[one-users] OCCI Server 0.3

Thu Aug 25 03:28:39 PDT 2011

You're getting closer :-)

The problem seems to be, that you have templates defined in your OpenNebula, but the OCCI server seems to have a bug when creating OCCI templates from them. I couldn't test the fix right now, but you may try out the following:
edit lib/occi/backend/OpenNebulaBackend.rb
add the following line at the end of require statements (e.g. after line 30):
require 'occi/infrastructure/ResourceTemplate'

If it is working, then everything is fine. Otherwise you may try to delete all templates in your OpenNebula installation and see if it works then. Only do this, if it is a test installation without any important VMs or services running.

Regarding the error with /usr/lib/one/ruby/cloud/occi/occi-server.rb you shouldn't run bin/occi-server server anymore. That's the old occi server included in OpenNebula, but it is outdated and cannot be run alongside the OGF OCCI server. In the first versions (0.1 and 0.2) of OGF OCCI I replaced that file with a new one, but for several reasons, it is a better idea to keep the OCCI code and the OpenNebula 3.0 code separate – at least until both are released in a stable version.

Cheers,
Florian

You are right, by changing the name it solved this problem…but I still get other problems.
Now when I start passenger it shows a list of all my Opennebula objects, i.e., VM, Storage, Image, etc… but an error appear after. Bellow I send you the final part of passenger’s output:

Ah, this is a problem between ruby and some operating systems. Some OS are case sensitive for ruby requires and others aren't. Unfortunately, I seem to have packaged the v0.3 packages with an OpenNebula folder containing uppercase letters. This is probably the cause of your problem. Please rename the folder lib/OpenNebula to lib/opennebula and tell me if this solved your problem.

Cheers,
Florian

Hi,

Thanks. Indeed, starting passenger in the OGF OCCI folder solves that problem but another one comes up:

      You can stop Phusion Passenger Standalone by pressing Ctrl-C.

Hi,

it looks like you successfully installed passenger. You should issue the

passenger command within the OGF OCCI folder. If you just start passenger,

it does not know, which files to serve and thus the error.

Please follow these steps (from the OGF OCCI Wiki):

3.) Download ogf-occi-0.3_beta2.tar.bz2 or ogf-occi-0.3_beta2.zip from

http://dev.opennebula.org/projects/ogf-occi/files

4.) Untar / unzip the file

5.) Change to the folder ogf-occi

6.) Change the configuration in etc/occi-server.conf

7.) Run the OCCI server with

passenger start

Cheers,

Florian
