一 .安装运行ActiveMQ：
1.下载activemq
wget http://archive.apache.org/dist/activemq/apache-activemq/5.9.0/apache-activemq-5.9.0-bin.tar.gz
2.解压
tar -xf apache-activemq-5.9.0-bin.tar.gz
[zcw@g1 ~]$ cd apache-activemq-5.9.0
[zcw@g1 apache-activemq-5.9.0]$ cd bin/
3.运行：
[zcw@g1 bin]$ activemq start
三种运行方式：
(1)普通启动 ./activemq start
(2)启动并指定日志文件 ./activemq start >tmp/smlog
(3)后台启动方式nohup ./activemq start >/tmp/smlog
前两种方式下在命令行窗口关闭时或者ctrl+c时导致进程退出，采用后台启动方式则可以避免这种情况
管理后台为：
http://ip:8161/admin/
4.检查已经启动
ActiveMQ默认采用61616端口提供JMS服务，使用8161端口提供管理控制台服务，执行以下命令以便检验是否已经成功启动ActiveMQ服务。
打开端口：nc -lp 61616 &
查看哪些端口被打开 netstat -anp
查看61616端口是否打开： netstat -an | grep 61616
检查是否已经启动：
(1).查看控制台输出或者日志文件
(2).直接访问activemq的管理页面：http://localhost:8161/admin/
5.关闭
如果开启方式是使用(1)或(2)，则直接ctrl+c或者关闭对应的终端即可
如果开启方式是(3),则稍微麻烦一点：
先查找到activemq对应的进程：
ps -ef | grep activemq
然后把对应的进程杀掉，假设找到的进程编号为 168168
kill 168168
二.创建ActiveMQ的Eclipse项目并运行
1）P2P方式
到中心仓库（
http://search.maven.org/
）里面找到：activemq-core
