We all as a Linux administrator must have come across this error sometime in our lives.

[user@host dir]$ sudo bash
sudo: effective uid is not 0, is sudo installed setuid root?

This happens when sudo does not get the right access permissions.

The Solution for this error is giving the following permissions as root user

chmod u+s /usr/bin/sudo

That Must Sort the issue for CentOS Kind of distros.
