RabbitMQ安装配置以及java的连接配置demo

一、在linux环境下安装

  1、安装Erlang环境（RabbitMQ需要Erlang环境支持）

cd /usr/local/src/ 

mkdir rabbitmq 

cd rabbitmq

wget http://packages.erlang-solutions.com/erlang-solutions-1.0-1.noarch.rpm 

rpm -Uvh erlang-solutions-1.0-1.noarch.rpm

rpm --import http://packages.erlang-solutions.com/rpm/erlang_solutions.asc

sudo yum install erlang

依次输入上述命令，安装Erlang环境

 

2、安装RabbitMq

下载：

 wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.4.1/rabbitmq-server-3.4.1-1.noarch.rpm

 安装：    rpm -ivh rabbitmq-server-3.4.1-1.noarch.rpm

3、RabbitMQ服务的启动

     service rabbitmq-server start

4、设置开机自启动

     chkconfig rabbitmq-server on

5、配置配置文件

       cd /etc/rabbitmq

       cp/usr/share/doc/rabbitmq-server-3.4.1/rabbitmq.config.example /etc/rabbitmq/

       mvrabbitmq.config.example rabbitmq.config

6、开启用户远程访问

vi /etc/rabbitmq/rabbitmq.config

注意要去掉后面的逗号。

7、开启web界面管理工具

rabbitmq-plugins enable rabbitmq_management

service rabbitmq-server restart

8、在防火墙开启端口（15672和5672）

9、在浏览器输入ip:15672就可以访问web管理界面

 

 

备注：默认有guest用户，但是guest用户只能在localhost下能使用，远程访问需新建用户

1、新建用户：rabbitmqctl add_user username password

2、赋予用户角色标签：rabbitmqctl set_user_tags username administrator

然后在浏览器打开web管理界面就可以用该用户名和密码登录，

           登录后点击上方的  admin ，点击下方列表中新建的用户名，在打开的页面中点击    setpermissions  按钮，给角色赋予权限，

           至此，所有的配置结束

 

二、java连接配置demo

1、引入java包依赖

     

<dependency>        <groupId>com.rabbitmq</groupId>        <artifactId>amqp-client</artifactId>        <version>3.0.4</version></dependency><dependency>        <groupId>commons-lang</groupId>        <artifactId>commons-lang</artifactId>        <version>2.6</version></dependency>

编写类文件：

  抽象类EndPoint：

package com.RabbitMQ;import java.io.IOException;import com.rabbitmq.client.Channel;import com.rabbitmq.client.Connection;import com.rabbitmq.client.ConnectionFactory;public abstract class EndPoint{        protected Channel channel;    protected Connection connection;    protected String endPointName;        public EndPoint(String endPointName) throws IOException{        this.endPointName = endPointName;                //创建连接工厂        ConnectionFactory factory = new ConnectionFactory();        //设置host        factory.setHost("192.168.10.43");        factory.setPort(5672);        factory.setUsername("xjiuge");        factory.setPassword("123456");        factory.setVirtualHost("/");        factory.setConnectionTimeout(15000);        //获得连接        connection = factory.newConnection();        //创建通道        channel = connection.createChannel();        //为这个通道申明一个队列，如果这个队列不存在，他将在服务器上创建        channel.queueDeclare(endPointName, false, false, false, null);    }        /**     * 关闭channel和connection     * @throws IOException      */    public void close() throws IOException{        this.channel.close();        this.connection.close();    }}

生产者类：

package com.RabbitMQ;import java.io.IOException;import java.io.Serializable;import org.apache.commons.lang.SerializationUtils;public class Producer extends EndPoint {    public Producer(String endPointName) throws IOException {        super(endPointName);    }    public void sendMessage(Serializable obj) throws IOException{        channel.basicPublish("", endPointName, null, SerializationUtils.serialize(obj));    }}

消费者类：

package com.RabbitMQ;import java.io.IOException;import java.util.HashMap;import java.util.Map;import org.apache.commons.lang.SerializationUtils;import com.rabbitmq.client.AMQP.BasicProperties;import com.rabbitmq.client.Consumer;import com.rabbitmq.client.Envelope;import com.rabbitmq.client.ShutdownSignalException;public class QueneConsemer extends EndPoint implements Runnable, Consumer {    public QueneConsemer(String endPointName) throws IOException {        super(endPointName);    }    public void run() {        try {            //开启接收信息，自动确认            channel.basicConsume(endPointName, true,this);        } catch (Exception e) {            e.printStackTrace();        }    }    /**     * 当用户注册时调用     */    public void handleCancelOk(String consumerTag) {        System.out.println("Consumer "+consumerTag+" registered");    }    /**     * 当有可用新消息时调用     */    public void handleDelivery(String consumerTag, Envelope env,            BasicProperties props, byte[] body) throws IOException {        Map map = (HashMap)SerializationUtils.deserialize(body);        System.out.println("Message Number "+map.get("message number")+"received.");    }    public void handleCancel(String consumerTag){}    public void handleConsumeOk(String consumerTag) {}    public void handleRecoverOk(String consumerTag) {}    public void handleShutdownSignal(String consumerTag, ShutdownSignalException arg1) {}}

测试类：

package com.RabbitMQ;import java.io.IOException;import java.util.HashMap;import java.util.Map;import org.apache.commons.lang.SerializationUtils;import com.rabbitmq.client.AMQP.BasicProperties;import com.rabbitmq.client.Consumer;import com.rabbitmq.client.Envelope;import com.rabbitmq.client.ShutdownSignalException;public class QueneConsemer extends EndPoint implements Runnable, Consumer {    public QueneConsemer(String endPointName) throws IOException {        super(endPointName);    }    public void run() {        try {            //开启接收信息，自动确认            channel.basicConsume(endPointName, true,this);        } catch (Exception e) {            e.printStackTrace();        }    }    /**     * 当用户注册时调用     */    public void handleCancelOk(String consumerTag) {        System.out.println("Consumer "+consumerTag+" registered");    }    /**     * 当有可用新消息时调用     */    public void handleDelivery(String consumerTag, Envelope env,            BasicProperties props, byte[] body) throws IOException {        Map map = (HashMap)SerializationUtils.deserialize(body);        System.out.println("Message Number "+map.get("message number")+"received.");    }    public void handleCancel(String consumerTag){}    public void handleConsumeOk(String consumerTag) {}    public void handleRecoverOk(String consumerTag) {}    public void handleShutdownSignal(String consumerTag, ShutdownSignalException arg1) {}}
