Docker : Adding Non Root Users To The Docker Group In Ubuntu

One of the most common task you have to do as a Linux administrator is to add a new user.  Especially developers who always wants root access.

Linux: Switching To root User With The sudo Command On Ubuntu Server

Since Ubuntu does not configure the root account by default you have to manually assign root a password before you can use the root account.  However, there's a way to log in as "root" without setting up the "root" password.  The way to do this is to use the "sudo" and "su" command in combination.  The "sudo" elevates your privileges to root like priviledges, while the "su" command is used to switch from one user to another.  So when used together you get to log in as "root".

So in your Linux prompt type in the following command

sudo su

Linux: Install A Desktop GUI on Ubuntu Server

The topic of installing a desktop GUI has been debated over the years.  Friendships have been ruined because of it.  I don't know if that's true, but some believe that the server should only have command line.  This blog is not about that debate, I just want to see some freaking graphics on the monitor, and for my mouse to be more than a paper weight.  So there's my opinion on the subject.

Anyways installing a GUI on Ubuntu server is really easy.

Here are the steps:

1. Start up your Ubuntu server VM

Linux: Creating a New Virtual Machine for Ubuntu Server

If you are a developer on a shoestring budget, Linux is the way to go if you want to compete with the big boys.  I have nothing against Microsoft, I actually love it a lot on the job.  But when you want to start a personal project, Linux is the way to go, to get the most bang for the buck.

Ubuntu has always been great at offering enterprise level server products for free.  A lot of what you learn with Ubuntu or any server side Linux distribution you can translate into the Windows environment quite easily.  So it's worth the effort.

But before you can do all that you need the Ubuntu server environment up and running.  Instead of going the dual boot route you can have your Windows OS as your main OS and run Ubuntu on a virtual machine, that's where VirtualBox comes in. So let's begin our journey into the world of enterprise Linux.

1. First thing you need is the latest Ubuntu server distribution, you can get it here http://www.ubuntu.com/download/server
