Cyclades Setup

++++++++++++++

The following apply to ``cyclades`` node. In the rest of the sections

we will refer to its IP with FQDN ``cyclades.example.com``.Please make sure you have

db, mq, gunicorn, apache, webproject, pithos and astakos already setup.

Install the corresponding package. Please note that memcache is needed for

versions >= 0.13 :

.. code-block:: console

    # apt-get install memcached

    # apt-get install python-memcache

    # apt-get install kamaki

    # apt-get install snf-pithos-backend

    # apt-get install snf-cyclades-app

In `/etc/synnefo/cyclades.conf` add:

    }

XXXXXXXX is the token for cyclades registered service and can be found

in astakos node running:

.. code-block:: console

   snf-manage service-list

Restart services and initialize database:

.. code-block:: console

   # /etc/init.d/gunicorn restart

   # /etc/init.d/apache2 restart

   # snf-manage syncdb

   # snf-manage migrate --delete-ghost-migrations

   # snf-manage loaddata flavors

Enable dispatcher:

.. code-block:: console

   # sed -i 's/false/true/' /etc/default/snf-dispatcher

   # /etc/init.d/snf-dispatcher start

In order end-user to have access to the VM's console:

.. code-block:: console

   # apt-get install snf-vncauthproxy

Edit `/etc/default/vncauthproxy`:

.. code-block:: console

   CHUID="www-data:nogroup"

At this point you should setup a :ref:`backend <i-backends>`. Please refer to the

coresponding section.  Here we assume that at least one backend is up and running,

so we can add it in Cyclades with:

.. code-block:: console

   # snf-manage backend-add --clustername=ganeti.example.com --user=synnefo --pass=example_rapi_passw0rd

After 0.13 every backend added stays in drained mode (no VMs can be added).

Therefore get your backend ID (propably 1) and run:

.. code-block:: console

   # snf-manage backend-list

   # snf-manage backend-modify --drained=False 1

Further assumptions:

- Preprovisioned Bridges: ``br0``, ``prv0``, ``prv1..prv20``

- Available "public" Subnet: ``10.0.1.0/24``

- Available "public" Gateway: ``10.0.1.1``

- Connectivity link for public network: ``br0``

Here admin has to define two different resource pools in Synnefo:

 - MAC prefix Pool

 - Bridge Pool

.. code-block:: console

   # snf-manage pool-create --type=mac-prefix --base=aa:00:0 --size=65536

   # snf-manage pool-create --type=bridge --base=prv --size=20

Add the synnefo setting in :file:`/etc/synnefo/cyclades.conf`:

.. code-block:: console

   DEFAULT_MAC_FILTERED_BRIDGE = 'prv0'

Add public network where the VM's will eventually connect to in order to

access Internet:

.. code-block:: console

   # snf-manage network-create --subnet=10.0.1.0/24 --gateway=10.0.1.1 --public --dhcp --flavor=CUSTOM --mode=bridged --link=br0 --name=Internet --backend-id=1

Test your Setup:

++++++++++++++++

In cyclades node run:

.. code-block:: console

    snf-manage backend-list

    snf-manage network-list

    snf-manage server-list

Visit https://cyclades.example.com/ui/ and create a VM or network.
