   wget --no-check-certificate http://pypi.python.org/packages/source/S/Shapely/Shapely-1.4.0.tar.gz
   tar zxvf Shapely-1.4.0.tar.gz
   cd Shapely-1.4.0

   cd xlrd-0.9.3
   python setup.py install
   cd ..
   apt-get -y install eclipse-platform
   apt-get clean
   

4. Install Web2Py & Eden

   cd
   git clone git://github.com/web2py/web2py.git
   

5.Configure

TurnKey Linux

​http://www.turnkeylinux.org/sahana-eden

NB This version is currently far out of date, and not currently in use.

---

It is best if the VM is maintained using the original VirtualBox image & then re-exported to OVF

update_all

Test Sahana Eden.

clean

The following aliases have been setup:

alias w2p='cd /home/sahana/Desktop/web2py && python web2py.py -S eden -M'
alias update='cd /home/sahana/Desktop/web2py/applications/eden && git pull'
alias update_w2p='cd /home/sahana/Desktop/web2py && git pull'
alias update_all='sudo apt-get update;sudo apt-get upgrade -y;cd /home/sahana/Desktop/web2py && git pull;cd /home/sahana/Desktop/web2py/applications/eden && git pull'
alias clean="rm ~/.bash_history;cd ~/Desktop/web2py/applications/eden && rm -f databases/* && rm -rf cache/* && rm -f sessions/* && rm -f models/000_config.py && rm -f cron/crontab;sudo rm -f /var/log/*;sudo rm -f /var/cache/apt/archives/*;COLUMNS=200 sudo dpkg -l | grep ^rc | awk '{print $2} ' | xargs sudo dpkg -P"

General

Resume Uploads

If the scp upload fails, then can resume it using:

rsync -Pe ssh Eden-VM.zip flavour@eden.sahanafoundation.org:.

Info only

The next 2 steps are unnecessary if exporting to OVF?

Overwrite the freespace with zeroes:

• ​http://techthrob.com/2009/03/02/howto-delete-files-permanently-and-securely-in-linux/

  apt-get install secure-delete
  sfill -fz /
  

Compress the VDI disk image:

• ​http://www.mdl4.com/2010/04/virtualbox-compact-a-vdi-in-ubuntu/

  C:
  cd "\Program Files\Oracle\VirtualBox"
  VBoxManage modifyhd c:\Users\%USERNAME%\.virtualbox\harddisks\Eden-Dev.vdi compact
