Screencast / Video of an Install of OpenStack Essex on Ubuntu 12.04 under VirtualBox

A 12 minute screencast showing an installation of OpenStack ‘Essex’ on Ubuntu 12.04 running on VirtualBox

OpenStack Essex Installation Screencast

OpenStack Essex Installation Screencast

Note that this screencast has no sound.

  1. Configure VirtualBox with the following
    Network Interfaces:
    eth0 (nat)
    eth1 host-only: 172.16.0.0/16
    eth2 host-only: 10.0.0.0/8
    Memory: 1536Mb
    Hard Disk: 20Gb
    System Processor (optional but recommended): Increase CPU from 1
  2. Install Ubuntu 12.04, specifying eth0 as your default interface
  3. Configure networking:
    eth1 is your public network set to be 172.16.0.0/16
    eth2 is your private VLAN
  4. Run an update on the machine, and reboot
  5. Install Git which allows you to pull down a script to perform the installation of OpenStack
  6. Grab the script using the following:
    git clone https://github.com/uksysadmin/OpenStackInstaller.git
  7. Ensure you’re running the ‘essex’ version of the script by running: git checkout essex
  8. Run the script with the following:
    ./OSinstall.sh -F 172.16.1.0/24 -f 10.1.0.0/16 -s 512 -t demo -v qemu
  9. Upload an image using the test supplied script:
    ./upload_ubuntu.sh -a admin -p openstack -t demo -C 172.16.0.1
  10. Log into the Dashboard: http://172.16.0.1/ with ‘demo/openstack’
  11. Create your access keys
  12. Edit the default security group (add in SSH access and ability to ping)
  13. Launch your instance
  14. Log into your new instance!

  5. Hi Kevin!

    Thanks for the walk through!

    I was trying to set this up at home, and came across an issue with glance, when the glance database was empty and no images were showing.

    I found the explanation in this URL, at the bottom, being a 12.04 specific issue:
    http://docs.openstack.org/trunk/openstack-compute/install/content/configure-glance-files.html

    Once I ran the two commands:
    glance-manage version_control 0
    glance-manage db_sync

    The images page loaded without issues.

    Reply

  6. I also needed to add the flag:
    –my_ip=172.16.0.1

    To /etc/nova/nova.conf for the instances to properly reach their metadata at boot time, otherwise they spawned correctly but were not accessible via ssh.

    So now it works! Thanks a lot!

  7. I’m kind of new with OpenStack and Linux servers…I have to test the OpenStack soluton for my school project. I followed this steps and screencast and I can’t get throuh without problems-over and over again 🙂
    When I upload ubuntu image with this command ./upload_ubuntu.sh -a admin -p openstack -t demo -C 172.16.0.1, it looks like it uploads fine, except that don’t get Glance id(?) in the brackets…the message looks like this: “ubuntu 11.10 i386 now avaliable in Glance()”. And when I log-in to dashboard, under Project->Images & Snapshots I get two errorr msgs: “Error: Unable to retrieve images.” and “Error: Unable to retrieve snapshots”. And under images I can’t see ubuntu image as in screencast.
    I would appreciate any suggestion and help how to solve my problem. 🙂
    Thanks!

  11. Hello,

    I have just tried installing OpenStack following your guide but there were a few errors. Here is the complete output of the installation script: http://pastebin.com/GpSqVzgV

    It looks like there is something wrong with the MySQL installation/setup. Can you take a look at this? Thanks!

  12. Hi.
    I follow your video tutorial and when I go to the dashboard I can’t see the images I’ve upload, I’ve this messeage: “Unable to retrieve image” and I’ve the same problem when I go to the Snapshots&Images site.
    Can you help me? Thanks!! and sorry for my english(i’m spanish)

    • I’m noticing this as well. The installation / script executed without noticeable errors, however I’m getting errors with the web interface about images, snapshots and the like. I’ve tried restarting the services, rebooting, and re-installing altogether on a separate system but still seeing the issue.

      Would love any pointers.

    • I’ve uploaded a fix now which you can pull down.

      Quick fix though (replace 172.16.0.1 with the address of your controller box)

      CC_ADDR=172.16.0.1
      cd /etc/glance
      sed -i “s/%CC_ADDR%/$CC_ADDR/g” *.*
      restart glance-api
      restart glance-registry

      • Thanks Kev that works!!!! 😀
        I have another issue, when I go to project and I select Container I get an exception with the code 111. Can you help me please! Thanks!!!!

      • The Container section is “Swift” – The easiest thing to do here is to follow these instructions for an All-In-One Swift install the same box: http://swift.openstack.org/development_saio.html
        I do have a script I use – it’s not the most graceful of scripts to unleash on the public – but it is just an amalgamation of all the steps on that page. Once its there you can then upload/download objects in Swift using Horizon.

      • When I upload the ubuntu image I can’t see it in the dashboard I have no error but the image is not there

      • Hmm, very odd. The fix I put in should have fixed this. When the script you may have noticed that you never got an ID back (you’ll see ubuntu 12.04 amd64 now available in Glance () instead of ubuntu 12.04 amd64 now available in Glance (5f53f5d0-f22a-42e8-a52c-315cbd7517ad). The script needs to actually fail when that’s the case as when running the glance commands actually do return an error. Ensure your /etc/glance config files have nothing in them that looks wrong (like the CC_ADDR I had left in there for example)… correct any problems and restart glance-api and glance-registry.

  14. Kev I launch an image but when I go to the VNC console I get this messeage “If VNC console is not responding to keyboard input: click the grey status bar below.” and my keyboard not respond, and when I try to connect with the instance with ssh I’ve got an error with the public key. Can you help me please. Again I really thank you!!!

    Reply

  15. The Ubuntu images won’t let you log in using the console – the ubuntu user doesn’t have a password set, so its a key-only entry for the cloud image.
    On a command line do the following:

    ssh -vvv -i your_private_key.pem ubuntu@instance_ip_address

    This will give more verbose output and will tell you if your key has been rejected.
    For SSH key access ensure your_private_key.pem is only readable/writeable by you: chmod 0600 (or chmod 0400 for r/o) – either way make sure no group or world readable attrs are assigned. Then try again.

  18. Hey Kev I’ve a problem, I’m trying to make an instance of an ubuntu desktop cluod image, the server give me the two ip’s but suddenly the status turns to error I think that’s a problem of free space of my hard disk. Help me please. Thank you!!! : )

  20. There is a bug in your script. When you run a node or compute install, it sets CC_ADDR=””
    I commented it out, but it might cause confusion for other people trying to use this.

  21. I tried to terminate instance through OpenStack dashboard but I think there is sth wrong. The instance is stuck in deleting process. Does someone have any sugestions how to solve the problem? Thanks…

    Reply

    • Best thing to do (as root) tail /var/log/nova/nova-compute.log. Also try terminating using the command line too (grab the resource file, source it into your shell) then run “nova list” then “nova delete ” to see if its a problem with your install or just with the dashboard.

  22. Hi Kevin, when I launch the instance it finish with status=error and task=spawning. When I look through the nova-compute.log, it fails when it spawns the instance:

      • Perfect! It worked. Thank you Kevin. Now I’m gonna dig into the magic world of OpenStack and its instances!

        Cheers

  23. Hi Kevin,
    Thanks a lot for the nice article, it worked fine until one point, i got stuck where it says “Extracting templates from packages 100%”, after executing ./OSinstall.sh command..
    Is it getting any files from the internet at that point? My system monitor doesn’t indicate any upload/download action ..
    Any idea.. ?

    Thanks

  26. Hi Kevin,
    A nice post indeed.. It helped me a lot.
    Am very new to OpenStack. I followed screen cast as it is. There was no error but now when I log into the web interface, am unable to see any image under project > Images & Snapshots tab. Where as it shows an image under Admin > Images tab.
    Where did I go wrong? I would appreciate any help from you. 🙂

    • Sorry I’ve been silent. Been busy.
      I’ll have to look at the script again – I’ve not had to use it to spin up environments in recent weeks.
      It sounds like there is an issue with the ubuntu upload script. Delete the /tmp/__upload directory and try again.
      The script should produce a uuid for the image – if it doesn’t – put a set -x in the script and debug.

  29. To configure netywork on ubtuntu (step 3.). Is it what we have to define in file /etc/network/interfaces ?

    iface eth1 inet static
    address 176.16.0.0
    netmask 255.255.0.0

    iface eth2 inet static
    address 10.0.0.0
    netmask 255.0.0.0

  30. All the procedure has been followed according to Screencast video and works fine except when I click on “launch instance” button of the “Launch instances” screen that we would like to create. In this case, I get this error message (Error: Unable to launch instance: Can not find requested image (HTTP 400)). My ubuntu image is “ubuntu 12.04 amd64 Server”. In your screencast, it is a Ubuntu release 11.

    • Hi,

      Thank you Kevin, for the detailed info. I am running into this (Error: Unable to launch instance: Can not find requested image (HTTP 400) as well, while trying to lauch an instance from dashboard. Appreciate any pointers. The image is “ubuntu 12.04 amd64 server”. I can see the image on the dashboard. Also not sure if the db is setup correctly. I only see the following db’s and the db “db” has not tables in it:

      mysql> show databases;
      +——————–+
      | Database |
      +——————–+
      | information_schema |
      | test |
      +——————–+
      2 rows in set (0.00 sec)

      • Sorry, earlier I meant to say that the db “test” has no tables in it.
        I assume that is the db “test” is created as a part of this openstack installation. Thanks.

      • Hi,
        This database has no OpenStack databases in – so something more serious has occurred – like not having the correct permissions to create them. The test database is installed by default in MySQL under Ubuntu.
        Check your installation as I’m surprised you can get as far as Horizon…

  31. Hi, I wonder if you can help? I followed the instructions but when I go to 172.16.0.1 I get page not found, but if I install lynx (text browser) on the Ubuntu server and goto lynx 172.16.0.1 I get the admin page.

    Could I just check that with :

    Run the script with the following:
    ./OSinstall.sh -F 172.16.1.0/24 -f 10.1.0.0/16 -s 512 -t demo -v qemu

    172.16.1.0 should be 172.16.0.1 to match the network card setup?

    I used:

    /OSinstall.sh -F 172.16.0.1 -f 10.1.0.1 -s 512 -t demo -v qemu

    Many thanks

    • Given that you’re specifying qemu – I am assuming you’re setting up a test environment? In which case, you don’t need to configure 512 hosts – reduce this to 64:
      Set up 2 nics – eth0 will be the public, eth1 will be private:

      ./OSinstall.sh -F 172.16.0.0/24 -P eth0 -f 10.0.0.0/24 -p eth1 -s 64 -t demo -v qemu

      If this is under VirtualBox – bump up the nics, so eth0 is the NAT, eth1 is the Public and eth2 is Private – and adjust the command line accordingly.
      The -h gives you a help screen.

      This will, by default, install an “All-In-One” and try its best to guess the IP address to configure certain things from the box itself (by looking at what IP address has the default route on).

      One final note – this code has had very little love recently. There are better ways of getting OpenStack installed – such as Rackspace’s Private Cloud Edition.

      Regards,
      Kev

  32. Hi,

    Please can I ask why this command uses:

    ./OSinstall.sh -F 172.16.1.0/24 -f 10.1.0.0/16 -s 512 -t demo -v qemu

    Where all the addresses used elsewhere in the tutorial use 172.16.0.1 and 10.0.0.0

    Also, what does the ‘/’ signify?

    eth1 host-only: 172.16.0.0/16
    eth2 host-only: 10.0.0.0/8

    In the video these do not seem to be typed in when setting up the networks on VirtualBox.

    Best wishes and thanks in advance.

    • Hi Peter – the notation is CIDR: http://en.wikipedia.org/wiki/CIDR_notation.
      So in the above you have 172.16.1.0/24 which means you can have 255 address (give or take an address for network and broadcast). In other words, 172.16.1.25 is part of that subnet, but 172.16.53.25 isn’t as a /24 gives you wriggle room in the final octet. A /16 gives you access to the 3rd octet (e.g. 10.0.X.Y for /16 vs 10.0.0.X for /24) to play with.

      So those options define networks, not individual addresses.

  36. Hello Kev,
    It seems that the following the repository (https://launchpad.net/api/1.0/~openstack-core/+archive/trunk) extracted from OSinstall.sh script doesn’t work anymore. When I launch the script it display this error:
    Cannot access PPA (https://launchpad.net/api/1.0/~openstack-core/+archive/trunk) to get PPA information, please check your internet connection.

    But the rest of installation continue except that when I create and launch an instance, I cannot login using this command : ssh -i demo.pem ubuntu@172.16.0.1

    I don’t know if software which should be installed from the repository are required for that.
