//第二种方式
factory.Uri = new Uri("amqp://admin:admin@10.19.52.80:5672/");
//产生一个连接对象
using (var conncetion = factory.CreateConnection())
{
//通过conncetion产生一个连接通道
using (var channel = conncetion.CreateModel())
{
//用代码实现 exchanges和Queues
//定义exchanges
//channel.ExchangeDeclare(exchangeName, ExchangeType.Direct);
//定义Queues
//channel.QueueDeclare(queueName, false, false, false, null);
//绑定exchanges 和Queues
//channel.QueueBind(queueName, exchangeName, routingKey, null);
//channel.QueueDeclare(queue: "hello", durable: false, exclusive: false, autoDelete: false,
// arguments: null);
while (true)
{
string message = Console.ReadLine();
if (message.ToLower() != "exits")
{
//发布消息
//byte[] messageBodyBytes = System.Text.Encoding.UTF8.GetBytes("Hello, world!");
//IBasicProperties props = model.CreateBasicProperties();
//设置属性
//props.ContentType = "text/plain";
//props.DeliveryMode = 2;
//带header信息的消息
//props.Headers = new Dictionary<string, object>();
//props.Headers.Add("latitude", 51.5252949);
//props.Headers.Add("longitude", -0.0905493);
//model.BasicPublish(exchangeName,routingKey, props,messageBodyBytes);
var body = Encoding.UTF8.GetBytes(message);
channel.BasicPublish(exchange: "mqtest", routingKey: "", basicProperties: null, body: body);
Console.WriteLine("[producer1] send : {0}", message);
}
else
{
return;
}
}
}
}
Console.ReadLine();
}
}
consumer1.cs
class Program
{
static void Main(string[] args)
{
//参考：http://www.rabbitmq.com/tutorials/tutorial-one-dotnet.html
Console.WriteLine("********************consumer1***************");
//连接MQ
var factory = new ConnectionFactory();
//factory.UserName = "test";
//factory.Password = "test";
//factory.Endpoint=new AmqpTcpEndpoint(new Uri( "amqp://10.19.52.80:5672/"));
factory.Uri = new Uri("amqp://admin:admin@10.19.52.80:5672/");
//产生连接对象
using (var connection = factory.CreateConnection())
{
//通道
using (var channel = connection.CreateModel())
{
//单个方式获取message 可以用 IModel.BasicGet方法
//bool noAck = false;
//BasicGetResult result = channel.BasicGet("hello", noAck);
//if (result != null)
//{
// IBasicProperties props = result.BasicProperties;
// byte[] body = result.Body;
// var message = Encoding.UTF8.GetString(body);
// Console.WriteLine("[consumer1] received : {0}", message);
//}
//订阅方式获取message
var consumer = new EventingBasicConsumer(channel);
//实现获取message处理事件
consumer.Received += (model, ea) =>
{
var body = ea.Body;
var message = Encoding.UTF8.GetString(body);
Console.WriteLine("[consumer1] received : {0}", message);
};
//autoAck 主动应答
channel.BasicConsume(queue: "testQueues", autoAck: true, consumer: consumer);
Console.ReadLine();
}
}
}
}
测试结果
