JMS之ActiveMQ Linux下安裝與應用實例
1.下載activeMQ安裝包,拷貝到/activeMQ目錄下
apache-activemq-5.10.0-bin.tar.gz，下載地址http://activemq.apache.org/download.html
2.解壓文件到運行目錄
[root@linuxidc softs]# tar -xzvf /server/apache-activemq-5.10.0-bin.tar.gz
3.為了方便管理，重命名
[root@linuxidc softs]# mv apache-activemq-5.10.0 activemq-5.10.0
[root@linuxidc softs]# cd activemq-5.10.0/
[root@linuxidc activemq-5.10.0]# ll

4.啟動服務
[root@linuxidc 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-linuxidc.pid' (pid '28962')
5.查看是否啟動成功
[root@linuxidc bin]#
[root@linuxidc 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@linuxidc bin]#
[root@linuxidc bin]#
6.停止服務
[root@linuxidc data]#
[root@linuxidc data]# kill 28962
[root@linuxidc data]#
[root@linuxidc data]# ps -ef | grep activemq
root 29078 28898 0 23:42 pts/0 00:00:00 grep activemq
[root@linuxidc data]#
到此環境准備成功
