How to build a WormBase Virtual Machine
Establishing the Virtual Machine
Installing the OS
Preparing the system for a WormBase installation
Installing the WormBase core files
Preparing a VMX for release
1. Start the guest OS.
2. In the guest, purge things like access logs, tarballs, etc
3. Shrink the disk in the disk by first zeroing empty space
sudo dd if=/dev/zero of=/empty_file rm /empty_file
4. Set the VMX to graphical runlevel 5 (/etc/inittab)
5. Shutdown the guest
6. Copy the current wormbase-live to a directory named by release:
cp -r wormbase-live wormbase-WSXXX.YYYY.MM.DD
7. In the console, set the version and release date
WormBase (WSXXX; DD Feb YYYY)
8. Defragment the disk from the VMWare console:
Edit options > Hard Disk > Defrag the disk
9. In the VMWare console, set networking to NAT (assume desktop usage) and restart the guest.
10. Start the new VMX.
11. Reset the MAC address
12. Finish shrinking the disk using the vmware-toolbox:
$ vmware-toolbox (select shrink)
13. When complete, shut down the VMX
tar czf wormbase-WSXXX.YYYY.MM.DD.tgz
15. Symlink to make it available via http
cd /usr/local/wormbase/html/vmx ln -s /usr/local/vmx/wormbase-WSXXX.YYYY.MM.DD.tgz wormbase-WSXXXX.YYYY.MM.DD.tgz
16. Upload the new VM to BitTorrent
17. Update the [[Virtual_Machines Virtual Machines] page on the Wiki
Configuring VMXs as hosted frozen releases
To use a Virtual Machine as a server, a few small modifications need to be made.
1. From the VMWare Server console, launch the virtual machine
2. Set a static IP (must be assigned!)
In this example, the guest OS IP is 220.127.116.11. This should be changed to whatever your assigned IP address is.
ifconfig eth0:0 18.104.22.168 netmask 255.255.255.0 broadcast 22.214.171.124 route add -host 126.96.36.199 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: 188.8.131.52 Broadcast host: 184.108.40.206 (not explicitly set in the GUI)
3. 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"
4. Add the following lines to /etc/resolve.conf for DNS
search cshl.edu nameserver 220.127.116.11 nameserver 18.104.22.168
5. 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:
6. Edit /usr/local/wormbase/conf/localdefs.pm and httpd.conf with the appropriate hostname
7. Place the VM into console mode:
sudo emacs /etc/inittab
Make sure that the following lines are commented as indicated:
Or via the command line:
$ 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
8. 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
