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
In vim, you can press “a” to enter text insertion mode, and hit the escape key (Esc) on your keyboard to return to command mode. For a refresher on editing files with vim see: New User Tutorial: Overview of the Vim Text Editor.
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.
