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") }
