Centos 5.4 PXE Boot

Centos 5.4 PXE Boot

Quick Intro Some time ago I setup a PXE boot server at work so we could deploy different operating systems to our servers and computers quickly. I’m lazy like that. We use it to deploy Centos 5.3, Centos 4.4, and a few different versions of the Mirth Appliances. Here’s how I added Centos 5.4 to [...]

Alias your cd commands and save time

Alias your cd commands and save time

When you’re bouncing around from one directory to another in Linux or OSX, or even Cygwin in windows, remember you can use alias to save you time. For example, I’ve been working a lot on these two directories in my pxeboot server ((The xxxx is just a placeholder)). /opt/xxxx/sources/linuxdistros/centos/x86_64/5.3 /opt/xxxx/sources/linuxdistros/centos/x86/4.4 Typing those in each time, [...]

Troubleshooting the kickstart file

My previous post about CentOS 5.3 ended up somewhat incomplete, and I wanted to finish up by showing how I did a little bit of troubleshooting to fix it. I now can install CentOS 5.3 64bit automagically just by selecting the entry from the PXEboot menu; Love it! There were two problems with the kickstart [...]

Oracle VM manager

Virtualization is the next big thing in computing. I’ve been using VMware, Qemu, MS Virtual PC and a couple others for years, so it is obvious that virtualization isn’t new. I regularly work on OpenVZ environments where we run dozens of servers in one physical box, and in some cases we’ve been able to reduce [...]
