Controller Node installieren und konfigurieren¶

Installieren und konfigurieren von Komponenten¶

1. Installieren Sie die Pakete:

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

   Aufforderungen von debconf beantworten.

   Bemerkung

   nova-api-metadata is included in the nova-api package, and can be selected through debconf.

   Bemerkung

   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. Bearbeiten Sie die Datei /etc/nova/nova.conf und führen folgende Schritte durch:

   • 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
     

   • Aktivieren Sie die Unterstützung für den Netzwerkdienst in der [DEFAULT] Sektion:

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

     Bemerkung

     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
     

   • Konfigurieren Sie den Ort der Abbilddienst API in der Sektion [glance]:

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

Installation abschließen¶

• Restart des Compute Servcies:

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