1. 场景描述
朋友项目需要弄个测试环境,稍微帮忙了下,系统不复杂,但是需要自己安装mysql、Reids、Es、RabbitMq等,Mq主要用在同步用户信息与发送站内消息和短信上,RabbitMq以前没记录,刚好又重新走了一遍,记录下部署、测试、常见问题,有需要的朋友,拿走不谢!
2.解决方案
2.1 mq部署
安装说明,版本没有用最新的版本,用的2018年的3.6.15,最新的在github上下载太慢了。
2.1.1 安装erlang语言相关包
[root@ruanjianlaowang ~]# yum install epel-release[root@ruanjianlaowang ~]# yum install erlang[root@ruanjianlaowang ~]# wget https://packages.erlang-solutions.com/erlang-solutions-1.0-1.noarch.rpm[root@ruanjianlaowang ~]# rpm -Uvh erlang-solutions-1.0-1.noarch.rpm
2.1.2 安装rabbitmq
[root@ruanjianlaowang ~]# wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.15/rabbitmq-server-3.6.15-1.el7.noarch.rpm[root@ruanjianlaowang ~]# yum install rabbitmq-server-3.6.15-1.el7.noarch.rpm#开启允许远程访问[root@ruanjianlaowang ~]# cat /etc/rabbitmq/rabbitmq.config [{rabbit, [{loopback_users, []}]}].假如文件或者内容不存在,添加下(3.6.6版本没有)[root@ruanjianlaowang ~]# vi /etc/rabbitmq/rabbitmq.config[root@ruanjianlaowang ~]# rabbitmq-plugins enable rabbitmq_management#安装延迟插件,特定场景,非必须[root@ruanjianlaowang ~]# cd /usr/lib/rabbitmq/lib/rabbitmq_server-3.6.15/plugins[root@ruanjianlaowang ~]# wget https://dl.bintray.com/rabbitmq/community-plugins/rabbitmq_delayed_message_exchange-0.0.1.ez[root@ruanjianlaowang ~]# rabbitmq-plugins enable rabbitmq_delayed_message_exchange#防火墙放行端口号[root@ruanjianlaowang ~]# firewall-cmd --add-port=15672/tcp --permanent[root@ruanjianlaowang ~]# firewall-cmd --add-port=5672/tcp --permanent#启动关闭查看等命令[root@ruanjianlaowang ~]# service rabbitmq-server start[root@ruanjianlaowang ~]# service rabbitmq-server status[root@ruanjianlaowang ~]# service rabbitmq-server restart[root@ruanjianlaowang ~]# service rabbitmq-server stop
启动成功图:
2.1.3 控制台新增用户和虚拟机
(1)控制台地址:http://45.122.146.23:15672/#/(阿里云的服务器,ip改成自己安装mq的地址)
(2)两个端口,控制台:15672,消息通讯:5672
(3)添加用户
(4)添加虚拟host
其实类似linux中的文件,默认是/目录下,创建一个虚拟host便于区分。
(5)关联用户和虚拟host
点击用户,会弹出赋权的页面
(6)配置完成
2.2 rabbitmq验证
直接用官方提供的验证代码,更改下配置就可以,两个类一个发送消息,一个接受消息。
2.2.1 官网demo地址:
https://github.com/rabbitmq/rabbitmq-tutorials/blob/master/java/Send.java
2.2.2 测试
(1)idea下测试,springboot项目,两个depency就可以了,pom文件
<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.3.1.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.laowang</groupId> <artifactId>mqtest</artifactId> <version>0.0.1-SNAPSHOT</version> <name>mqtest</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-amqp</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build></project>
效果图如下:
(2)消息推送类:Send.java
package com.laowang.mqtest.hello;import com.rabbitmq.client.Channel;import com.rabbitmq.client.Connection;import com.rabbitmq.client.ConnectionFactory;import java.nio.charset.StandardCharsets;public class Send { private final static String QUEUE_NAME = "hello"; public static void main(String[] argv) throws Exception { ConnectionFactory factory = new ConnectionFactory();// factory.setHost("localhost"); factory.setHost("45.122.146.23"); factory.setPort(5672); factory.setVirtualHost("ruanjianlaowang"); factory.setUsername("ruanjianlaowang"); factory.setPassword("123"); try (Connection connection = factory.newConnection(); Channel channel = connection.createChannel()) { channel.queueDeclare(QUEUE_NAME, false, false, false, null); String message = "Hello World!"; channel.basicPublish("", QUEUE_NAME, null, message.getBytes(StandardCharsets.UTF_8)); System.out.println(" [x] Sent '" + message + "'"); } }}
(3)消息接受类Recv.java:
package com.laowang.mqtest.hello;import com.rabbitmq.client.Channel;import com.rabbitmq.client.Connection;import com.rabbitmq.client.ConnectionFactory;import com.rabbitmq.client.DeliverCallback;public class Recv { private final static String QUEUE_NAME = "hello"; public static void main(String[] argv) throws Exception { ConnectionFactory factory = new ConnectionFactory();// factory.setHost("localhost"); factory.setHost("45.122.146.23"); factory.setPort(5672); factory.setVirtualHost("ruanjianlaowang"); factory.setUsername("ruanjianlaowang"); factory.setPassword("123"); Connection connection = factory.newConnection(); Channel channel = connection.createChannel(); channel.queueDeclare(QUEUE_NAME, false, false, false, null); System.out.println(" [*] Waiting for messages. To exit press CTRL+C"); DeliverCallback deliverCallback = (consumerTag, delivery) -> { String message = new String(delivery.getBody(), "UTF-8"); System.out.println(" [x] Received '" + message + "'"); }; channel.basicConsume(QUEUE_NAME, true, deliverCallback, consumerTag -> { }); }}
说明:连接信息更改为你自己的连接信息。
(4)执行效果图
发送类:
接受类,发送了三次。
2.3 问题总结:
(1) 虚拟host创建可以带“/”,也可以不带,配置的要注意。
(2) 防火墙记得放开端口号。
