How To Create a New Sudo-enabled User on Ubuntu

When managing a server, you’ll sometimes want to allow users to execute commands as “root,” the administrator-level user. The sudo command provides system administrators with a way to grant administrator privileges — ordinarily only available to the root user — to normal users.

In this Demo, you’ll learn how to create a new user with sudo access on Ubuntu 20.04 without having to modify your server’s /etc/sudoers file.

Step 1: Login to your server — SSH into your server as the root user:

ssh root@your_server_ip_address

Step 2: Add a New User to the System - Use the adduser command to add a new user to your system:

adduser megha

It’ll show you the below output.

adding user ‘megha' ...
adding new group “megha' (1001) ...
adding new user ~megha' (1001) with group “megha' ...
Creating home directory ~/home/megha' ...
copying files from ~/etc/skel' ...
New password:
Retype new password:
passwd: password updated successfully
Enter the new value, or press ENTER for the default
Full Name []: Megha
Room Number []:
Work Phone []:
Taoyuan led
Other []:
Is the information correct? [Y/n] Y

Step 3: Add the User to the sudo Group — Use the usermod command to add the user to the sudo group.

usermod -aG sudo megha

Step 4: Test sudo Access — To test that the new sudo permissions are working, first use the su command to switch to the new user account.

su - megha

As the new user, verify that you can use sudo by prepending sudo to the command that you want to run with superuser privileges

sudo command_to_run

For example, you can list the contents of the /root directory, which is normally only accessible to the root user

sudo ls -la /root

The first time you use sudo in a session, you will be prompted for the password of that user’s account. Enter the password to proceed:

Output:
[sudo] password for megha:

Note: This is not asking for the root password! Enter the password of the sudo-enabled user you just created.

If your user is in the proper group and you entered the password correctly, the command that you issued with sudo will run with root privileges.

Woohoo! we created a new user account and added it to the sudo group to enable sudo access.
