[CENTOS] What to do when is not in the sudoers file.This incident will be reported.

--Environment - CentOS Linux release 7.8.2003 (Core)

Event: I was told something when I created a user and sudo

Even if I entered the password I set, it didn't work ...

$ sudo chmod 700 ~/.ssh/id_rsa

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

    #1) Respect the privacy of others.
    #2) Think before you type.
    #3) With great power comes great responsibility.

[sudo] password for ponsuke:
ponsuke is not in the sudoers file.  This incident will be reported.

Because the user is not in a group that can sudo

In the / etc / sudoers file, groups that can use the sudo command are prepared in advance. For Debian, the sudo group. Wheel group for CentOS. How to add a sudo user --Introduction to Linux --Webkaru

I wasn't in the wheel group


$ cat /etc/group | grep wheel
wheel:x:10:centos

Action: Add user to wheel group

  1. Switch to a user who can run sudo
  2. Add a user to the wheel group with ʻusermod`
  3. Switch users and sudo again
#Add user to wheel group
$ sudo usermod -aG wheel ponsuke

#added
$ cat /etc/group | grep wheel
wheel:x:10:centos,ponsuke

#Switch users
$ sudo su - ponsuke
