Andreas Jaeger 2d44b2b36d Prepare for Sphinx 1.5 
The new sphinx version introduces some changes that break build:

* Warns if code cannot be parsed for highlighting. Fix the code so
  that it can be parsed, this includes uncommenting "..." lines.
  Note that not every config file is an ini-file.
  Also, the parser seems to have bugs and cannot parse all files.
  Fix mysql ini file and enable the parameter, see
http://dev.mysql.com/doc/refman/5.7/en/innodb-parameters.html#sysvar_innodb_file_per_table
* :option: works only with declared options, replace useage with
  simple ``.

This change only handles a few files, more to come later.

Install and configure controller node

This section describes how to install and configure the Compute service, code-named nova, on the controller node.

Install and configure components

  1. Install the packages:

    # apt-get install nova-api nova-conductor nova-consoleauth \
  nova-consoleproxy nova-scheduler python-novaclient

    Respond to prompts for database management <debconf/debconf-dbconfig-common>, Identity service credentials <debconf/debconf-keystone-authtoken>, service endpoint registration <debconf/debconf-api-endpoints>, and message broker credentials <debconf/debconf-rabbitmq>.

    Note

    nova-api-metadata is included in the nova-api package, and can be selected through debconf, or editing enabled_apis in the [DEFAULT] section of nova.conf.

    Note

    A unique nova-consoleproxy package provides the nova-novncproxy, nova-spicehtml5proxy, and nova-xvpvncproxy packages. To select packages, edit the /etc/default/nova-consoleproxy file or use the debconf interface. You can also manually edit the /etc/default/nova-consoleproxy file, and stop and start the console daemons.

  2. Edit the /etc/nova/nova.conf file and complete the following actions:

    • In the [DEFAULT] section, enable only the compute and metadata APIs:

      [DEFAULT]
# ...
enabled_apis = osapi_compute,metadata

    • The .config and .postinst maintainer scripts of the nova-common package detect automatically the IP address which goes in the my_ip directive of the [DEFAULT] section. This value will normally still be prompted, and you can check that it is correct in the nova.conf after nova-common is installed:

      [DEFAULT]
# ...
my_ip = 10.0.0.11

    • In the [DEFAULT] section, enable support for the Networking service:

      [DEFAULT]
# ...
use_neutron = True
firewall_driver = nova.virt.firewall.NoopFirewallDriver

      Note

      By default, Compute uses an internal firewall driver. Since the Networking service includes a firewall driver, you must disable the Compute firewall driver by using the nova.virt.firewall.NoopFirewallDriver firewall driver.

    • In the [vnc] section, configure the VNC proxy to use the management interface IP address of the controller node:

      [vnc]
enabled = true
# ...
vncserver_listen = $my_ip
vncserver_proxyclient_address = $my_ip

    • In the [spice] section, disable spice.

      [spice]
enabled = false

    • In the [glance] section, configure the location of the Image service API:

      [glance]
# ...
api_servers = http://controller:9292

Finalize installation

  • Restart the Compute services:

    # service nova-api restart
# service nova-consoleauth restart
# service nova-scheduler restart
# service nova-conductor restart
# service nova-novncproxy restart
