"Virtual Machines" (or VMX) are self-contained packages of everything you need to use WormBase locally
Virtual machines can be "played" on Mac, Windows, and Linux platforms using the free VMPlayer (Linux, Windows) or the (non-free how do you like them apples?) VMWare Fusion Player (Mac) available from VMWare.
To keep downloads as reasonable as possible, we've split virtual machines into two components. First, you will need the primary virtual machine, which contains the WormBase software, within a Linux operating system.
Once you have the software, you can download the datasets you are interested in. We supply these as "virtual disks" -- consider these removable disks exactly like you might have sitting next to your laptop. Download only what you need, such as C. elegans predictions, WormMart, etc, although to keep things simple, we recommend you download everything.
Running a virtual machine of WormBase is incredibly easy.
- Download the VMPlayer from VMWare
- Download a WormBase virtual machine
- Select the datasets you'd like to use and download them
- Open the virtual machine using VMPlayer or VMFusion
- Log in
- A browser launches automatically and takes you to your copy of WormBase!
- Mac (with Intel chips), Windows, or Linux computer
- Virtualization Player (free): VMPlayer (Linux/Windows); (non-free) VMWare Fusion (Mac)
- 1.5 GB free memory (2GB recommended)
- 30 - 50 GB free disk space
Available Virtual Machines
WormBase virtual machines are preconfigured for use on the desktop. This means that they are intended to be run and used on the same local machine. If you would like to run the virtual machine as a server you will need to make some small changes to the configuration. See the section "Running a WormBase Virtual Machine as a server" for additional details.
Please see the WormBase FTP site for available virtual machines.
Downloading via the command line client curl
1. Open a terminal window
2. Type the following commands
curl -O http://www.wormbase.org/vmx/WS150.vmx.tgz curl -O http://www.wormbase.org/vmx/WS150.vmx.tgz.md5 md5sum --check WS150.vmx.tgz
Fetching new releases automatically
WormBase creates new virtual machines for every release of the database. Your computer can fetch these for you automatically using the following script.
forthcoming - this script is still under development
Unpacking a downloaded torrent
Once you've completely downloaded one of the releases, unpack it using tar/gzip. I've had bad luck extracting the file with things like the BomArchiveHelper.
prompt> ls -rw-rw-r-- 1 todd todd 8.5G Mar 8 13:06 wormbase-WS171.2007.03.04.tgz prompt> tar xzf wormbase-WS171.2007.03.04.tgz
Note: Do make sure that you have 30-50 GB of disk space free prior to unpacking!
Using a WormBase Virtual Machine
Starting the Virtual Machine
Launch your Virtual Player / VM Fusion. From the File menu, select "Open". Navigate to the unpacked directory of the WormBase Virtual Machine. Open it. Inside, you will find a file ending with the suffix ".vmx". Select it, then select OK. The Virtual Machine will start to boot up.
Log in as
User: wormbase Pass: wormbase
After logging in, a browser window will appear taking you directly to your local copy of WormBase.
Each WormBase Virtual Machine contains the entirety of WormBase. This makes it a great tool for tasks like data mining. You can also use individual components of WormBase to best suit your needs.
Xace - the graphical interface to AceDB
Tace - the text interface to AceDB
AcePerl - Perl API to AceDB
Mine the underlying AceDB database programmatically using AcePerl.
Bio::DB::GFF - Perl API to genomic annotations
Each virtual machine contains multiple mysql databases of genomic annotations, including (as of WS170, 2/2007), C. elegans, C. briggsae, and C. remanei. You can use the Bio::DB::GFF API -- part of BioPerl -- to easily mine these sequence annotations.
Updating the Software
Itins 't necessary to download a new Virtual Machine for every release of the database. To keep your virtual machine up-to-date, just leave it running over night. It will automatically fetch new software every evening. If you would like to do this manually, open a Terminal and run the following command.
Note that you still need to download the databases for each new release!
I've set up a very low traffic mailing list for users interested in running WormBase locally. Please subscribe. I promise I won't spam you.
Running a WormBase Virtual Machine as a server
Each WormBase Virtual Machine contains everything that you need to run it as a standalone server. In server mode, you can install a single copy of WormBase locally and make it available to others in your lab or organization, or even establish your own local mirror of WormBase accessible to all.
To do this, you will need to modify a few settings of the virtual machine. The main consideration for running a virtual machine as a server is how to manage networking. Described below are the two most suitable approaches. Bridged networking is the easiest and requires no additional components.
Using a VM with bridged networking
When run in bridged networking mode, the VMX shares the host OSs internet connection. This allows the guest OS to run with its own domain name and IP address.
1. Acquire a static IP and suitable domain name for your virtual machine
2. When launching the virtual machine, for networking, select "Bridged".
3. Configure network settings with your IP, domain name, and subnet mask.
In this example, the guest OS IP is 22.214.171.124. This should be changed to whatever your assigned IP address is.
ifconfig eth0:0 126.96.36.199 netmask 255.255.255.0 broadcast 188.8.131.52 route add -host 184.108.40.206 dev eth0
You can also do this from the GUI if you prefer, under System Settings -> Network. Double click on the network adaptor.
Address: Your assigned IP address Subnet mask: 255.255.255.0 Default gateway: 220.127.116.11 Broadcast host: 18.104.22.168 (not explicitly set in the GUI)
4. Reset the MAC ID of the guest
System Tools > Network
Double click on the network adaptor and select the "Hardware" tab. Click on "Probe", then "OK"
5. Add the following lines to /etc/resolve.conf for DNS. For our example, these are:
search cshl.edu nameserver 22.214.171.124 nameserver 126.96.36.199
6. Set the hostname
This can be done either in the GUI under the Network panel, or using the following command line terms.
If you have a static IP address, then /etc/hosts is configured as follows:
127.0.0.1 localhost.localdomain localhost 143.488.220.44 mybox.mydomain.com mybox
After updating the /etc/hosts file correctly, the "hostname" command should be run as follows to set your hostname:
7. Edit /usr/local/wormbase/conf/localdefs.pm and httpd.conf with the appropriate hostname as necessary.
8. Place the VM into console mode:
Comment out the runlevel 5 directive and uncomment the id3 runlevel directive in /etc/inittab:
$ sudo perl -p -i -e 's/id:5:initdefault:/#id:5:initdefault:/' /etc/inittab $ sudo perl -p -i -e 's/#id:3:initdefault:/id:5:initdefault:/' /etc/inittab
9. Shutdown the virtual machine and copy it as a backup
I append "server" to the name to indicate that it is configured as a server
tar czf wormbase-WS100.2003.05.13-server.tgz wormbase-WS100.2003.05.13
10. Restart the Virtual Machine. You should be good to go!
Using a VM with NAT addressing
By default, WormBase virtual machines use NAT networking. If you would like to use a server in NAT mode, you will need to configure an upstream proxy server (Apache or Squid, for example) to access the virtual machine remotely.
Resetting the MAC address
MAC addresses are set automically in virtual machines based on the host OS name and the path to the .vmx file on the host OS. If you move the virtual machine, the MAC address will be incorrect.
When booted into graphical mode:
System Tools > Network
Double click on the network adaptor and select the "Hardware" tab. Click on "Probe", then "OK".
