Instructions for creating a WeBWorK Amazon Machine Image (AMI)
Build the server on VMWare Workstation Player
- 12 GBk disk (single file)
- 4 GB memory
- 2 cpu
The above resources are small.
- 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
Workstation Player
When you see REBOOT, reboot and login (wwadmin/wwadmin)
Do not accept any updates (save disk space)
Check if tools are installed
vmware-toolbox-cmd -v
(they should be) and if so, remove them
sudo apt remove open-vm-tools sudo apt autoremove
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
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
link/ether 00:0c:29:4f:2c:1d brd ff:ff:ff:ff:ff:ff inet 192.168.204.128/24 brd 192.168.204.255 scope global dynamic ens33
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 192.168.204.128
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).
Follow the standard instructions
site.conf and localoverrides.conf
- use the ip address (e.g. 192.168.201.128) everywhere. Do not use localhost
- set password for webworkWrite (wwadmin)
set up MyTestCourse
- add practice users and jsmith/jsmith to myTestCourse
- add profa
- add the standard sets to myTestCourse
