Pre-Flight Check

• These instructions are specifically for adding a user on Fedora 23. The process is identical in most other Linux operating systems.
• For this tutorial, we’ll be using a Liquid Web Self Managed Fedora 23 server, logged in as root.

Step #1: Add the User

In this case, we’re adding a user called “newuser”:

adduser newuser

Now set the new user’s password:

passwd newuser

After entering the new password, you will need to enter it a second time to confirm.

Step #2: Give the User Root Privileges

We’ll need to edit the sudoers file to add permissions for the new user. To open the file for editing, enter the following command:

visudo

Find the following code:

## Allow root to run any commands anywhere
root ALL=(ALL) ALL

In this case, we’re granting root privileges to the user “newuser”. Add the following below that code:

newuser ALL=(ALL) ALL

Then type :wq to exit and save the file.

If you’ve followed the instructions correctly, then you now should have a user named newuser who can use sudo to run commands as root!

Should you want to remove (delete) the user, follow the instructions at How To Remove (Delete) a User on Fedora 23.
 

Pre-Flight Check

• These instructions are intended specifically for removing a user on Fedora 23. The process on most other Linux operating systems is identical.
• For this tutorial, we’ll be using a Liquid Web Self Managed Fedora 23 server, logged in as root.

Step #1: Delete the User

In this case, we’re removing the user we added in How To Add a User and Grant Root Privileges on Fedora 23, newuser:

userdel newuser

If you want to remove the user and all of the user’s files as well, you can include the “-r” flag:

userdel -r newuser

Step 2: Remove the User’s Root Privileges

Run the command:

visudo

And find the following code:

## Allow root to run any commands anywhere
root ALL=(ALL) ALL
newuser ALL=(ALL) ALL

In this case, we’re removing root privileges from the user “newuser”, so remove the following line:

newuser ALL=(ALL) ALL
