Setup Disk array

The SAS hard drives are not recognized when the computer is first taken out of the box

You need to enter the Configuration Menu from the BIOS by hitting Ctrl-S. You get to this point during the boot process by hitting any key after the computer has done a self diagnostic.

The Startup Splash screen takes a while to come up and looks like this

After the above is setup, the standard installation procedure from a Live DVD can be used to install CentOS 7

Window manager

Install FVWM

KDE was very slow so I installed FVWM using

as root

yum install fvwm

I then set the runlevel to 3

systemctl set-default multi-user.target

you then login as daq and create the file ".xinitrc" with the line entry

exec /usr/local/bin/fvwm

this will launch fvwm for you if you type the folowing on the command line

ssh-agent startx

Install Xfce

did not use Xfce as a window manager but used fvwm above

yum install epel-release
yum --enablerep=epel -y groups install "Xfce"

then setup the graphical target

systemctl isolate graphical.target

to keep it as the default

sudo systemctl set-default graphical.target
rm '/etc/systemd/system/default.target'
ln -s '/usr/lib/systemd/system/graphical.target' '/etc/systemd/system/default.target

the command below will check which GUI is used

ls -l /etc/systemd/system/display-manager.service
