Create WeBWorK Virtual Machine (.OVA) File
Instructions for creating a WeBWorK Virtual Machine (.OVA) Image
Note that the resulting .ova image can be used to create a virtual machine
Build the server on VMWare Workstation (Player or Pro)
- 4 GBk disk (single file)
- 1 GB memory
- 1 cpu
The above resources are very minimal and correspond to a AWS t2-micro level machine which is free.
- Download the ubuntu live CD (server version)
- Install following the standard directions with the following options
- Don't partition disks separately
- User name: wwadmin
- login: wwadmin
- password: wwadmin
- Computer name: wwserver
Do not install VMWare tools
Do not reboot the system - first remove VMWare tools More details on this.
Then boot. After system boots check that openssh-server is installed run
sudo lsof -i -P -n | grep LISTEN
to check if it is listening on port 22 If not install openssh-server
sudo apt install openssh-server
Now on the host set up port forwarding. Find the ip address of your guest The Guest IP is the IP address your guest WeBWorK server is using. You can find it (after you login) by entering the command
$ ip address show
and looking at the output, something like "inet 10.0.2.15/24 ..." (not the LOOPBACK inet 127.0.0.1/8 address). Here the ip address is 10.0.2.15.
Find or download the vmnetcfg.exe program. This does not come with Workstation Player but it does come with Workstation Pro. Download Workstation Pro (Do not install it) and look for this program where you installed things. Run the command as root (or administrator on Windows)
and configure NAT for port forwarding. Say localhost:2222 to e.g. 10.0.2.15:22
Login from Terminal program
At this point you can login to your server from your host machine using SSH (non secure telnet and FTP are not allowed but secure SSH and SFTP are) using your favourite terminal emulator program. E.g. set your terminal to connect to localhost:2222
You can do all of the remaining installation from a terminal emulator on your host. The advantage of doing this is that you can copy commands from these instructions (with copy from the Edit menu or ^C) and paste them into a terminal window (with paste from the Edit menu list or <Shift> <Ctrl> <V> or <Shift> <Insert> depending on your application).
- set password for webworkWrite (wwadmin)
- add practice users and jsmith/jsmith to myTestCourse
- add the standard sets to myTestCourse
- implement all options A-E except C (run WW through SSL)
sudo apt remove openssh-sftp-server
Export to an .ova file.
Find the path to your VM Open a command prompt as administrator cd D:\program files\vmware\vmware OVF_Tool Enter type ovftool “C:\the path to your VM\your VMname.vmx” c:\new directory\name.ova
