Enable root user2015/04/24
The root user in Ubuntu is disabled by default because his password is not set. But if you'd like to use root user by some reason, enable it like follows.
|||Set root password.|
Enter new UNIX password:
# set root password
Retype new UNIX password:
passwd: password updated successfully
# root password
# just switched
The examples on this site show as a root user from now. If you use sudo, add "sudo" at the head of commands.
|||If you enable root, limit users to switch to root.|
# line 15: uncomment and add a group that can switch to root
