activemq无法启动问题

Posted on Edited on In

安装完成后，首先要启用默认实例：

1
# ln -sf /etc/activemq/instances-available/main /etc/activemq/instances-enabled/main

然后以debug方式启动activemq的main实例：

1
# /etc/init.d/activemq console main

会有错误提示：

1
2
ERROR Temporary Store limit is 50000 mb, whilst the temporary data directory: /var/lib/activemq/main/data/localhost/tmp_storage only has 3346 mb of usable space

这是因为硬盘空间不够了，需要更改配置文件/etc/activemq/instances-enabled/main/activemq.xml，broker节内添加以下行：

1

3
4
5
6
7
8

 <systemUsage>
 <systemUsage>
 <storeUsage>
 <storeUsage limit="1 gb"/>
 </storeUsage>
 <tempUsage>
 <tempUsage limit="500 mb"/>
 </tempUsage>
 </systemUsage>
</systemUsage>

如果不配置storeUsage,会有这样的错误提示：

1
ERROR Store limit is 0 mb, whilst the max journal file size for the store is: 32 mb, the store will not accept any data when used.
