CentOS7 adding a normal user to the Sudoers Administrators group

Minimal installation of CentOS 7, there is a lot of work to do, but found that as a normal user, nothing can be done. At least sudo su is not a drop.

Workaround: Switch to the root user into the/etc directory to edit sudoers, add account to sudoers.

Vi/etc/sudoers

Find root all= (all) all
Add user name All= (all) all

VI find command, in command mode:
/pattern<enter>: Look down for the pattern match string example:/all=
Pattern<enter>: Look up the pattern match string example:? All=
After using the Find command, use the following two keys to quickly find:
N: Continue searching in the same direction
N: Search in the opposite direction

Supplementary Knowledge Point two:
Change file read-only, General save Exit Command ": Wq" is not saved, must ": x!"

Finally logout and switch to the normal user, try Sudo!
