CentOS 7 install is only core?


Hey all, I'm trying to install CentOS 7 on my laptop and as far as I can tell the only way to install it is a core install. I thought I had downloaded the wrong DVD so I tried again with another download and again I can only install core. The DVD is over four gigs so I'm thinking it's user error on my part but I can't figure it out. Googling this problem shows it's not a problem because I can't find anything about it. My laptop is a Lenovo G550 64-bit with 250GB hard drive and eight gigs of RAM. So what am I doing wrong?

Thanks,

Joe B

Since you don't say what ISO you downloaded, I have to offer this:
Live media images are also available, both for Gnome and KDE desktop environments. These allow you to test out CentOS by booting from the DVD or USB stick. The third livecd image uses Gnome, and as the livecd name implies, it is small enough to fit on a CD. This image does not contain libreoffice. You can also install CentOS to your hard disk from the live media images[1]

See also http://ftp.osuosl.org/pub/centos/7.0...4/0_README.txt

I'm downloading http://ftp.osuosl.org/pub/centos/7.0...x86_64-DVD.iso now so I can see what's what in a Vbox appliance.

During the install > Installation Summary > Software > "Software Selection" option.
Default is minimal.

You have 2 choices. Re-install from media and change that or...
use yum to install a desktop.

@ habitual, I've seen live CDs that wouldn't upgrade so I "assumed" these were the same. I will check this out.

@ all, I haven't been getting any options for desktop installs (I've been using OpenSuSE and install options abound). And, once the "core" install finishes not all commands are available: no ifconfig, no df, no a bunch of stuff.

Thanks,

Joe B

Those are installed as a group, if you go to the CENTOS subforum you'll see some screenys that'll show you where you went wrong

Code:
su - root
and enter the root password, and use
Code:
ip a
to see ifconfig type output.

Code:
df -h
worked here on the minimal install.

Maybe PICNIC. You should check md5 or shal before doing a new download. Be sure that those number match the posted ones at Centos or OpenSuse.

As to what is going on is a mystery. I guess doing a memtest for a day wouldn't hurt but also it may pass. Using the slowest burn on high quality disc's helps. Be sure memory does report correctly on memtest.

Even if you did some core install you should be able to add to it later from dvd.

GOT IT!!! For some reason it was hanging on to an earlier failed install (I wonder why that one failed) and I didn't have the disk space to do the install (with 250 gigs?). I didn't think to check out the Installation Destination > Partitioning before trying to change the Software Selection to KDE Desktop; LOL I was going in order down the page. AND, for whatever reason, I couldn't get the install source over to Local. Anyway, it's working and I'm now at 45/1237 and the installation is rolling along. Thanks everyone for lending a hand.

Thanks,

Joe B
