ActiveMQ not running
今天,在虚拟机的Linux系统安装ActiveMQ,发现启动不了,查看状态发现是ActiveMQ not running。
[root@localhost bin]# ./activemq start
INFO: Loading '/root/Desktop/apache-activemq-5.15.8//bin/env'
INFO: Using java '/usr/local/src/java/jdk1.7.0_71/bin/java'

ActiveMQ not running
[root@localhost bin]#
然后在activemq目录下运行 ./bin/activemq console 会以调试模式启动,并将日志输出到当前页面。
[root@localhost apache-activemq-5.15.8]# ./bin/activemq console

发现这个Unsupported major.minor version 52.0错误,到网上查了一下发现是版本问题,我下了最新版的apache-activemq-5.15.8,而我虚拟机装的jdk版本是1.7;所以再去下载activemq的旧版本装就好了。我下载apache-activemq-5.12.0版本再次安装,安装好之后发现可以启动成功,ActiveMQ is running。
