Summary

This virtual machine has been built to allow Developers to get operational quickly (1 Gb compressed):

It is in the Open Virtual Machine format for use in either ​VirtualBox or ​VMWare.

It is currently running the Ubuntu 10.04 OS with Web2Py-r2717, Eden-r1560 & Eclipse 3.6.

Usage Notes

Introduction

The dev env virtual machines for Virtualbox and VMware are based on a blueprint and are configured to use about 512MB of RAM. The virtual disk is configured to expand to 20GB. The virtual machine is built on ​TurnKey Linux's Core, which in turn is based on Ubuntu 10.04 (Lucid -- the most recent long-term support release). The machine runs ​Shellinabox, ​Webmin, and SSH/sftp as services from startup.

The development environment is configured to launch ​LXDE, a lightweight desktop environment after the first boot. From LXDE, Eclipse with Pydev, Firefox with Firebug, and irssi are accessible.

Getting Started

1. Download the Image
2. Uncompress the image: ​7zip is a very effective FOSS tool for systems running Microsoft OSs. In Linux distros, the following command should work:

   unzip Eden-VM.zip #unzip to current working directory
   unzip -d ~/ Eden-VM.zip #unzip to home directory
   

To run the image, you need to install either VirtualBox or VMWare:

VirtualBox Installation

3. Download ​VirtualBox
4. Install VirtualBox
5. Import the Virtual Appliance:

• File menu | Import Appliance
• Choose the uncompressed image (the .ovf file)
• Next
• Accept the default appliance options unless you have a reason to make a specific change

6. The VM will appear in the left window pane, and the settings will appear in the right. Scroll down on the right side until you see "Network." Click network to specify the NIC (e.g. switch to wireless) and choose between bridged and NAT mode.
7. Start the Virtual Appliance by double-clicking the icon on the left.

VMWare Installation

To import the download VM into VMware (e.g. Fusion), use the following steps.

3. File > New
4. Click Continue without disc
5. Select Use an existing virtual disk
6. Select NewDev.vmdk
7. Select Make a separate copy of the virtual disk
8. Click Choose
9. Click Continue
10. OS=Linux and Version=Ubuntu should be selected, click Continue, Click Finish 11 Enter name for new VMware image e.g. Eden in the Virtual Machines directory
11. Click Save

Remember to install the Linux VMware Tools after starting up the Eden machine using Virtual Machine > Install VMware Tools

sudo su -
./vmware-install.pl

And accept all the default options

Credentials

After first boot, the machine arrives at the graphical user interface login page. Login with the provided credentials.

Web2py administration password is set during the debugging process with either of the following commands and arguments, both of which would set the admin password to "admin":

/home/dev/web2py.py -a admin -i 127.0.0.1 -p 80

/home/dev/web2py.py --password admin -i 127.0.0.1 -p 80

Root User

Username: root

Password: to be determined

Dev User

Username: dev

Password: eden

Filesystem

Web2py is located in /home/web2py. Eden is located in /home/web2py/applications/eden. Eclipse and PyDev are preconfigured with this information.

Scripts

/usr/local/bin contains three helpful scripts. To run them, start LXTerminal (in the accessories menu) and simply enter the commands as demonstrated below. They are in all users' paths, so may be executed from any working directory.

Update web2py

Enter the command with or without a revision number, as demonstrated below:

update_web2py 2717 #updates web2py to rev 2717
update_web2py #updates web2py to recent revision

Import Eden

update_eden 1560 #updates Eden to rev 1560
update_eden #updates Eden to recent revision

Update Eden

Imports Eden to Web2py

import #imports models to web2py

Troubleshooting older Releases

Note: If you get a ticket when running the application for the 1st time with a message like "OperationalError: Cannot add a UNIQUE column" then you need to stop the debugger, delete the contents of the databases folder & then start debugging again (there was an old database accidentally left on the system which cannot be auto-migrated - a new image without this issue has been uploaded):

rm -rf ~/Desktop/web2py/applications/eden/databases/*

If you get an error like "AttributeError: SQLCustomType instance has no attribute 'startswith'" then:

cd ~/Desktop/web2py/gluon
rm sql.py
wget http://eden.sahanafoundation.org/sql.py

Then can proceed as above: Stop Eclipse, empty databases folder & restart Eclipse

A new image without this issue has now been uploaded.
