CentOS-7-x86_64-LiveKDE-1804.iso
These images are Live images of CentOS Linux 7. Depending on the name they use the respective display manager. They are designed for testing purposes and exploring the CentOS Linux 7 environment. They will not modify the content of your hard disk, unless you choose to install CentOS Linux 7 from within the Live environment. Please be advised that you can not change the set of installed packages in this case. This needs to be done within the installed system using 'yum'.CentOS-7-x86_64-Minimal-1804.iso
The aim of this image is to install a very basic CentOS Linux 7 system, with the minimum of packages needed to have a functional system. Please burn this image onto a CD and boot your computer off it. A preselected set of packages will be installed on your system. Everything else needs to be installed using yum. The set of packages installed by this image is identical to the one installed when choosing the group named "Minimal" from the full DVD image.Using the installation images
=============================You can burn these images to a DVD or 'dd' them to a USB flash drive.
After the boot media has been prepared, boot the computer off the boot media. If you do an install to your hard disk using these installation images, please remember to run "yum update" after the installation to update your system to the latest packages.Remember that in order to be able to partition your disk you will need to run
the GUI installer which in turns needs enough RAM. The same is true for the
network setup step. Please refer to the release notes available at
http://wiki.centos.org/Manuals/ReleaseNotes/CentOS7 for more details about
these aspects.
