How to Install Cinnamon on CentOS 7

1 - We need to install an group of packages X Server with GUI. As root from terminal, type:

#yum groupinstall "Server with GUI" -y

2 - Install the EPEL repository which contains the RPMs for Cinnamon:

#yum install http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm -y

3 - Install the Cinnamon Packages:

#yum install cinnamon -y

4 - Create a link to tell to the systemd to boot into runlevel 5 (desktop environment). The systemd is a replacement for the Linux init daemon and will start, stop the service etc:

#ln -sf /lib/systemd/system/runlevel5.target /etc/systemd/system/default.target

5 - Reboot and check out the graphic user interface, you may be asked to fill some information:
