Install TeamViewer on Centos7

1. Get the RPM Package

    wget https://download.teamviewer.com/download/linux/teamviewer-host.x86_64.rpm

2.  Install EPEL Repository

    sudo yum -y install epel-release

3. Install TeamViewer

    sudo yum -y install ./teamviewer-host*.rpm

That's all folks!  3 steps only.

Fyi, I referred to https://community.teamviewer.com/t5/Knowledge-Base/How-to-install-TeamViewer-on-Red-Hat-and-CentOS/ta-p/30708 for this.
