1.在服务器（阿里云ubuntu16.04）上安装activemq，我是直接下载activemq：
wget http://archive.apache.org/dist/activemq/apache-activemq/5.6.0/apache-activemq-5.6.0-bin.tar.gz
2.解压及安装，可以通过activemq --help 查看一些命令及参数信息；
3.启动activemq；
4.编写简单的java demo：

import org.apache.activemq.ActiveMQConnectionFactory; import javax.jms.*;
import java.util.concurrent.atomic.AtomicInteger; /**

//从工厂中创建一个链接

以上仅仅是一个简单的demo，实际生产环境种使用，须要考虑使用场景，配置activemq的配置文件，以及与项目的整合问题。
