spring boot链接rabbitMQ问题

1、远程链接超时org.springframework.amqp.AmqpConnectException: java.net.ConnectException: Connection timed out: connect

1.在虚拟机上面打开5672和15672端口具体操作如下

CentOS 7.0默认使用的是firewall作为防火墙，这里改为iptables防火墙。

1.1 安装iptables防火墙

yum install iptables-services

1.2 编辑防火墙配置文件

vi /etc/sysconfig/iptables

编辑内容如下：

# sample configuration for iptables service
# you can edit this manually or use system-config-firewall
# please do not ask us to add additional ports/services to this default configuration
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
#-A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT
#这里是你要暴露的端口start
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 5672 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 15672 -j ACCEPT
#这里是你要暴露的端口end
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT

:wq! #保存退出

1.3 最后重启防火墙使配置生效

systemctl restart iptables.service

1.4 设置防火墙开机启动

systemctl enable iptables.service

1.5 使用telnet测试端口是否可以访问（如果telnet命令用不了自己百度跟着教程做就可以了）运行成功的效果就是没有效果

2、问题二：Caused by: com.rabbitmq.client.ShutdownSignalException: connection error; protocol method:

2. 输入你的机器的IP：15672进入rabbitMQ的登陆管理界面

2.1 点击admin，进去点击set permission

2.2 就OK了

代码测试链接

添加依赖

<!--添加消息总线RabbitMQ支持-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-bus-amqp</artifactId>
        </dependency>

测试代码

   private String QUEUE_NAME = "hello";

    @Test
    public void test1() throws Exception{
        ConnectionFactory factory = new ConnectionFactory();
        factory.setHost("192.168.9.167");
        factory.setPort(5672);
        factory.setUsername("admin");
        factory.setPassword("123456");
        Connection connection = factory.newConnection();
        Channel channel = connection.createChannel();

        channel.queueDeclare(QUEUE_NAME, false, false, false, null);
        String message = "Hello World from Windows!";
        channel.basicPublish("", QUEUE_NAME, null, message.getBytes());
        System.out.println(" [x] Sent ‘" + message + "‘");

        channel.close();
        connection.close();
    }

最后注意：远程链接不能用默认的guest账号，需要添加新的管理员，具体教程在我之前的Linux安装rabbitMQ中
