7 Issues (and fixes) for installing Puppetlabs Razor on CentOS 6

I’m very fortunate to have a nice lab at work where I have a UCS chassis, fabrics, a few blades and a VNX to play with. Recently I’ve been working on getting our Razor implementation hammered out so messing around with all the good automation bits.

Now, because its a lab, it doesn’t tend to fall into the same patching cycles as our production servers do. My Razor server in particular is an example of this only getting updated when I have the chance to turn a wrench.

So, dusting off the old project, I dusted off yum and did my usual update of puppet, razor and the various bits involved. Now because various things have changed in the 6 months that I’ve had this installed, I had a variety of issues getting everything up to date.

Issue #1 – undefined method `exists?’

Kicking off the puppet agent -t to make sure everything was still working right I was greeted with the following error:

Jul 30 10:34:05 razor puppet-master[5650]: Could not create resources for managing Puppet's files and directories in sections [:main, :master, :ssl, :metrics]: undefined method `exists?' for #<Puppet::Type::Group:0x7ff03987f790>

Google to the rescue!!!

A quick google search and I found this bug, which basically states, update your gems dumbass.

Issue #2 – Out of date Razor

Razor has been pretty fast moving and one of the issues that I had had in my first go around was the the update would recognize the blade, start the install but hang on tools.00. The issue has been documented here.

Ok, no worries, this is a lab right. let’s blow everything away and start fresh with a new install of razor. Unforunately, there are several items that have been fixed within the git repository for razor that have yet to make it into the puppet forge. Seeing as I was attempting to be a lazy bastard and installed from the forge, I welcome you to issues 3, 4, and 5.

Issue #3 – Razor::Nodejs fails to execute ‘/usr/bin/npm install –global express’

Oh goody, nodejs install issues. Nodejs is pretty important for what we’re doing here. I, like many, have found that running the EPEL repositories on my CentOS boxes are a good thing to have in place. It apparently causes some butt hurt in this instance but luckily the change is pretty minor.

When I installed razor, it by default installed several other dependencies. The one we want in this instance is the nodejs module and editing the /etc/puppet/modules/nodejs/manifests/params.pp file fixes the glitch.

Change this:

    'RedHat', 'CentOS', 'OEL', 'OracleLinux': {
      $majdistrelease = $::lsbmajdistrelease ? {
        ''      => regsubst($::operatingsystemrelease,'^(\d+)\.(\d+)','\1'),
        default => $::lsbmajdistrelease,
      }
      $node_pkg = 'node-compat-symlinks'
      $npm_pkg  = 'npm'
      $baseurl  = 'http://patches.fedorapeople.org/oldnode/stable/el$releasever/$basearch/'
      $gpgcheck = $majdistrelease ? {
        '5'     => 0,
        default => 1,
      }
    }

To this:

    'RedHat', 'CentOS', 'OEL', 'OracleLinux': {
      $majdistrelease = $::lsbmajdistrelease ? {
        ''      => regsubst($::operatingsystemrelease,'^(\d+)\.(\d+)','\1'),
        default => $::lsbmajdistrelease,
      }
      $node_pkg = 'nodejs'
      $npm_pkg  = 'npm'
      $baseurl  = 'http://patches.fedorapeople.org/oldnode/stable/el$releasever/$basearch/'
      $gpgcheck = $majdistrelease ? {
        '5'     => 0,
        default => 1,
      }
    }

This change is outlined here.

Issue #4 – Unable to download latest razor microkernel.iso

Error: Could not start Service[razor]: Execution of '/opt/razor/bin/razor_daemon.rb start' returned 1:
Error: /Stage[main]/Razor/Service[razor]/ensure: change from stopped to running failed: Could not start Service[razor]: Execution of '/opt/razor/bin/razor_daemon.rb start' returned 1:

Warning: /Stage[main]/Razor/Rz_image[razor-microkernel-latest.iso]: Skipping because of failed dependencies

The fix is apparently we’re missing a gem that needs to be installed.

# gem install net-scp

After that, smooth sailing.

The fix is to change this:

{
        port            = <%= port %>
        disable         = <%= disable %>

Issue #6 – Warning messages in the Mongo.conf

Very similiar to the xinetd issues. This time in Mongo.

Issue #7 – Missing nodejs when starting razor

# /opt/razor/bin/razor_daemon.rb start
which: no nodejs in (/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/usr/lib)

Really? REALLY!!!

Ok, its installed. But its specifically looking for nodejs inestead of node. This fix seemed to do the trick.

# which node
/usr/bin/node

# cd /usr/bin

# ln -s node nodejs

# which nodejs
/usr/bin/nodejs

Conclusion

Razor is a fast moving project and with it comes all the various bugs for the various flavors of linux. The original code base was written for Ubuntu I believe but other flavors have quickly been picked up. Now they have issues because of the growth issues. But, I’m willing to bet a beer on the fact that all the issues appear to be fixed in the git repository, they just haven’t made it into the forge yet.

The issues are fairly easy to fix if you google and dig a little. Hopefully this post will make it easier for people in the future to find the issues.

Happy Automation Folks!
