解决方案：
首先开启web管理 rabbitmq-plugins enable rabbitmq_management 使用http://localhost:15672浏览器访问。
第一步：find / -name "rabbitmq.config*" –>找到到rabbitmq.config.example文件
打开这个文件：vi /usr/share/doc/rabbitmq-server-3.7.4/rabbitmq.config.example
第二步：修改这个文件如下图

退出 并保存：wq
第三部：将该文件移动到etc/rabbitmq文件夹下并重命名为rabbitmq.config
第四步：重启rabbitmq服务service rabbitmq-server restart
需要注意的是

开启web管理使用的是HTTP协议而java远程访问rabbitmq服务使用的是AMQP协议！

附带java连接工具类代码

public class ConnectionUtil {
	
	public static Connection getConnection () throws Exception{
		ConnectionFactory factory = new ConnectionFactory();
		factory.setHost("192.168.43.93");//虚拟机的localhost
		factory.setPort(5672);
		factory.setUsername("hanyuanLiu");
		factory.setPassword("hanyuanLiu");
		factory.setVirtualHost("/testme");//设置虚拟主机类似于数据库实例
		return factory.newConnection();
	}
}

至此问题解决
