12.RabbitMQ多机集群

Posted 2020-10-19 奋斗的一线码农

配置两台Linux CentOS 6.7虚拟主机

CentOS6.7下载地址

安装视频下载

rabbitmq2

rabbitmq1

1、分别在两台主机上修改/etc/hosts

192.168.169.100 rabbitmq1

192.168.169.110 rabbitmq2

 

2、从客户端上传RPM包

RPM包下载地址

3、下载阿里云Yum源

#wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

依次安装Erlang，Rabbitmq

#yum -y install openssl

#yum -y install socat-1.7.2.4-1.el6.rf.x86_64.rpm

#yum -y install erlang-17.4-1.el6.x86_64.rpm

#yum -y install rabbitmq-server-3.6.3-1.noarch.rpm

4、启动rabbitmq1,rabbitmq2上的RabbitMQ

rabbitmq1

#service rabbitmq-server start

rabbitmq2

#service rabbitmq-server start

5、从rabbitmq1主机上拷贝文件到rabbitmq2

scp /var/lib/rabbitmq/.erlang.cookie  rabbitmq2:/var/lib/rabbitmq

6、在rabbitmq1,rabbitmq2上分别关闭防火墙

[[email protected] ~]# service iptables stop

[[email protected] ~]# service iptables stop

7、在rabbitmq1,rabbitmq2上分别启动RibbitMQ

[[email protected] ~]# service rabbitmq-server start

[[email protected] ~]# service rabbitmq-server start

 

8、在rabbitmq2上执行

rabbitmqctl stop_app

rabbitmqctl join_cluster rabbit@rabbitmq1

rabbitmqctl start_app

9、查看各节点上的状态

rabbitmqctl cluster_status

 

10、在rabbitmq1,rabbitmq2节点上分别添加用户和设置控制台插件

 

[[email protected] ~]# rabbitmq-plugins enable rabbitmq_management

 

[[email protected] ~]# rabbitmqctl add_user admin admin

 

[[email protected] ~]# rabbitmqctl set_permissions admin ".*" ".*" ".*"

 

[[email protected] ~]# rabbitmqctl set_user_tags admin administrator

 

[[email protected] ~]# rabbitmq-plugins enable rabbitmq_management

 

 

11、在rabbitmq1节点上安装haproxy

yum -y install haproxy

12、配置haproxy

cp /etc/haproxy/haproxy.cfg  /etc/haproxy/haproxy.cfg.bak

vi /etc/haproxy/haproxy.cfg

添加配置信息

listen rabbitmq_local_cluster 192.168.169.100:5670 

mode tcp 

balance roundrobin 

server rabbit 192.168.169.100:5672 check inter 5000 rise 2 fall 3

server rabbit 192.168.169.110:5672 check inter 5000 rise 2 fall 3 

listen private_monitoring :8100 

mode http 

option httplog 

stats enable 

stats uri /stats 

stats refresh 60s

13、启动haproxy

service haproxy start

14、查看haproxy控制台

http://192.168.169.142:8100/stats

15、建立RabbitMQ策略

16、建立持久队列

 

 

测试代码

Producer.java

package com.test.cluster;

 

import com.rabbitmq.client.*;

 

import java.io.IOException;

import java.lang.String;

import java.lang.System;

import java.util.HashMap;

import java.util.Map;

import java.util.Scanner;

 

public class Producer {

 

    public static void main(String[] args) throws Exception {

   

    //使用默认端口连接MQ

        ConnectionFactory factory = new ConnectionFactory();

    factory.setUsername("admin");

    factory.setPassword("admin");

        factory.setHost("192.168.169.100"); //使用默认端口5672

        factory.setPort(5670);

        Connection conn = factory.newConnection(); //声明一个连接

        Channel channel = conn.createChannel(); //声明消息通道

   

        String exchangeName = "TestEXG";//交换机名称

        String routingKey = "RouteKey1";//RoutingKey关键字

        channel.exchangeDeclare(exchangeName, "direct", true);//定义声明交换机

        String queueName = "ClusterQueue";//队列名称

        Map arg = new HashMap();

        arg.put("x-ha-policy", "all");

        channel.queueDeclare(queueName, false, false, false, arg);

 

        channel.queueBind(queueName, exchangeName, routingKey);//定义声明对象

        

        byte[] messageBodyBytes = "Hello, world!".getBytes();//消息内容

        channel.basicPublish(exchangeName, routingKey, null, messageBodyBytes);//发布消息

        //关闭通道和连接

channel.close();

conn.close();

    }

 

}

 

 

Customer.java

 

package com.test.cluster;

import com.rabbitmq.client.Channel;

import com.rabbitmq.client.Connection;

import com.rabbitmq.client.ConnectionFactory;

import com.rabbitmq.client.QueueingConsumer;

 

import java.io.IOException;

import java.util.HashMap;

import java.util.Map;

 

//通过channel.basicAck向服务器发送回执,删除服务上的消息

public class Consumer {

 

    public static void main(String[] args) throws IOException, InterruptedException {

        ConnectionFactory factory = new ConnectionFactory();

    factory.setUsername("admin");

    factory.setPassword("admin");

        factory.setHost("192.168.169.100"); //使用默认端口5672

        factory.setPort(5670);

        Connection conn = factory.newConnection(); //声明一个连接

        Channel channel = conn.createChannel(); //声明消息通道

        String exchangeName = "TestEXG";//交换机名称

        String queueName = "ClusterQueue";//队列名称

        channel.exchangeDeclare(exchangeName, "direct", true);//定义声明交换机

        channel.queueBind(queueName, exchangeName, "RouteKey1");

 

        channel.basicQos(1); //server push消息时的队列长度

 

        //用来缓存服务器推送过来的消息

        QueueingConsumer consumer = new QueueingConsumer(channel);

 

        channel.basicConsume(queueName, false, consumer);

 

        while (true) {

            QueueingConsumer.Delivery delivery = consumer.nextDelivery();

            System.out.println("Received " + new String(delivery.getBody()));

 

            //回复ack包，如果不回复，消息不会在服务器删除

            channel.basicAck(delivery.getEnvelope().getDeliveryTag(), false);

        }

    }

}

 

关闭掉其中一个RabbitMQ，测试群集效果
