No Such Comfort

CentOS 6 Minimal

Posted by scottj on September 12, 2014 in Custom Development with No Comments

I’ve come to enjoy using CentOS 6 as installed from the minimal CD.  Once it is installed, all you get is a login prompt and a root user.  I take the following steps to set up a personal account:

useradd administrator
passwd administrator            
usermod -G wheel administrator
# uncomment line allowing wheel to use sudo
vi /etc/pam.d/su
# uncomment line requiring wheel to su to root
vi /etc/aliases
# alter line redirecting root's mail

Then I install a very minimal desktop. These instructions assume you’re root, if not, you’ll need to sudo them.

yum groupinstall "Desktop" "Desktop Platform" "X Window System" "Fonts"
vi /etc/inittab
# boot into runlevel 5 instead of runlevel 3

When you’re done, don’t forget to yum upgrade.
