Puppeteering with Puppet

So I’ve been a very naughty sysadmin recently, one of the things I intended to do early on in my new employment was setup some form of System Management as we have several Linux hosts. However truth be told I have never had a System Management system for Linux hosts (due to a lack of time to implement one) and due to a number of tight deadlines I’ve had to put this on the back burner and spin up servers for additional roles.

This road however will lead to ruin so I have put a stop to the random spinning up of hosts for anything other than testing until I get something in place to mange all the configurations centrally. The question for me was what to use, I’ve heard of both Puppet and Chef, but I have no experience of them. So after doing a bit of reading I figured I’d go with Puppet as it seems to have most of the bases I am interested in covered.

Deploy Centos 6 from VMWare Template

This is just a quick gotcha that I found ages ago then forgot about and then had to figure out again. Before you convert the VM to a template.

rm /etc/udev/rules.d/70-persistent-net.rules

sed -i ‘/HWADDR*/d’ /etc/sysconfig/network-scripts/ifcfg-eth0

sed -i ‘/UUID*/d’ /etc/sysconfig/network-scripts/ifcfg-eth0

 

Update:

This also applies to SLES 11 SP2 (use /etc/sysconfig/network/ifcfg-eth0)
