I've installed CentOS 7 on a Dell PowerEdge R320. I did the minimal install and its starting up at the command line. Is there anyway to switch to the regular gui without reinstalling or a internet connection. I could load a file to a usb stick and go from there... Or would a complete re install be faster?

It looks like you've installed the minimal CentOS install from the smallest ISO they have. In other words, you have the bare minimum you need to have a working system. For Linux gurus, this is called an OS. That being said, you have three options.

  • Option 1: Get the DVD ISO and install it with the GUI.
  • Option 2: Get the netinstall and don't forget to choose the Gnome Desktop Environment from the package list to install the GUI.
  • Option 3: Get internet connection on the system and simply install it using yum.

I would suggest going with option 3 as it is the easiest and possibly as simple as running

dhcpcd ens0p0

I would suggest checking the following link if your network is configured as DHCP.

a complete reinstall can be fast, from dvd onto an SSD I can do it in less than 1 hour: the first 5-10 minutes is booting dvd and getting through the install gui to the final ok click then about 20-30 minutes to install to the disk followed by the reboot and account & network setup and the little things. For the install you would choose server with gui or gnome desktop as opposed to "minimal install".

with a minimal install you are I think at runlevel 3 or now known as multi-user.target. To get to runlevel 5 full graphics you can do either init 5 or systemctl isolate graphical.target. However if you don't have that stuff installed, I don't know what would happen actually.

# this will return the current setting the OS runlevel is set to boot
# automatically.  I suspect a minimal install will put you to runlevel 3 having
# full network capability but no graphics which is systemd multi-user.target

systemctl get-default

# to set the runlevel to boot to full graphics full networking.

systemctl set-default graphical.target

# for an already installed system, have the centos7 install dvd (or usb)
 present as a repository so that you can basically carry on where the minimal
 install stopped.  You don't require networking to do this:

yum grouplist
yum groupinstall "Server with GUI"


# for a minimal install system this should work, but with the stuff you
# take for granted like networking, centos and EPEL repositories being
# available, not having to worry about dependencies and setting up repo's
# then a complete reinstall from dvd may be fast enough and less headache/risk.
