Adding New User To sudo Group
CentOS 7 has a user group called the “wheel” group, where the members of this group are automatically granted sudo privileges. We will add a new user to this group to grant
sudo privileges to that user. For this purpose we will do the following tasks.
Verify the ‘wheel’ group is enabled
For the first time, we have to verify if the wheel group is enabled. For this purpose we will submit the following command line:
We will be entering to
/etc/sudoers file, then find and remove the ‘remarks sign’ on the left side.
## Allows people in group wheel to run all commands # %wheel ALL=(ALL) ALL
to be :
%wheel ALL=(ALL) ALL
Add New User to wheel Group
To add a new user to wheel group, we will submit the command line :
$ usermod –aG wheel UserName
Adding New User To Sudoers Configuration File
To ensure, a new user having sudo privilege, we have to add to sudoers configuration file.
$ visudocommand line.
- Add new user to sudoers configuration file
## Allow root to run any commands anywhere root ALL=(ALL) ALL ramansah ALL=(ALL) ALL
On this tutorial, we will add a new user called as ‘ramansah’ to the file.
Testing sudo Privilege
After all are set, then we will test a new user to do the root account can do.
[ramansah@localhost /]$ sudo ls -ltr /root total 8 -rw-------. 1 root root 1758 Jul 28 20:27 anaconda-ks.cfg -rw-r--r--. 1 root root 1786 Jul 28 20:40 initial-setup-ks.cfg
