Virtual Machine Maintenance

Lubuntu

1. Get the latest LTS Lubuntu: ​https://help.ubuntu.com/community/Lubuntu/GetLubuntu
   • currently this is 14.04.1

2. Install it as a new image in VirtualBox
   • accept all defaults
   • US Keyboard
   • username: dev
   • password: eden
   • Login automatically

3. Update

   sudo su -
   apt-get update
   apt-get -y upgrade
   

4. Install dependencies and tools (@ToDo: Make this a downloadable script)

   apt-get -y install vim htop p7zip dos2unix
   apt-get -y install git-core
   #apt-get -y install exim4-config exim4-daemon-light
   apt-get -y install libgeos-c1
   apt-get -y install python-dev
   apt-get -y install python-lxml python-setuptools python-dateutil
   apt-get -y install python-serial
   apt-get -y install python-imaging python-reportlab
   apt-get -y install python-matplotlib
   apt-get -y install python-xlwt
   apt-get -y install build-essential
   apt-get -y install libgeos-dev
   wget --no-check-certificate http://pypi.python.org/packages/source/S/Shapely/Shapely-1.4.1.tar.gz
   tar zxvf Shapely-1.4.1.tar.gz
   cd Shapely-1.4.1
   python setup.py install
   cd ..
   rm -rf Shapely-1.4.1
   wget --no-check-certificate https://pypi.python.org/packages/source/x/xlrd/xlrd-0.9.3.tar.gz
   tar zxvf xlrd-0.9.3.tar.gz
   cd xlrd-0.9.3
   python setup.py install
   cd ..
   rm -rf xlrd-0.9.3
   apt-get -y install eclipse-platform
   apt-get clean
   exit
   

5. Install Web2Py & Eden

   cd
   git clone git://github.com/web2py/web2py.git
   cat << EOF > "/home/dev/web2py/routes.py"
   #!/usr/bin/python
   default_application = 'eden'
   default_controller = 'default'
   default_function = 'index'
   routes_onerror = [
           ('eden/400', '!'),
           ('eden/401', '!'),
           ('eden/509', '!'),
           ('eden/*', '/eden/errors/index'),
           ('*/*', '/eden/errors/index'),
       ]
   EOF
   cd web2py/applications
   git clone git://github.com/flavour/eden.git
   

6.Configure Eclipse

• DeveloperGuidelines/Eclipse

7. Configure Firefox
   • Install Firebug: ​http://getfirebug.com
   • Add Bookmarks for Local instance, Eden WIki, Web2Py book, Python docs, etc

8. Run Eden
   • Edit 000_config.py
     • Comment FINISHED_EDITING
     • Set debug = True

9. Add Management Scripts

   sudo su -
   cat << EOF > "/usr/local/bin/clean"
   #!/bin/sh
   cd ~/web2py/applications/eden
   rm -rf databases/*
   rm -f errors/*
   rm -rf sessions/*
   rm -rf uploads/*
   cd ~/web2py
   python web2py.py -S eden -M -R applications/eden/static/scripts/tools/noop.py
   EOF
   chmod +x /usr/local/bin/clean
   exit
   

10. Test

11. Cleanup

Prepare for upload by cleaning up the disk as much as possible:

• Delete Firefox History

  cd ~/web2py
  rm httpserver.log
  cd ~/web2py/applications/eden
  rm -rf databases/*
  rm -f errors/*
  rm -rf sessions/*
  rm -rf uploads/*
  sudo su -
  apt-get clean
  dpkg -l | grep ^rc | awk '{print $2}' | xargs dpkg -P
  rm -rf /tmp/*
  rm -rf /var/tmp/*
  rm /var/log/*
  

TurnKey Linux

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
