Subject Gentoo Init Scripts
Date Thu, 15 Jan 2009 18:10:32 GMT
I have not found information on the net for how to make ActiveMQ work as 
a daemon managed by the startup/init system for Gentoo, so I have had to 
create my own.  Hopefully posting this information to this DL will 
enable others to find this information.  I will also try to get this 
information posted elsewhere on the net, but feel free to 
use/post/re-use this information as you see fit.


In order to get ActiveMQ to run as a daemon and be managed by the init 
system on Gentoo, you will need to create two files.  The first is the 
/etc/init.d/activemq which is the startup script as you would expect.  
The second is the /etc/conf.d/activemq configuration file, which (in 
case you are not familiar with Gentoo's startup system) is sourced by 
the init system when starting a script.  Essentially, when Gentoo gets a 
request to start an init script, it checks in the /etc/conf.d directory 
for a file with the same name as the init script and if found, "sources" 
that file.  As a result, the "Gentoo way" is to place most, if not all 
configuration into these "conf" files in the conf.d directory.

This script is relatively simple and meets my needs, enabling starting, 
stopping, and restarting (automagically handled by the init system, 
which recognizes that if you have a "start" and a "stop" that it can 
chain them together to get a restart).  The system also seems to do a 
good job of managing the "pid" files and knowing when it has and has not 
been started.  The commands and java config were taken from the 
activemq-admin script that is supplied with activemq.  I have not tested 
the debug configuration and could probably be a little more cleaver than 
requiring one to uncomment/comment out the configuration, but perhaps 
someone will take this simple start and build upon it?

If you have any questions or comments on these, please feel free to 
respond back to the DL; however, please also copy me directly if you 
would like me to respond.  Enjoy!

I left the Gentoo copyright statements (GNU flavor) as this was 
essentially re-used from their framework.  I also borrowed heavily from 
the Gentoo startup scripts provided with the Tomcat project which 
demonstrated how to get the init system start and properly recognize 
java.  As a result I take little credit for this work instead owing to 
the maintainers of the Gentoo Tomcat package for their ingenuity and 
hard work.
