activemq linux jms

1.下载activeMQ安装包,拷贝到/activeMQ目录下
apache-activemq-5.10.0-bin.tar.gz，下载地址http://activemq.apache.org/download.html

2.解压文件到运行目录

[root@iZ94wmbxqzyZ softs]# tar -xzvf /server/apache-activemq-5.10.0-bin.tar.gz

3.为了方便管理，重命名

[root@iZ94wmbxqzyZ softs]# mv apache-activemq-5.10.0 activemq-5.10.0

[root@iZ94wmbxqzyZ softs]# cd activemq-5.10.0/
[root@iZ94wmbxqzyZ activemq-5.10.0]# ll

4.启动服务

[root@iZ94wmbxqzyZ bin]# ./activemq start
INFO: Using default configuration
(you can configure options in one of these file: /etc/default/activemq /root/.activemqrc)

INFO: Invoke the following command to create a configuration file
./activemq setup [ /etc/default/activemq | /root/.activemqrc ]

INFO: Using java '/softs/jdk1.6.0_30/bin/java'
INFO: Starting - inspect logfiles specified in logging.properties and log4j.properties to get details
INFO: pidfile created : '/softs/activemq-5.10.0/data/activemq-iZ94wmbxqzyZ.pid' (pid '28962')

5.查看是否启动成功

[root@iZ94wmbxqzyZ bin]# 
[root@iZ94wmbxqzyZ bin]# ps -ef | grep activemq
root     28962     1 32 23:32 pts/0    00:00:04 /softs/jdk1.6.0_30/bin/java -Xms1G -Xmx1G -Djava.util.logging.config.file=logging.properties -Djava.security.auth.login.config=/softs/activemq-5.10.0/conf/login.config -Dcom.sun.management.jmxremote -Djava.awt.headless=true -Djava.io.tmpdir=/softs/activemq-5.10.0/tmp -Dactivemq.classpath=/softs/activemq-5.10.0/conf; -Dactivemq.home=/softs/activemq-5.10.0 -Dactivemq.base=/softs/activemq-5.10.0 -Dactivemq.conf=/softs/activemq-5.10.0/conf -Dactivemq.data=/softs/activemq-5.10.0/data -jar /softs/activemq-5.10.0/bin/activemq.jar start
root     29011 28898  0 23:32 pts/0    00:00:00 grep activemq
[root@iZ94wmbxqzyZ bin]# 
[root@iZ94wmbxqzyZ bin]#

6.停止服务

[root@iZ94wmbxqzyZ data]# 
[root@iZ94wmbxqzyZ data]# kill 28962
[root@iZ94wmbxqzyZ data]# 
[root@iZ94wmbxqzyZ data]# ps -ef | grep activemq
root     29078 28898  0 23:42 pts/0    00:00:00 grep activemq
[root@iZ94wmbxqzyZ data]#

到此环境准备成功
