How To Install sudo on CentOS 8
sudo is Allows restricted root access for specified users
Introduction
In this tutorial we learn how to install sudo on CentOS 8.
What is sudo
Sudo (superuser do) allows a system administrator to give certain users (or groups of users) the ability to run some (or all) commands as root while logging all commands and arguments. Sudo operates on a per-command basis. It is not a replacement for the shell. Features include per-host basis, copious logging of each command (providing a clear audit trail of who did what), a configurable timeout of the sudo command, and the ability to use the same configuration file (sudoers) on many different machines.
We can use yum or dnf to install sudo on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install sudo.
Install sudo on CentOS 8 Using dnf
Update yum database with dnf using the following command.
sudo dnf makecache --refresh
