===== Allow a User to use sudo =====

You can allow a user to use sudo either by adding them to a group which is allowed to sudo, or by specifying the individual user.

Use visudo to edit /etc/sudoers, it uses the system default editor, which is normally vi or vim if it's installed:

  [root@machine ~]# visudo

==== Using Groups ====

Uncomment the line:

  # %wheel        ALL=(ALL)       ALL

Then add your user to the wheel group:

  [root@machine ~]# adduser adam wheel

==== Individual Users ====

Add a new line which specifies the user:

  adam        ALL=(ALL)       ALL


Now the user adam will be able to use the sudo command.
