activeMQ安装使用-蒲公英云

下载地址：

http://mirror.esocc.com/apache/activemq/apache-activemq/5.9.0/apache-activemq-5.9.0-bin.tar.gz

拷贝到安装路径。例如：

/usr/local/activeMQ/

解压

tar -xvf apache-activemq-5.9.0-bin.tar.gz

启动activeMQ服务

cd bin/

根据当前系统环境执行使用相应的文件进行启动服务即可。

例如：当前是Linux X86 64位操作系统

cd linux-x86-64

./activemq start

可选择option

{ console | start | stop | restart | status | dump }

启动完成后，就可以通过activeMQ自带的后台管理了。

接下来我们使用跑一个Active自带的事例

Publisher 实现发布

Listener 订阅
