Centos – Setting up Sudo in CentOS-7

centossshsudo

In CentOS 6.5, i would do the following to setup sudo for users –

  1. useradd -G wheel -c "John Smith" jsmith
  2. visudo
  3. uncomment this line – %wheel ALL=(ALL) ALL
  4. usermod -G wheel -a jsmith
  5. restart sshd – /etc/init.d/sshd restart
  6. ssh login as jsmith and type 'sudo bash'

When i try the same thing in CentOS 7, i see the following in /var/log/secure – 

Oct  8 05:20:00 localhost sudo: jsmith : user NOT in sudoers ; TTY=pts/1 ; PWD=/home/jsmith ; USER=root ; COMMAND=/bin/bash

Is this procedure not valid for CentOS-7 anymore?

More info –

file /etc/group has this – 

wheel:x:10:randomperson,cartman,jsmith

visudo shows this – 

## Allow root to run any commands anywhere
root    ALL=(ALL)       ALL

## Allows members of the 'sys' group to run networking, software,
## service management apps and more.
# %sys ALL = NETWORKING, SOFTWARE, SERVICES, STORAGE, DELEGATING, PROCESSES, LOCATE, DRIVERS

## Allows people in group wheel to run all commands
wheel   ALL=(ALL)       ALL

## Same thing without a password
# %wheel        ALL=(ALL)       NOPASSWD: ALL

output of sudo -l command – 

[jsmith@localhost ~]$ sudo -l
[sudo] password for jsmith:
Sorry, user jsmith may not run sudo on localhost.
[jsmith@localhost ~]$

You are missing a '%' in the example posted.

It's supposed to be

%wheel   ALL=(ALL)       ALL

not

wheel   ALL=(ALL)       ALL
