You've been given root credentials. How do you create a new user and make it a sudoer so you can install and remove OS packages?
You know that it is best to use a non-root user for Linux administration. You have been given a root user. How do you create a non-root user with full sudoer privileges?
This example assumes that the username is "mike." Substitute "mike" with the username of your choice.
1. Run this command:
# useradd mike
Then respond to the following prompts.
2. Run this command:
3. While in this text file (in the vi environment), enter this stanza:
mike ALL=(ALL:ALL) ALL
4. Save the changes to the file above. Test the user by running this command:
sudo -i -u mike
5. To full test it, run this:
sudo apt-get install apache2
Respond "n" to the prompt! This is just to test it.
