docker快速安装rabbitmq的方法步骤
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 guestdocker 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 mainimport ( '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
#producerpackage mainimport ( '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')}
