How to Create a Sudo User on Ubuntu
Sudo is a program that runs on Unix-like computer operating systems that enables users to execute programs under the privileges provided by another user, usually the superuser. Sudo refers to either “substitute user do” or “super user do” either of which allows you to temporarily elevate your user account to have root privileges. This is not the same as “su”, which has a more permanent effect.
Our goal here is to walk you through setting up a sudo user on Debian,
Step 1: Configure VPSie cloud server
- Sign in to your system or register a newly created one by logging in to your VPSie account.
- Connect by SSH using the credentials we emailed you.
- Once you have logged into your Ubuntu instances and update your system.
Run the command to upgrade your system,
# apt-get update && apt-get upgrade -y
Step 2: Install sudo
Installing Debian Without sudo is possible. In that case, add sudo via apt-get,
# apt install sudo
Step 3: Register for a user account
Use the adduser command to create a new user account. The user information can be filled in or left blank by pressing ENTER. A user named “testuser” will be created here.
# adduser testuser
Adding user `testuser' ... Adding new group `testuser' (1000) ... Adding new user `testuser' (1000) with group `testuser' ... Creating home directory `/home/testuser' ... Copying files from `/etc/skel' ... New password: Retype new password: passwd: password updated successfully Changing the user information for testuser Enter the new value, or press ENTER for the default Full Name : Room Number : Work Phone : Home Phone : Other : Is the information correct? [Y/n] y
Step 4: Add the new user to the sudo group
Run the following command to add the user you created to the sudo group,
# usermod -aG sudo testuser
Step 5: Test the sudo
To access the newly created user, type the following command,
# su - testuser
# su - testuser To run a command as administrator (user "root"), use "sudo <command>". See "man sudo_root" for details. [email protected]:~$
