This tutorial illustrates how to setup a Ubuntu server for Moodle and VPL. The main Ubuntu server runs two virtual servers, one a LAMP server that hosts Moodle, the other a regular Ubuntu server used for the jail-system required by VPL.
Hardware Server Setup

[edit]Install/Setup VPL Module
[edit]VPL Module Download from http://vpl.dis.ulpgc.es/index.php/en/download sudo unzip module in /var/www/moodle/mod Go to notification in Admin Menu of moodle, and click on update database. ==> Success! [edit]VPL Jail System Follow the directions at http://vpl.dis.ulpgc.es/index.php/en/documentation/75-how-to-install-vpl-jail-system sudo, go to ~/Downloads and download vpl_jail_system-latest.tar.gz sudo -i cd /Users/dominique/Downloads wget vpl_jail_system-latest.tar.gz tar -xzvf vpl_jail_system-latest.tar.gz cd vpl_jail_system-2.0 ./install-vpl-sh ( yes to certificate) ( yes to development software) ( no to extra development software) ( no to remove apache2) Got some errors, ServerName and not able to bind... Turns out VPL listens to port 80 and 443, which conflicts with Apache2. No wonder it asks if apache should be removed during installation. I guess it's because VPL could be installed on a server that is not a LAMP server... So, edited several files: /etc/hosts: 127.0.0.1 localhost 127.0.1.1 moodleServer
- The following lines are desirable for IPv6 capable hosts
- 1 localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes ff02::2 ip6-allrouters
/etc/apache2/apache2.conf (add at end of file): ServerName localhost
/etc/apache2/ports.conf
- If you just change the port or add more ports here, you will likely also
- have to change the VirtualHost statement in
- /etc/apache2/sites-enabled/000-default.conf
Listen 80 443
reboot ==> now apache works, and can loggin to Moodle [edit]June 4 2014
figured out that VPL jail should be its own virtual server! [edit]Create new Virtual Server: VPLServer
created new Ubuntu 14.04 virtual server on Hadoop0 VPLServer dominique/sevenseas... bridged Network install emacs install VPL server
wget http://vpl.dis.ulpgc.es/releases/vpl_jail_system-2.0.1.tar.gz
select no for wildcard certificates install ddclient (current IP=131.229.102.20) setup vplserver.dyndns.org as name of machine reboot start/stop/start vpl (won't work), reboot and start vpl, and it works!
sudo reboot sudo service vpl-jail-system start
Test. Plug these URL in browser and get OK message in blank page: http://vplserver.dyndns.org/OK https://vplserver.dyndns.org/OK [edit]Update Moodle to use VPLServer
Switch to moodleServer where Moodle is installed login as admin (in the mood password) go to http://moodleServer.dyndns.org/moodle/admin/search.php?query=vpl Set Execution Server List to http://vplserver.dyndns.org

[edit]Error: PHP needs XMLRPC
To test if Moodle sees the VPL server, go to a VPL activity created in a course, and select it. Open it There should be a VPL Administration menu in Moodle opening up. Pick Advanced Settings and Check execution servers to see what happens. I first got PHP needs CMLRPC error, even for the default VPL server set in Spain. Solution: install php5-xmlrpc on moodleServer and vplserver sudo apt-get install php5-xmlrpc
Then repeat the test and see the result of Check execution servers in Moodle:

[edit]Backup
create a backup of the /home/dominique with deja-dup. Just start the "Backup" black vault app in the favorites. output folder is /media/1_5TB/Backups/deja-dup/ Backup performed every day Used Clonezilla to make a duplicate of 1TB boot disk. Now second 1TB contains exact copy and can be booted from. Disks labeled inside the case (Boot/Backup). The backup disk is off line and off power for now. The boot disk has ID WD-WCAU4C220157 The backup disk has ID WD-WCAU4C208949 Used the GUI, but can run this command from Clonezilla shell to go faster:
/usr/sbin/ocs-onthefly -g auto -e1 auto -e2 -j2 -r -f sdb -t sdc
