The easiest way to check your CentOS version: log into WebHost Manager (WHM) and check the top of the page.
Terminal users can log into SSH and use multiple commands to retrieve the CentOS version depending on your user privileges:
Regular user:
uname -a
The number after vz indicates CentOS 7 or 6.
Root (administrative) user or user with sudo privileges:
cat /etc/os-release
cat /proc/version
cat /etc/centos-release
sudo hostnamectl
The benefit of seeing multiple options is that one will likely become the most memorable for you at some point.
