sudo command stands for “Super User DO” and temporarily elevates the privileges of a regular user for administrative tasks.
Step 1: Verify the Wheel Group is Enabled
Your CentOS 7 installation may or may not have the wheel group enabled.
Open the configuration file by entering the command:
Scroll through the configuration file until you see the following entry:
## Allows people in group wheel to run all commands # %wheel ALL=(ALL) ALL
If the second line begins with the # sign, it has been disabled and marked as a comment. Just delete the # sign at the beginning of the second line.

# usermod –aG wheel <username>

su (substitute user) command:
su - <username>
