How To Add User to Sudoers or Sudo Group in CentOS 7

The sudo command stands for “Super User DO” and temporarily elevates the privileges of a regular user for administrative tasks. The sudo command in CentOS provides a workaround by allowing a user to elevate their privileges for a single task temporarily.

This guide will walk you through the steps to add a user to sudoers in CentOS.


  • A system running CentOS 7
  • Access to a user account with root privileges

Step 1. Login to the server with root privileges.

root@'s password:

step 2. Add a user with the following command

root@cloudserver-rootdenied ~]# adduser narender

step 3. Set password of the user with the following command

root@cloudserver-rootdenied ~]# passwd narender

Step 4. Now run the following command

root@cloudserver-rootdenied ~]# visudo

Step 5. Now edit the visudo file and unselect the below line

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

Adding User to the wheel Group

The easiest way to grant sudo privileges to a user on CentOS is to add the user to the “wheel” group. Members of this group are able to run all commands via sudo and are prompted to authenticate themselves with their password when using sudo.

Step 6. To add a user to the wheel group, use the command:

root@cloudserver-rootdenied ~]# useradd -aG wheel narender

Step 7. Switch to the new (or newly-elevated) user account with the su (substitute user) command:

root@cloudserver-rootdenied ~]# su - narender
# sudo ls -la /root

Now user is able to execute commands with sudo privilege
