How to Add or Create a New Superuser on Linux – Guide
To create a new superuser account on Linux, you first need to create a user account and grant it administrator privileges. To do this, use the sudo command. The sudo command can be used to perform various administrative functions on your system even though it has non-root access. To use sudo, you must have a superuser account on your system.
There are several Linux operating systems, known as distros, that offer different ways to add sudo users. To add a sudo user in one of these distros, read on to learn more about how to use Linux commands in different distros.
Add a superuser on Ubuntu and Debian
In Ubuntu and other Debian-based distros, there are two ways to add a sudo user. You can do this through the terminal or take a graphical approach using System Settings.
1. The command line approach
sudo adduser username username is the name of the user you want to add. ..
New user: Username
sudo usermod -G sudoers mynewuser
This will add the sudo user to the group username. ..
Where G refers to the Group function and Append refers to the Append function, the following code would create a new group: G = new Group();
sudo -l If the command listed in the output of sudo -l is correct, then you are good to go. If not, you may need to fix the issue and re-run sudo -l. ..
sudo adduser –name=mynewuser –disabled-password This will add the new user mynewuser to the sudoers file.
sudo adduser sudo username -g sudo adduser sudo username -p
The verification process remains the same as before, but there are some new changes.
2. Using the graphical interface
To add a user to the sudo group, you will first need to create a new user account using the command line. After creating the user, follow the steps provided below to proceed. ..
Creating a new superuser in Arch Linux
To get root access on Arch Linux, you must first become root by using the su command. Once you have become root, you can then use the archlinux-sudo command to create a sudo account.
sudo passwd root
sudo useradd -m -g sudo -H “name=MyUser” This will add a new user called MyUser to the sudoers file.
To create a new password for a user, use the passwd command. ..
To add the username to the sudoers list, use the usermod command. ..
usermod –append –groups wheel username wheel = “users”
sudoers -l This will show you the list of users who have access to the sudo command.
sudoers_base=/etc/sudoers This line sets the sudoers file’s base directory to /etc/sudoers. This is important because the sudoers file is read in order from top to bottom, so if this line is not present, sudo will not be able to start up properly.
The all-wheel drive system on most cars is a great feature, but it can also be a hassle. ..
%wheel_line_1% Remove the # symbol before the % wheel line and save your changes. Press Ctrl + O on your keyboard to save the file. ..
curl -X POST https://api.github.com/users/{user} -H “Content-Type: application/json” -d ‘{“login”: “new_user”, “id”: “1”}’ The user was successfully added. ..
$ bash bash: /bin/bash not found ..
sudo -v
If the output displays a root prompt, the current user has administrative access. ..
Adding a sudo account on CentOS
Adding a sudo account to CentOS is a simple process that is similar to the process specified above for Arch Linux. However, some basic changes must be made in order to add a sudo account.
su - This will create a new user called “root” with the privileges of the current user.
To create a new user, use the following command: sudo useradd -m -g wheel -d /home/username/mynewuser This will add the new user to the sudoers list.
To add a user to the wheel group, use the following command: useradd -G wheel username ..
To set the password for a new user, use the passwd command. ..
sudo -u user sudo -v To verify that you have sudo access, type the following commands one by one: sudo -l sudo -p
When you press Enter after entering the first command, the system will prompt you for the new password. Enter the new password to continue. The output of the above command will display root, which means that the current user has root privileges. ..
How to Add a superuser in Fedora
Fedora provides a variety of options for users, including superuser privileges. You can assign these privileges to a new user in a few easy steps by using the Fedora installer or the superuser tools.
adduser newuser To change the user name of an existing user, use the chuser command as follows: chuser newuser newname ..
Set a password for the new user to protect their account from unauthorized access.
usermod -G wheel group new user
Usermod -aG wheel username -g wheel
To modify user accounts in Fedora, use the usermod command. ..
sudoedit /etc/sudoers Add the following line at the end of the file: %wheel ALL=(ALL) NOPASSWD: ALL This will allow all users in the wheel group to run all commands without having to enter a password. ..
#wheel ALL = (ALL)
Group wheel members can now execute any command ..
This command will list all the items in the current directory.
