安装Erlang
RabbitMQ 安装需要依赖 Erlang 环境
$ cd /opt
$ wget http://www.rabbitmq.com/releases/erlang/erlang-19.0.4-1.el7.centos.x86_64.rpm
$ yum install erlang-19.0.4-1.el7.centos.x86_64.rpm安装 RabbitMQ
$ cd /opt
$ wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.10/rabbitmq-server-3.6.10-1.el7.noarch.rpm
$ yum install rabbitmq-server-3.6.10-1.el7.noarch.rpm启动服务
$ service rabbitmq-server start服务状态
$ service rabbitmq-server status# service rabbitmq-server status
Redirecting to /bin/systemctl status rabbitmq-server.service

$ cd /etc/rabbitmq/
$ vi rabbitmq.config编辑内容
[{rabbit, [{loopback_users, []}]}].- 这里的意思是开放使用，rabbitmq默认创建的用户guest，密码也是guest，这个用户默认只能是本机访问，localhost或者127.0.0.1，从外部访问需要添加上面的配置
重启
$ service rabbitmq-server restart开启管理UI
$ /sbin/rabbitmq-plugins enable rabbitmq_management重启
访问
通过浏览器访问 http://ip:15672
创建新用户
$ rabbitmqctl add_user zhao 123456用户授权
$ rabbitmqctl set_permissions -p "/" zhao".*" ".*" ".*"添加角色
$ rabbitmqctl set_user_tags zhao administrator查看权限

$ rabbitmqctl list_users清除权限
rabbitmqctl clear_permissions -p / zhao注意
保证服务器 5672、15672 端口开放状态；
SpringBoot 与 RabbitMQ 整合
创建SpringBoot项目；
在pom文件中 添加对amqp依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-amqp</artifactId>
</dependency>application.properties文件中对rabbitmq配置：
spring.application.name=spirng-boot-rabbitmq-sender
spring.rabbitmq.host=(ip)
spring.rabbitmq.port=5672 (这里是5672，在浏览器UI登录时端口为15672)
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest用户名可以是上面新创建用户
采用Direct模式
配置Queue(消息队列)
@Configuration
public class SenderConf {
@Bean
public Queue queue() {
return new Queue(“queue”);
}
}
发送端
@Component
public class HelloSender {
@Autowired
private AmqpTemplate template;
public void send() {
template.convertAndSend("queue","hello,rabbit~");
}
}controller 模拟发送
@Controller
@RequestMapping("/rabbit")
public class HelloController {
@Autowired
private HelloSender helloSender;
@PostMapping("/sender")
public void testRabbit() {
helloSender.send();
}
接受者
@Component
public class HelloReceive {
@RabbitListener(queues="queue") //监听器监听指定的Queue
public void processC(String str) {
System.out.println("Receive:"+str);
}
}
成功接收
