ActiveMQ 是Apache出品，最流行的，能力强劲的开源消息总线。ActiveMQ 是一个完全支持JMS1.1和J2EE 1.4规范的 JMS Provider实现，尽管JMS规范出台已经是很久的事情了，但是JMS在当今的J2EE应用中间仍然扮演着特殊的地位。

2 启动ActiveMQ
/usr/local/activemq/bin/activemq setup /home/web/.activemqrc
/usr/local/activemq/bin/activemq start
检查activemq是否已经启动并查看日志是否正常
ps -ef | grep active
tail -fn 100 /usr/local/activemq/data/activemq.log
/usr/local/activemq/bin/activemq stop
3 Activemq 启动脚本
# su - web
Web> cat activemq_61616_restart.sh
#!/bin/bash
# restart activemq port 61616
cd
/usr/local/activemq1/bin/activemq stop
if [ -f /usr/local/activemq1/data/activemq.pid ]
then
rm -f /usr/local/activemq1/data/activemq.pid
fi
sleep 5
