This virtual machine has been built to allow Developers to get operational quickly (1 Gb compressed):
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.
- Download the Image
- 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:
- Download VirtualBox
- Install VirtualBox
- Import the Virtual Appliance:
- File menu | Import Appliance
- Click on the Choose button and navigate to and select the uncompressed image (the .ovf file)
- Accept the default appliance options unless you have a reason to make a specific change
- 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.
- Start the Virtual Appliance by double-clicking the icon on the left.
Solutions will be here.
Too Many IDE Drives Configured
Scenario: After first step of import, VirtualBox OSE reports the following: "Failed to import appliance /path/to/appliance/NewDev.ofg. Too many IDE controllers in OVF; import facility only supports one." Solution: Pending.
To import the download VM into VMware (e.g. Fusion), use the following steps.
- File > New
- Click Continue without disc
- Select Use an existing virtual disk
- Select NewDev.vmdk
- Select Make a separate copy of the virtual disk
- Click Choose
- Click Continue
- OS=Linux and Version=Ubuntu should be selected, click Continue, Click Finish
- Enter name for new VMware image e.g. Eden in the Virtual Machines directory
- Click Save
- Press the green play icon to start the virtual machine.
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
Troubleshooting VMware Tools Install
- Open LXTerminal and browse to the folder containing vmware-install.pl.
pwd #displays the current location in the filesystem cd /absolut/path/to/folder # change directory to the one containing vmware-install.pl sudo ./vmware-install.pl #start installation script
- Download Build Tools
*Option 1: Open Synaptic in the LXDE menu, update, then search for build-essential
*Option 2: Open LXTerminal and install build-essential from the command line:
sudo apt-get update sudo apt-get install -y build-essential
After first boot, the machine arrives at the graphical user interface login page. Login with the credentials provided below.
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
|Username: dev||Password: eden|
|Username: root||Password: root|
There is no practical reason to login in as root.
If one needs root privileges, dev can have them. The following lines offer strategies for escalating devs privileges from the command line. Start LXTerminal and use one of the following strategies.
sudo command-to-execute-as-root #executes on command or pipeline of commands as root. su - root #Switch user to root command to execute #1 command executed as root command to execute #2nd command to execute as root command to excecute #3rd command to execute as root exit # Exit using root's account and shell
Secure the System
Change the default passwords to secure the system. Log in as dev, start LXTerminal, and enter the following commands to change passwords:
sudo passwd root #interactive change root password passwd #Interactive change dev password
It's also important to keep get security updates from online; login as dev and execute the following:
sudo apt-get update sudo apt-get upgrade
Web2py is located in /home/web2py. Eden is located in /home/web2py/applications/eden. Eclipse and PyDev are preconfigured with this information.
/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.
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
update_eden 1560 #updates Eden to rev 1560 update_eden #updates Eden to recent revision
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.
