Managing solr machines (start/stop/status)

[Jamie Johnson <je...@gmail.com>]

I know this isn't a solr specific question but I was wondering what
folks do in regards to managing the machines in their solr cluster?
Are there any recommendations for how to start/stop/manage these
machines?  Any suggestions would be appreciated.

What do you mean by manage?

For stopping and starting, I built my own redhat-friendly init script to 
handle jetty.  It uses a file in /etc/sysconfig for commandline options.

You can see my init script here:

Here's what I have in /etc/sysconfig/solr:
STARTARGS="-Xms3072M -Xmx3072M -XX:NewSize=2048M -XX:+UseParNewGC 
-XX:+UseConcMarkSweepGC -XX:+CMSParallelRemarkEnabled 
-Dsolr.solr.home=/index/solr -Dsolr.clustering.enabled=true 
-DSTOP.PORT=8079 -DSTOP.KEY=somePassword"
STOPARGS="-DSTOP.PORT=8079 -DSTOP.KEY=somePassword"

I'm running CentOS5, but I ran into a problem with the fuser command 
that I use in the init script.  I filed a bug with CentOS, but since the 
bug comes from upstream, they were not able to fix it.  You may need to 
install a new psmisc package to use the init script:

The script works fine on CentOS 6.

Thanks,
Shawn

One thing I use is csshx (http://code.google.com/p/csshx/) on my Mac when dealing with the various boxes in our cluster.  You can issue commands in one terminal and they are duplicated in all other windows.  Very useful for global stop/starts and updates.
