Are you ready to empower your Red Hat Enterprise Linux (RHEL) system by creating sudo users with ease? In this comprehensive guide, we’ll walk you through every step, ensuring you gain complete control over your RHEL environment. Buckle up, and let’s dive into the world of Linux empowerment!

Understanding the Importance of Sudo Users

Before we embark on the journey of creating a sudo user, let’s understand why this is crucial for managing an RHEL system effectively.

In a nutshell, a sudo user is a regular user account with superuser privileges. It allows you to execute administrative commands while maintaining accountability and security. Here’s why you need one:

  • Enhanced Security: Sudo users can perform system-altering tasks with precision, reducing the risk of unintentional damage;
  • Accountability: Actions performed by sudo users are logged, allowing you to track system changes;
  • Granular Control: You decide who gets sudo access, granting specific permissions as needed.

Now that you appreciate the importance of sudo users let’s explore the steps to create one.

Step 1: Accessing the Terminal

To create a sudo user, you’ll need to access the terminal on your RHEL system. Open the terminal by pressing Ctrl+Alt+T or by searching for it in your applications menu.

Step 2: Log in as Root

In the terminal, log in as the root user using the following command:

code

You will be prompted to enter the root password.

Step 3: Adding a New User

Now, let’s add a new user to your RHEL system. Replace <username> with the desired username.

code

Step 4: Setting the Password

Set a secure password for the new user using the following command:

code

Step 5: Granting Sudo Privileges

To grant the newly created user sudo privileges, add them to the wheel group using the following command:

code

Step 6: Configuring sudoers File

Edit the sudoers file using the visudo command:

code

Find the following line:

code

Uncomment the line by removing the # at the beginning. Save and exit the file.

Step 7: Testing sudo Access

To ensure that your new sudo user has the necessary privileges, log out from the root user:

code

Then, log in as the new user:

code

Try running a command that requires sudo privileges, such as

If prompted, enter the user’s password, not the root password.

Step 8: Verifying Sudo Access

Verify that your new user has successfully gained sudo access by running

This command will list the user’s sudo privileges.

Conclusion

Congratulations! You’ve successfully created a sudo user on your RHEL operating system. This is a pivotal step in taking control of your Linux environment while maintaining security and accountability.

Now, you’re equipped to manage your system efficiently, granting or revoking privileges as needed. Empower your RHEL system and elevate your Linux skills with this newfound knowledge.
