SharedFile System Master Slave(共享文件系统)做ActiveMQ集群
WINDOWS环境下:http://www.apache.org/dyn/closer.cgi?path=/activemq/apache-activemq/5.9.0/apache-activemq-5.9.0-bin.zip下载apache-activemq-5.9.0-bin.tar,解压两次,分别命名为activemq1、activemq2,修改activemq1/conf/activemq.xml中<persistenceAdapter>标签下的<kahaDB>文件路径<directory>,修改为E:/activemq_data,详情如下:
