Setup of CartoDB VM

Setup of VM based on Basic Ubuntu1404 VM

1. copying basicubunutu1404.vdi file and renaming to cartodb.vdi
2. creating the cartodb VM on CedeusDB (ip.18):
   • VBoxManage createvm --name cartodb --ostype Ubuntu_64 --register
   • VBoxManage modifyvm cartodb --memory 8096
   • VBoxManage modifyvm cartodb --cpus 6
   • VBoxManage modifyvm cartodb --nic1 nat
   • VBoxManage storagectl cartodb --name "SATA Controller" --add sata --controller IntelAhci
   • assign the (old) disk image a new uuid

     VBoxManage internalcommands sethduuid cartodb.vdi

   • attach the (old) disk image:

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

   • VBoxManage storagectl cartodb --name "IDE Controller" --add ide --controller PIIX4
   • set the nat rules (ports):

     VBoxManage modifyvm cartodb --natpf1 "ssh,tcp,,19022,,22"

     VBoxManage modifyvm cartodb --natpf1 "apache,tcp,,19080,,80"

     VBoxManage modifyvm cartodb --natpf1 "pgsql,tcp,,19432,,5432"

3. optional - set VRDE port:
   • VBoxManage modifyvm cartodb --vrdeport 7763 (Note: 3389 is the default port anyway)
4. check all settings with VBoxManage showvminfo cartodb
5. start the VM

   VBoxHeadless -s nominatim --vrde on &

   the VM will listen on port 7763 - connect with GTKvncViewer to check

   • check if ssh connection works
6. change the computers name in /etc/hosts and /etc/hostname
7. restarting Apache gives the error message: "apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 ..."

   => solve this by adding ServerName nominatim as the last line in /etc/apache2/apache2.conf file

Resize the CartoDB VM

• shut the VM down to resize the HDD if necessary
• check the HDD size: VBoxManage showhdinfo cartodb.vdi returns:

UUID:           e148d758-00ac-4b60-a067-d5c97316069d
Parent UUID:    base</br>
State:          created
Type:           normal (base)
Location:       /home/ssteinig/cartodb.vdi
Storage format: VDI
Format variant: dynamic default
Capacity:       100000 MBytes
Size on disk:   6224 MBytes
In use by VMs:  nominatim (UUID: be795392-3786-4f3b-9714-a9445f91855d)

• so I resized the disk to 200GB as, according to Nominatim infos the disk size for a full planet is 700GB

  VBoxManage modifyhd cartodb.vdi --resize 200000

• to make this resizing effective I actually have to change the partitions:
  • create a zip-copy of the vdi file,
  • download & start the VM with Ubuntu Desktop(!) 14.04 iso
  • choose the "Try Ubuntu" mode
  • use the program "gparted" to adjust/extend the partition's size
  • to be able to enlarge "extended" partition, on needs to click on the key symbol and chose "deactivate", as described for instance here: http://www.howtogeek.com/114503/how-to-resize-your-ubuntu-partitions/
  • on 12.04 when extending GeoNode1204 VM: one may also need to extend /dev/sda2 (cyan color) first before extending /dev/sda5 (brownish color)
  • remove the "iso" and restart the Vm; check size if the disks is really 200GB now
  • => Well it turned out that I used LVM (Logical Volume Manager) so the new space is not taken into account. Some more stuff needs to be adjusted!
    • after a bit of reading here: http://www.rootusers.com/how-to-increase-the-size-of-a-linux-lvm-by-expanding-the-virtual-machine-disk/ and here: http://www.thegeekstuff.com/2010/08/how-to-create-lvm/ and checking the status with commands such as pvscan, pvdisplay and lvdisplay; I figured that I simply need to extend the size of the logical volume (see also http://serverfault.com/questions/501895/used-vgextend-lvextend-to-add-addtional-8gb-space-but-it-is-not-reflected-in-df ) This is done with lvextend - so I used:
    • sudo lvextend -l +100%FREE /dev/basicubuntu1404-vg/root
    • sudo resize2fs /dev/mapper/basicubuntu1404--vg-root

    => this extended the disk to 187GB (see with sudo lvdisplay). The second command is needed to have this really available (see with df -h or sudo fdisk -l)
