However, if you’re granting sudo privileges to multiple users and would like to limit the commands they can run as sudo, you’ll want to keep track of their permissions by making use of the sudoers file. The sudo user we have just created can run commands in the same way the root user can. The sudoers file is a file that exists by default in UNIX/Linux systems and is used to assign elevated privileges to users. When prompted, type Y and hit ENTER to continue with the installation.

The command switches to the sudo user’s home directory. Next, we are going to test its ability to execute privileged commands.įirst, switch to the sudo user as follows: So far, we have created a regular user and added it to the sudo group, effectively granting it elevated privileges to run administrative tasks. This time around, you will notice the user now belongs to two groups: the primary group and sudo. Next, verify that the user now belongs to the sudo groups by running the id and groups command as shown. To add the user to the sudo group, use the usermod command as follows: You can confirm this by running the following command: Step 3: Add the new user to the sudo groupĪt this point, the user belongs only to the primary group.

To get started, log into your Ubuntu 22.04 server instance as the root user with the following SSH command: Now that you know why a sudo user is essential on a Linux system, let’s create and configure a sudo user on Ubuntu 22.04. They should only be granted the minimum rights or permissions needed to perform their role. This is known as the least privilege principle, which is particularly important if you are granting sudo privileges to multiple users. Ideally, a sudo user is granted just enough privileges to allow them to perform the tasks at hand. Sudo stands for either “super user do” or “substitute user do.” A sudo user is a regular user that can run some commands as a root user or with root privileges. In Linux, sudo is a program that allows a regular user to run commands with root privileges or permissions. As such, it’s always recommended to administer the Linux system as a sudo user. All it takes is one bad command to be executed and the whole system can be compromised. The fact that the root user can run any command on the system can also be risky. However, logging in and carrying out commands as root is highly discouraged. The user has rights to execute virtually any command without restriction, including installing and uninstalling applications, modifying configuration files, adding and removing user accounts, upgrading the system, and creating and removing files, among other things. The root user, also known as the superuser, is the user with the highest privileges in a Linux system. To help you accomplish this, the following tutorial will examine how to create a sudo user as well as manage sudo access on Ubuntu 22.04. As a systems administrator, you may want to assign limited admin privileges to a delegated administrator so they can assist with administrative tasks.
