Install Installing Cinnamon Desktop Environment On Centos 7

I have recently installed CentOS 7(Minimal Install without GUI) and now I want to install a GUI environment in it.You know what? It turns out Cinnamon is pretty damned great.It's not earth-shattering. There weren't any features that blew me away. The user experience of Cinnamon is extremely familiar – panel on the bottom that contains, from left to right: a launcher, some common app shortcuts, and a window list followed by volume control, time, status and the like. In other words, this is the exact same layout as 99% of all desktop environments on the planet.

Install Cinnamon Desktop Environment on here.
First Add the EPEL Repository (EPEL Repository which is provided from Fedora project.)
Extra Packages for Enterprise Linux (EPEL)

• How to add EPEL Repository?

# yum -y install epel-release
# sed -i -e "s/\]$/\]\npriority=5/g" /etc/yum.repos.d/epel.repo # set [priority=5]
# sed -i -e "s/enabled=1/enabled=0/g" /etc/yum.repos.d/epel.repo # for another way, 
# yum --enablerepo=epel install [Package] # if [enabled=0], input a command to use the repository

• And now install the Cinnamon Desktop Environment from EPEL Repository:
  

  # yum --enablerepo=epel -y install cinnamon* 

• Input a command like below after finishing installation:
  

  # echo "exec /usr/bin/cinnamon-session" >> ~/.xinitrc

  # startx

  • Select System language first.
  • Select your keyboard type.
