View source for Installing from WW2.9 Ubuntu14.04 Vanilla Virtual Machine Image

{{Historical}}

<!--  {{UnderConstruction}}  -->

These instructions cover the installation of the Ubuntu Linux 14.04.2LTS 64 bit operating system and WeBWorK 2.9 using the WeBWorK Virtual Machine Image.  

The WeBWorK Virtual Machine Image is an <code>.ova</code> file which is an "open, secure, portable, efficient and extensible format for the packaging and distribution of software to be run in virtual machines" (see http://en.wikipedia.org/wiki/Open_Virtualization_Format) and is supported by VMware, VirtualBox, etc.  This image file has been tested on VMware Player 6 and VirtualBox 4.

This "vanilla" version of the server should work fine for smaller installations (say a 1000 users or less). There will be a "production" version that adds things like lighttpd, log rotations, etc that are useful for larger installations and/or slower servers.  Note that you can always start with the vanilla version and make additions or changes after setting up your server.

== Installing from WW2.9 Ubuntu14.04 Vanilla Virtual Machine Image  ==

===Overview===
After installing from the WeBWorK Virtual Machine Image, you will have a full fledged Ubuntu 14.04 LTS system with WeBWorK, Apache2, MySQL, etc. installed and configured. If your network uses DHCP, networking will be automatically configured for your system. If it uses static IP addresses, you will have to configure networking.  Also it is imperative that you CHANGE THE PASSWORDS for the OS user <code>wwadmin</code> (which has sudo privileges), for the MySQL users <code>root</code> and <code>webworkWrite</code>, and for the WeBWorK user <code>admin</code> which has professor privileges (see below).

There are more detailed instructions for Ubuntu 14.04 and WeBWorK 2.9 at
[[Installation_Manual_for_2.9_on_Ubuntu_14.04]]

===Download the ova image===

There is only a 64 bit distribution.  The 64 bit distribution should work with most modern cpu's. Download the md5 check sum and .ova file from either of the sites below. Download <code>WW2.9_Ubuntu14.04_Vanilla.ova.md5</code> and <code>WW2.9_Ubuntu14.04_Vanilla.ova</code> .  The ova is a 2.2 GB file.

===Installing the WeBWorK Virtual Machine Image ===

Import the file <code>WW2.7_Ubuntu12.04_Vanilla.ova</code> into your virtualization software package (e.g. VMware, VirtualBox). The ova file was created on VirtualBox and has been tested on VirtualBox and WMware Player. Note on WMware Player you will get a warning message but on retry it will work.  After importing, your virtual WeBWorK server will be identical to a system created from the WW2.9 Ubuntu14.04 Vanilla LiveDVD. 

'''Note''' that on other virtual environments, you may need to take additional actions. See the section [[#Other Virtual Environments|Other Virtual Environments]] below.

===Install the Ubuntu package texlive-latex-extra ===

We need to install one extra package that was not included on the WeBWorK Virtual Machine Image. Open a terminal window and run the command
 sudo apt-get install texlive-latex-extra
 [sudo] password for wwadmin: <wwadmin password>

===Continue the installation===
You are exactly at the 
stage in the installation described in [[Installing_from_WW2.9_Ubuntu14.04_Vanilla_LiveDVD#Boot_your_server]].

===Continue Installation ===

Go to [[Installing_from_WW2.9_Ubuntu14.04_Vanilla_LiveDVD#Boot_your_server]] and follow the instructions there. '''Note that if your server will be accessible from the internet, it is imperative that you follow the instructions for changing passwords.'''

===Other Virtual Environments===
Below you will find additional information about installing the ova on other virtual environments.  
 
====VMware's ESXi 5.5 Server====

Jay A. Hightman <jhightman@mbc.edu>, Systems Administrator, Mary Baldwin College reports that it is not possible to directly import the "WW2.9_Ubuntu14.04_Vanilla.ova" virtual machine directly in to 
VMware's ESXi 5.5 Server.  He sent us the following work around.  Thanks Jay.

 
 One gets the following error:

 There are three offending sections in the OVA file, which I have highlighted
 in red:

 A work around is to use the VMware OVF tool to convert the OVA to an VMX image.

 Download VMware Open Virtualization Format Tool 3.5.2

 After doing this, I was able to upload the VMX and VMDK files which were
 created to storage on a VMware ESXi 5.5 Server, import the system, and
 continue the configuration of Ubantu as well as other installed applications
 used by WeBWorK.

 My hope is this information will be useful to you as well as other users of
 WeBWorK virtual machine.
