Install Ubuntu 16.04 on VirtualBox

The following is a step-by-step run through for installing Ubuntu 16.04 server as a virtual machine running under a Windows 10 host.  Two prerequisites:

Prepare the VirtualBox VM:

Click on “New” to create a new virtual machine: You’ll get this initial screen to choose the operating system you wish to install and choose a name for the your VM.

The next screen asks what you want to RAM memory. The recommended memory size is 768MB,  but I’ve had decent luck by boosting this to 4 gigs, (on my 8 gig Windows 10 workstation.).

Accept the next suggestion to create a virtual hard disk. The default 8GB is fine, because VirtualBox will expand this if necessary.

Accept the default next screen, to choose the file type.

… and accept the default “dynamically allocated”

Finally you can choose the file size:

In this case,  I chose 16 gigabytes.

Once you have completed the screens above, you need to change two other parameters before starting the actual installation:

Under Settings,  change the networking connection to “bridged adapter”

Under storage, point the little CD image to your .iso file.

Install Ubuntu 16.04

At this point you are ready to start the VM, and go through installing Ubuntu from the .iso file.  This is the standard Ubuntu installation from here on out… run from a  console command line interface. Terminal.jpg

After making your keyboard and language selections, there are several prompts for additional information:

Choose a HostName: UBSandbox

Choose an initial account: larryk

Choose a login name for this account: larryk

Choose a password: mypassword

Encrypt your  home directory?  No

Set your time zone. Setup will suggest your local timezone and then ask
Is this time zone correct?   Yes

Partitioning Method:  Choose “Use Entire Disk”,  don’t worry about LVN

Select Disk to partition…. choose the defaults.

Write changes to disk? Yes

At this point the files are copied to the disk, and the installation continues ore or less on its own for five minutes or so,  then you’ll see a question about the use of an http proxy. This relates to the configuration for the package manager which is used to update the operating system. You can probably ignore this unless you know you are in a corporate environment that uses an http proxy server.

The next screen asks you about updating. I would answer this with the default “no automatic updates”. .

Finally there is a screen that allows you to select additional software packages to be installed. I would include the LAMP server, and the OpenSSH server.  LAMP will be the usual Linux+Apache web server + PHP + mySQL

install.jpg

But wait! There’s more!   You will be asked for a password for the  mySQL database. Ignore this at your peril…and choose the same password as you used for your user account at the beginning of your installation.

At this point the installation will run for a few minutes and then …

Will this ever end?   Accept the default ‘Yes” to install the GRUB boot loader.

grubboot.jpg

And then….  we’re done.

At this point, you should have a working web server that is running an IP address on your network.  To figure out that address. run ifconfig from the VM console.  In our case we’re at 192.168.219.213

ifconfig.jpg

Looks promising.  Now,  we can open a web browser from our Windows workstation (or any other machine on the network, and we should see the Apache web server home screen.

We’re ready install WordPress.  Before doing that however, you might create a snapshot* of the current state of the VM.  This means we will always have a backup of the current machine that we can fall back to as we’re experimenting with installing things. If you haven’t already installed Ubuntu three or four times, you can always delete the whole VM and reinstall if you want to start from square 1.

Install WordPress Using VirtualBox Part 2

Because WordPress is such a popular program, there are tons of resources available. After searching for installing WordPress on Ubuntu Server … I found this page.  I followed all of the instructions, with the two exceptions:

  • I did not configure a static IP address for the sandbox server.
  • I prefaced all commands with sudo.

 Once this was accomplished,  I ended up with the default installation page at:

192.168.219.212/wordpress/

wordpress_install

The first page that comes up is a page which asks for information which will will be written to the wp-config file.   Note that all of the parameters are identical to the ones that were used when setting up the mySQL database in the initial step.

wpsetup

The next page asks for the WordPress site name, and a login password.

wpinstall2

About 30 seconds later, you should see a message that WordPress was installed, and that you can now log in with the name and password that you just created in the last screen.  Do that and the familiar WordPress dashboard will come up.  Hooray!

Install WordPress Using VirtualBox Part 1

Now that we’re WordPress experts,  I’m looking to get an instance of WordPress up and running to be able to experiment.  I’ve been trying this using VirtualBox on Windows 10.  I wanted to create a virtual web server using the latest Ubuntu server 16.04.

  1. Download the .iso file from Ubuntu
  2. Create a new virtual machine, “Ubuntu Server 16.04” within VirtuaBox. I gave it 4 gigs of RAM (half of the physical RAM in my workstation), and excepted all defaults for disk size, etc. The only difference afterwards is to change the Network Adapter from NAT to Bridged.virtualbox1

    3. Install Ubuntu. 
    During the Ubuntu installation, choose the option to install a LAMP server. This includes mySQL, the Apache web server, and the PHP language.

linux_install

4. Once Ubuntu is installed, the server will reboot. You will probably see that there are updates available.  So, to get these run the following commands:

sudo apt-get update
sudo apt-get upgrade

5. Figure out your local IP address:

ifconfig

If this address isn’t on your own subnet, then you can change the network specifications for the VM in VirtualBox from NAT to Bridged Adapter, then reboot the VM.

If all is well so far, you should see the Apache default home page when you type in the ip address into your browser.

apachedefault

At this point, we have a working web server running on our virtual machine.  Now we can actually install WordPress.  My first instinct for this was to use the apt-get method to install the files.

sudo apt-get install wordpress

This appeared to work but didn’t yield a running installation. So after searching I used these instructions to get to get a running WordPress installation.

 

Test PowerShell scripts with VirtualBox

I’m at the point where I am going to deploy some PowerShell scripts to my end-users, and I want to test the scripts on a fresh installation of Windows before trying them on the user’s workstations.

I use VirtualBox to create virtual machines for Powershell testing. Virtual box works on Linux, Mac and Windows host machines. My 8 gig Win 7 box works fine with one or two “guest OS’s”. On my 4 gig (ancient) iMac, it works, but its pretty slow.

One thing that I find amazing, is you have to run updates on all those Windows Virtual machines. Don’t expect to be fully productive on Tuesdays or Wednesdays, when Microsoft sends out Windows updates. It isn’t unusual for updates to run for an hour or more.

Be sure to install the VirtualBox “guest additions” within your Windows VM, once you’ve got your Windows VM up and running. You may also want to change the network settings to “bridged”, so that your VM is on the same network subnet as your host machine.

One other disconcerting thing; your Windows 7 desktop may come up with a black background depending on whether you are running the aero interface and other such fripperies. You can turn all this stuff on if you want; but it will slow down the performance.

More details on setting up VirtualBox are located  here and here.

winvm

If you have installed Windows 7, you may find that it has come with Powershell V.2 out of the box. You can test that by starting a PowerShell session from the command box (just type Powershell.exe).  Once Powershell is up, issue the following command at the prompt:

get-host | select-object version 

If it isn’t 4.0 or later, download the latest version of the Windows Management Framework from Microsoft.
