Yes, I have had success starting Cassandra using the CassandraDeamon class and Procrun, but stopping it was slightly problematic. I ran into several problems:
1. I could not get Procrun to start Cassandra (via CassandraDeamon class) when using "JVM" mode. You have to use "JAVA" mode in that case. One of the downside of using "JAVA" mode is that the Cassandra process will show up as "java.exe" instead of something like "Cassandra.exe". Not a big deal, but annoying! 2. When running in "JAVA" mode with Procrun, attempting to stop the service would cause the process to crash instead of cleanly exiting. Even though Cassandra always restarted okay and this may never have caused a problem, for me this was simply not acceptable. Since I wanted to use JVM mode and didn't want Cassandra to crash when attempting to stop it, a simple wrapper class around the CassandraDeamon class made everything work nicely.

I have not been too sophisticated in my configurations, but have been running some simple two node clusters. At this point nothing has "yet" caused me any concern. I have been working on a contrib. package for Cassandra and hope to have something submitted for review in the next week or so. It will include everything needed to run Cassandra as a service. In order to make Cassandra work well with Apache's Procrun<http://commons.apache.org/daemon/procrun.html>, I needed to write a simple WindowsService class. In addition to the procrun executables for 32/64 bit platforms and a batch file to install and remove the service, I'll also be including an ant build file and associated unit tests.

Thank you, Viktor From: Kochheiser,Todd W - TO-DITT1 [mailto:twkochhei...@bpa.gov] Sent: Thursday, June 10, 2010 8:34 PM To: 'user@cassandra.apache.org' Subject: Running Cassandra as a Windows Service For various reasons I am required to deploy systems on Windows. As such, I went looking for information on running Cassandra as a Windows service. I've read some of the user threads regarding running Cassandra as a Windows service, such as this one: http://www.mail-archive.com/user@cassandra.apache.org/msg01656.html I also found the following JIRA issue: https://issues.apache.org/jira/browse/CASSANDRA-292 As it didn't look like anyone has contributed a formal solution and having some experience using Apache's Procrun (http://commons.apache.org/daemon/procrun.html), I decided to go ahead and write a batch script and a simple "WindowsService" class to accomplish the task. The WindowsService class only makes calls to public methods in CassandraDeamon and is fairly simple. In combination with the batch script, it is very easy to install and remove the service. At this point, I've installed Cassandra as a Windows service on XP (32 bit), Windows 7 (64 bit) and Windows Server 2008 R1/R2 (64 bit). It should work fine on other version of Windows (2K, 2K3). Questions: 1. Has anyone else already done this work? 2. If not, I wouldn't mind sharing the code/script or contributing it back to the project. Is there any interest in this from the Cassandra dev team or the user community? Ideally the WindowsService could be included in the distributed source/binary distributions (perhaps in a contrib area) as well as the batch script and associated procrun executables. Or, perhaps it could be posted to a Cassandra community site (is there one?). Todd
