How to Add a User and Grant Root Privileges on Ubuntu 12.04
- These instructions are intended specifically for adding a user on Ubuntu 12.04 LTS.
- I’ll be working from a sxi.io Web Core Managed Ubuntu 12.04 LTS server, and I’ll be logged in as root.
It’s just one simple command to add a user. In this case, we’re adding a user called mynewuser :
First, you will be prompted to enter the user’s password (twice); do this step. Next, you’ll be prompted to enter in the user’s information. This step is not required, and pressing enter fills the field with the default information:
Adding user `mynewuser' ...
Adding new group `mynewuser' (1001) ...
Adding new user `mynewuser' (1001) with group `mynewuser' ...
Creating home directory `/home/mynewuser' ...
Copying files from `/etc/skel' ...
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
Changing the user information for mynewuser
Enter the new value, or press ENTER for the default
Full Name : User
Room Number :
Work Phone :
Home Phone :
When prompted with the following question, enter Y then hit enter to continue.
Is the information correct? [Y/n] Y
Find the following code:
# User privilege specification
root ALL=(ALL:ALL) ALL
In this case, we’re granting root privileges to the user mynewuser . Add the following below that code:
mynewuser ALL=(ALL:ALL) ALL
Then exit and save the file with the key commands Ctrl-x, Y, enter.
If you’ve followed the instruction above correctly, then you should now have a user setup by the name of mynewuser which can use sudo to run commands as root!
