Installing CartoDB for CEDEUS

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)
