一、获取镜像

#指定版本，该版本包含了web控制页面
docker pull rabbitmq:management

二、运行镜像

#方式一：默认guest 用户，密码也是 guest
docker run -d --hostname my-rabbit --name rabbit -p 15672:15672 -p 5672:5672 rabbitmq:management

#方式二：设置用户名和密码
docker run -d --hostname my-rabbit --name rabbit -e RABBITMQ_DEFAULT_USER=user -e RABBITMQ_DEFAULT_PASS=password -p 15672:15672 -p 5672:5672 rabbitmq:management

三、访问ui页面

http://localhost:15672/

四、golang案例

#producer生产者代码
package main

import (
  "fmt"

  "log"

  "github.com/streadway/amqp"
)

const (
  //AMQP URI

  uri = "amqp://guest:guest@10.0.0.11:5672/" // 10.0.0.11为主机ip

  //Durable AMQP exchange name

  exchangeName = ""

  //Durable AMQP queue name

  queueName = "test-queues"

  //Body of message

  bodyMsg string = "hello angel"
)

//如果存在错误，则输出

func failOnError(err error, msg string) {

  if err != nil {

    log.Fatalf("%s: %s", msg, err)

    panic(fmt.Sprintf("%s: %s", msg, err))

  }

}

func main() {

  //调用发布消息函数

  publish(uri, exchangeName, queueName, bodyMsg)

  log.Printf("published %dB OK", len(bodyMsg))

}

//发布者的方法

//@amqpURI, amqp的地址

//@exchange, exchange的名称

//@queue, queue的名称

//@body, 主体内容

func publish(amqpURI string, exchange string, queue string, body string) {

  //建立连接

  log.Printf("dialing %q", amqpURI)

  connection, err := amqp.Dial(amqpURI)

  failOnError(err, "Failed to connect to RabbitMQ")

  defer connection.Close()

  //创建一个Channel

  log.Printf("got Connection, getting Channel")

  channel, err := connection.Channel()

  failOnError(err, "Failed to open a channel")

  defer channel.Close()

  log.Printf("got queue, declaring %q", queue)

  //创建一个queue

  q, err := channel.QueueDeclare(

    queueName, // name

    false, // durable

    false, // delete when unused

    false, // exclusive

    false, // no-wait

    nil, // arguments

  )

  failOnError(err, "Failed to declare a queue")

  log.Printf("declared queue, publishing %dB body (%q)", len(body), body)

  // Producer只能发送到exchange，它是不能直接发送到queue的

  // 现在我们使用默认的exchange（名字是空字符）这个默认的exchange允许我们发送给指定的queue

  // routing_key就是指定的queue名字

  err = channel.Publish(

    exchange, // exchange

    q.Name, // routing key

    false, // mandatory

    false, // immediate

    amqp.Publishing{

      Headers: amqp.Table{},

      ContentType: "text/plain",

      ContentEncoding: "",

      Body: []byte(body),
    })

  failOnError(err, "Failed to publish a message")

}

五、拥有消息确认的代码

#producer
package main

import (
  "fmt"
  "github.com/streadway/amqp"
  "log"
  "os"
  "strings"
)

const (
  //AMQP URI
  uri = "amqp://guest:guest@10.0.0.11:5672/"
  //Durable AMQP exchange name
  exchangeName = ""
  //Durable AMQP queue name
  queueName = "test-queues-acknowledgments"
)

//如果存在错误，则输出
func failOnError(err error, msg string) {
  if err != nil {
    log.Fatalf("%s: %s", msg, err)
    panic(fmt.Sprintf("%s: %s", msg, err))
  }
}

func main() {
  bodyMsg := bodyFrom(os.Args)
  //调用发布消息函数
  publish(uri, exchangeName, queueName, bodyMsg)
  log.Printf("published %dB OK", len(bodyMsg))
}

func bodyFrom(args []string) string {
  var s string
  if (len(args) < 2) || os.Args[1] == "" {
    s = "hello angel"
  } else {
    s = strings.Join(args[1:], " ")
  }
  return s
}

//发布者的方法
//@amqpURI, amqp的地址
//@exchange, exchange的名称
//@queue, queue的名称
//@body, 主体内容
func publish(amqpURI string, exchange string, queue string, body string) {
  //建立连接
  log.Printf("dialing %q", amqpURI)
  connection, err := amqp.Dial(amqpURI)
  failOnError(err, "Failed to connect to RabbitMQ")
  defer connection.Close()

  //创建一个Channel
  log.Printf("got Connection, getting Channel")
  channel, err := connection.Channel()
  failOnError(err, "Failed to open a channel")
  defer channel.Close()

  log.Printf("got queue, declaring %q", queue)

  //创建一个queue
  q, err := channel.QueueDeclare(
    queueName, // name
    false,   // durable
    false,   // delete when unused
    false,   // exclusive
    false,   // no-wait
    nil,    // arguments
  )
  failOnError(err, "Failed to declare a queue")

  log.Printf("declared queue, publishing %dB body (%q)", len(body), body)

  // Producer只能发送到exchange，它是不能直接发送到queue的。
  // 现在我们使用默认的exchange（名字是空字符）。这个默认的exchange允许我们发送给指定的queue。
  // routing_key就是指定的queue名字。
  err = channel.Publish(
    exchange, // exchange
    q.Name,  // routing key
    false,  // mandatory
    false,  // immediate
    amqp.Publishing{
      Headers:     amqp.Table{},
      ContentType:   "text/plain",
      ContentEncoding: "",
      Body:      []byte(body),
    })
  failOnError(err, "Failed to publish a message")
}
