Building Cassandra-Cacti-M6 on Centos 5.5

 

Turns out this is hard to do.    I’m writing this here for my benefit, and everyone else’s, too.  I’ve got a client using Cassandra, and of course you monitor that stuff.  So I figure that using the cassandra-cacti-m6 stuff is a good plan.  That’s cool, it works with Cacti.  Cacti’s pretty snazzy.   My customer is using Centos 5.5 on the monitoring box.  Turns out there are a lot of hoops to jump through for that to work.  So here’s what I did.

  1. Install jpackage-utils
  2. Install the jpackage.repo into /etc/yum.repos.d, and enable the rhel5 targets
  3. Install JDK6 Update 3 (because of the following step)
  4. Install java-1.6.0-sun-compat from ftp://jpackage.hmdc.harvard.edu/JPackage/5.0/generic/RPMS.non-free/

Then I go to install ANT, but I discover something — trying to install ant.noarch complains about “Missing Dependency: /usr/bin/rebuild-security-providers is needed by package”.  This sucks.  So I do some googling, and figure out that someone solved this issue on Centos 5.x.  I do what they did (documented at http://plone.lucidsolutions.co.nz/linux/centos/jpackage-jpackage-utils-compatibility-for-centos-5.x ).  This works great.  The package is built, I install it out of the local build dir.

Then I install ant.noarch and ant-nodeps.noarch.  These do the trick.

The I build cassandra-cacti-m6 as documented in its source tree.  Woo.

It took me a while to dig up and get all this working, but for you, I hope it’s fast and easy.  Enjoy!

Note that on servers with small heaps, this can OOM cassandra pretty easily. Once we get this running against a larger heap, we'll benchmark exactly how much that is, but do be careful on smaller installs.
