I. How to Add a User and Grant Root Privileges on CentOS 7
II. How to Remove (Delete) a User on CentOS 7
- These instructions are intended specifically for removing a user on CentOS 7.
- I’ll be working from a Liquid Web Core Managed CentOS 7 server, and I’ll be logged in as root.
Step 1: Delete the User
It’s just one simple command to delete a user. In this case, we’re removing a user called mynewuser:
userdel mynewuser
If you want to remove all the files for the user, then use -r:
userdel -r mynewuser
Step 2: Remove Root Privileges to the User
For a refresher on editing files with vim see: New User Tutorial: Overview of the Vim Text Editor
visudo
Find the following code:
## Allow root to run any commands anywhere
root ALL=(ALL) ALL
mynewuser ALL=(ALL) ALL
In this case, we’re removing root privileges from the user mynewuser . Remove the following:
mynewuser ALL=(ALL) ALL
Then exit vim by saving the file with the command with :wq .
