Adding User to Ubuntu

Adding User to Ubuntu

I need a user that I can use when I do not want to risk doing damage to my Ubuntu installation.

So, I ran

sudo su

then ran

adduser curiouswebster

following these instructions,
https://www.digitalocean.com/community/tutorials/initial-server-setup-with-ubuntu-18-04

is ran
usermod -aG sudo curiouswebster

but doesn't this add root privileges for curiouswebster??

If so, please help me downgrade the permissions.

I was hoping to log in as curiouswebster and install various systems, like Apache, MySQL, PHP and WordPress.

Shouldn't I use root for this?

Also, how do I log in as curiouswebster?

Thanks

Thanks. Based on all your feedback, I will proceed to install and configure my Ubuntu for LAMP, using root privileges. I will not bother with configuring a reduced privileges user (for myself) until I get WordPress up and running.

But, I have one final question on sudo.

you said, using "sudo su" was redundant.

I see that sudo -I makes these permissions easier to NOT switch cart blanch to high privileges. Thanks.

But, when I want to turn root privileges ON for the session, what's the best sudo command?

Thanks

Does the term "user to jail" come from the ides that a user is being checked to see if, with his permissions, he had the permission to do something bad on the system?

A true "Jail" is a very specific construct.

This relates to using chroot, LXD, Docker or several other mechanisms to ensure a specific user or set of users only have access to the Jailed runtime environment. This blocks access to machine level files + facilities, also other container access is blocked.

Best to open another question about Jails, as answers can be long.
