KATO Tomoyuki 31b31410f9 Factor out Install Guide for Debian with debconf 
To simplify the build tool chain,
factor out Install Guide for Debian with debconf.
Continueously, keep Install Guide for Debian without debconf
in the doc/install-guide directory. Also, use the contents
at doc/install-guide as possible for consistency.

On the following patches, clean up doc/install-guide sources
to cleanup the contents and build tool chains.

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.

    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]
...
vncserver_listen = $my_ip
vncserver_proxyclient_address = $my_ip

    • 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
