How can I create new users in RHEL 6.8 and assign then sudo access?
There are multiple ways to create sudo users in RHEL. The easiest way is to assign the user to the
The wheel group is a special group which is available by default in most of the Linux distributions. To confirm if wheel group is available in your system, you can use this command.
[root@testvm ~]$ cat /etc/group root:x:0: bin:x:1:bin,daemon daemon:x:2:bin,daemon sys:x:3:bin tty:x:5: disk:x:6: lp:x:7:daemon mem:x:8: kmem:x:9: wheel:x:10: mail:x:12:mail,postfix man:x:15: games:x:20: video:x:39: lock:x:54: ....
The group name
wheel is derived from the phrase
big wheel, which basically means someone with greater power.
In case if you want to see the description of the
[root@testvm ~]$ cat /etc/sudoers .... ## Allows people in group wheel to run all commands %wheel ALL=(ALL) ALL ....
Now create a new user
[root@testvm ~]$ adduser joe
and to get the details of the user
[root@testvm ~]$ id joe uid=502(joe) gid=503(joe) groups=503(joe)
Now to assign the user to the wheel group,
[root@testvm ~]$ usermod -aG wheel joe [root@testvm]$ id joe uid=502(joe) gid=503(joe) groups=503(joe),10(wheel)
Can this user stop/stop processes started by other users in the same wheel group?
