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
image
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

log.Printf("published %dB OK", len(bodyMsg))
}
//发布者的方法
