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
