Setup of an OSGeo Virtual Machine with VirtualBox

Setting up a OSGeo VirtualBox-VM on Lautaro with SuseLinux - but using command line (because creating the VM via the graphical interface vboxgtk did not work properly). The general documentation was taken from here: http://stdioe.blogspot.com/2012/01/creating-virtual-machine-with.html

Steps:

1. install virtualbox on server/computer (done by Daniel, needs admin rights of course)
2. download the iso with the OS, for ubuntu (= not OSGeo live):

   curl -L -O  http://releases.ubuntu.com/12.04.3/ubuntu-12.04.3-server-i386.iso > ubuntu12043server.iso

3. create a VM based on Ubuntu:

   VBoxManage createvm --name osgeo  --ostype Ubuntu --register

4. check it is there:

   VBoxManage showvminfo osgeo

5. set the memory/ram:

   VBoxManage modifyvm osgeo --memory 8192

   (which is 8GB)
6. check the memory/ram:

   VBoxManage showvminfo osgeo | grep "Memory size"

7. set the number of cpu's to use (here 4):

   VBoxManage modifyvm osgeo --cpus 4

8. set the network connection/routing

   VBoxManage modifyvm osgeo --nic1 nat

   Here we use 'nat'-ing instead of a bridge. For a bridge we have to use unstead: first this command: VBoxManage modifyvm osgeo --bridgeadapter1 eth0 and then, this command: VBoxManage modifyvm osgeo --nic1 bridged.
9. create a harddisk of 100GB size:

   VBoxManage createhd --filename osgeo.vdi --size 100000

10. define the VM's disk controller:

    VBoxManage storagectl osgeo --name "SATA Controller" --add sata --controller IntelAhci

11. mount the disk:

    VBoxManage storageattach "osgeo" --storagectl "SATA Controller" --port 0 --device 0 --type hdd --medium osgeo.vdi

12. check if everything is there:

    VBoxManage showvminfo osgeo

13. add DVD device:

    VBoxManage storagectl osgeo --name "IDE Controller" --add ide --controller PIIX4

14. load the DVD device with the Ubuntu VM/osgeo iso file (check if the iso has proper rights, i.e. maybe do a chmod 775):

    VBoxManage storageattach osgeo --storagectl "IDE Controller" --port 1 --device 0 --type dvddrive --medium yyy/osgeolive7.iso 

15. starting VM

    VBoxHeadless -s osgeo -n -m 7777 & 

    The -s is for start, 7777 defines the port for conecting with VNC, and the & is for keeping the VM running when I disconnect from the server. Headless actually means, that we have no monitor...
16. don't forget to install VNC Viewer (e.g. RealVNC), and then connect via the defined port - to "146.155.xx.xxx:7777"
17. ... do a real install of the osgeo VM, etc.
18. install ssh server

    sudo apt-get install openssh-server

19. how to do a mapping for ssh (& ftp), so that the guest VM can be reached from the host machine is described here: http://blogs.oracle.com/rmanus/entry/virtualbox_how_to_ftp_from
    In particular one has to do the following:

    VBoxManage modifyvm osgeo --natpf1 "ssh,tcp,,2222,,22

    These entries are then added to osgeo.vbox xml file. For ftp the port would be 21 instead of 22. To enable Apache, do the same but use: config folder "apache", HostPort "8888", GuestPort "80", Protocol "TCP", e.g. (as one line):

     VBoxManage modifyvm osgeo --natpf1 "apache,tcp,,8888,,80"

    and for Tomcat:

     VBoxManage modifyvm osgeo --natpf1 "tomcat,tcp,,8889,,8080"

    • Note, if a "Error: failed to start machine. Error message: Configuration error: Failed to get the "MAC" value (VERR_CFGM_VALUE_NOT_FOUND)" appears, then it may be necessary to change the network adapter to PCnet-FAST III (Am79C973), according to this Blog entry
20. check here on how to detach the medium use:

    VBoxManage storageattach osgeo --storagectl "IDE Controller" --port 1 --device 0 --type dvddrive --medium none

21. shutting down the vm per vboxmanage :

    VBoxManage controlvm <uuid>|<name> pause|resume|reset|poweroff|savestate|acpipowerbutton|acpisleepbutton

22. tomcat 6 can be found in /usr/share/tomcat6/bin. However, the start/stop command is simply:

    sudo service tomcat6 start

    Check out: Blog: How to instal Tomcat 6 on Ubuntu 12.04. Also, don't forget to create users for the manager interface (see this Blog post). Finally, the right amount of memory can be assigned in the file /etc/tomcat6/tomcat6.conf. However, I did not had this file. So I created a new file setenv.sh in /usr/share/tomcat6/bin via

    sudo touch setenv.sh

    and then edited it adding the following lines:

    #!/bin/sh <new line> JAVA_OPTS="-Xmx2096m -Xms512m -server -Djava.awt.headless=true -Djava.util.prefs.systemRoot=$CATALINA_HOME/content/thredds/javaUtilPrefs" <new line> export JAVA_OPTS

    Then I stopped and re-started tomcat. The above method also worked with Tomcat7.
23. displaying catalina output:

    cd /var/lib/tomcat6

    tail -f logs/catalina.out

24. activate remote desktop for VBox:

    VBoxManage modifyvm osgeo --vrde on

    VBoxManage modifyvm osgeo --vrdemulticon on

    and define the port number

    VBoxManage modifyvm osgeo --vrdeport XXXX

Other Notes

Install & updates

When Installing Ubuntu server, I got actually problems with the update sever, and had to switch to main. For that I used:

sudo nano /etc/apt/sources.list

Then locate http://cls.archive.ubuntu.com/ubuntu and replace it with http://archive.ubuntu.com/ubuntu.
Afterwards, installing htop with sudo apt-get install htop worked as well, why it did not work before.

Installing a GUI

Installing a (optional) GUI for Ubuntu is described here: http://www.maketecheasier.com/use-a-gui-on-a-ubuntu-server/

Changing Vbox mac address

use

VBoxManage modifyvm osgeo --macaddress1 08002783b21e

After that my eth0 disappeared, I got it back by deleting: /etc/udev/rules.d/70-persistent-net.rules and rebooting. This tip came from here.

Next I had to set the IP manually, using command line. How to do this via command line is described here

Changing the max upload size of wars for Tomcat 7

use

/usr/share/tomcat7-admin/manager/WEB-INF$ sudo nano web.xml

and change the max file setting
