How to Add a User and Grant Root Privileges on CentOS 7

Note:

  1. These instructions are intended specifically for adding a user on CentOS 7
  2. User need to be logged in a vps with root user
Step 1: Add the User

It’s just one simple command to add a user. In this case, we’re adding a user called mynewuser :

adduser mynewuser

Now set the password for the new user:

passwd mynewuser
Step 2: Grant Root Privileges to the User

For a refresher on editing files with vim see: Vim Text Editor

visudo
i

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 mynewuser . Add the following below that code:

mynewuser ALL=(ALL) ALL

Then exit by pressing Esc and save the file with the command :wq.

If you’ve followed the instruction above correctly, then you should now have a user setup by the name of mynewuser which can use sudo to run commands as root!
