Installation Guide - Remove database keys from Nova on compute node

[Matt Kassawara]

Nova on the compute node(s) should use AMQP instead of MySQL to communicate with Nova on the controller node. Consider removing the following keys from explicit configuration in nova.conf on the compute node:

[database]
connection = mysql://nova:NOVA_DBPASS@controller/nova

Fix proposed to branch: master

[Tom Fifield (fifieldt)]

from the review: this will break nova-network, unless conductor is fixed for multi host

[Matt Kassawara (ionosphere80)]

Contrary to nova patches addressing this issue, I still cannot get a compute node with nova-network to launch an instance without direct database access. I updated the associated nova bug:

Did RC2 fix this?

[Matt Kassawara (ionosphere80)]

Testing ASAP.

[Matt Kassawara (ionosphere80)]

Nova bug still valid on 2014.1.

[Matt Kassawara (ionosphere80)]

This appears resolved after testing Juno milestone 2 packages, so we can remove database configuration from the compute node(s).

    More updates for Juno

    I updated the installation guide for Juno as follows:

    1) Unifed RHEL/CentOS/Fedora steps to use systemd through
       networking chapter. Will work on other chapters in a
       future patch.
    2) Split openSUSE steps to use systemd.
    3) Removed database configuration from nova on compute
       nodes (yay!).
    4) Added workaround for RDO changing the neutron default
       "auth_strategy=keystone" back to "auth_strategy=noauth".
    5) Re-add workaround for broken RDO neutron init scripts. See
       bug #1375746 for more information.
    6) Applied other changes for RHEL/CentOS 7.
    7) Improved nova-network content.
    8) Other minor fixes.
