|
|
|
|
[database]
|
|
...
|
|
connection = mysql+pymysql://neutron:NEUTRON_DBPASS@controller/neutron
|
|
|
|
.. end
|
|
|
|
Replace ``NEUTRON_DBPASS`` with the password you chose for the
|
|
database.
|
|
|
|
* In the ``[DEFAULT]`` section, enable the Modular Layer 2 (ML2)
|
|
plug-in, router service, and overlapping IP addresses:
|
|
|
|
.. path /etc/neutron/neutron.conf
|
|
.. code-block:: ini
|
|
|
|
[DEFAULT]
|
|
...
|
|
core_plugin = ml2
|
|
service_plugins = router
|
|
allow_overlapping_ips = True
|
|
|
|
.. end
|
|
|
|
* In the ``[DEFAULT]`` and ``[oslo_messaging_rabbit]`` sections,
|
|
configure RabbitMQ message queue access:
|
|
|
|
.. path /etc/neutron/neutron.conf
|
|
.. code-block:: ini
|
|
|
|
[DEFAULT]
|
|
...
|
|
rpc_backend = rabbit
|
|
|
|
[oslo_messaging_rabbit]
|
|
...
|
|
rabbit_host = controller
|
|
rabbit_userid = openstack
|
|
rabbit_password = RABBIT_PASS
|
|
|
|
.. end
|
|
|
|
Replace ``RABBIT_PASS`` with the password you chose for the
|
|
``openstack`` account in RabbitMQ.
|
|
|
|
* In the ``[DEFAULT]`` and ``[keystone_authtoken]`` sections, configure
|
|
Identity service access:
|
|
|
|
.. path /etc/neutron/neutron.conf
|
|
.. code-block:: ini
|
|
|
|
[DEFAULT]
|
|
...
|
|
auth_strategy = keystone
|
|
|
|
[keystone_authtoken]
|
|
...
|
|
auth_uri = http://controller:5000
|
|
auth_url = http://controller:35357
|
|
memcached_servers = controller:11211
|
|
auth_type = password
|
|
project_domain_name = default
|
|
user_domain_name = default
|
|
project_name = service
|
|
username = neutron
|
|
password = NEUTRON_PASS
|
|
|
|
.. end
|
|
|
|
Replace ``NEUTRON_PASS`` with the password you chose for the ``neutron``
|
|
user in the Identity service.
|
|
|
|
.. note::
|
|
|
|
Comment out or remove any other options in the
|
|
``[keystone_authtoken]`` section.
|
|
|
|
* In the ``[DEFAULT]`` and ``[nova]`` sections, configure Networking to
|
|
notify Compute of network topology changes:
|
|
|
|
.. path /etc/neutron/neutron.conf

.. code-block:: ini
|
|
|
|
[DEFAULT]
|
|
...
|
|
notify_nova_on_port_status_changes = True
|
|
notify_nova_on_port_data_changes = True
|
|
|
|
[nova]
|
|
...
|
|
auth_url = http://controller:35357
|
|
auth_type = password
|
|
project_domain_name = default
|
|
user_domain_name = default
|
|
region_name = RegionOne
|
|
project_name = service
|
|
username = nova
|
|
password = NOVA_PASS
|
|
|
|
.. end
|
|
|
|
Replace ``NOVA_PASS`` with the password you chose for the ``nova``
|
|
user in the Identity service.
|
|
|
|
.. only:: rdo
|
|
|
|
* In the ``[oslo_concurrency]`` section, configure the lock path:
|
|
|
|
.. path /etc/neutron/neutron.conf
|
|
.. code-block:: ini
|
|
|
|
[oslo_concurrency]
|
|
...
|
|
lock_path = /var/lib/neutron/tmp
|
|
|
|
.. end
|
|
|
|
Configure the Modular Layer 2 (ML2) plug-in
|
|
-------------------------------------------
|
|
|
|
The ML2 plug-in uses the Linux bridge mechanism to build layer-2 (bridging
|
|
and switching) virtual networking infrastructure for instances.
|
|
|
|
* Edit the ``/etc/neutron/plugins/ml2/ml2_conf.ini`` file and complete the
|
|
following actions:
|
|
|
|
* In the ``[ml2]`` section, enable flat, VLAN, and VXLAN networks:
|
|
|
|
.. path /etc/neutron/plugins/ml2/ml2_conf.ini
|
|
.. code-block:: ini
|
|
|
|
[ml2]
|
|
...
|
|
type_drivers = flat,vlan,vxlan
|
|
|
|
.. end
|
|
|
|
* In the ``[ml2]`` section, enable VXLAN self-service networks:
|
|
|
|
.. path /etc/neutron/plugins/ml2/ml2_conf.ini
|
|
.. code-block:: ini
|
|
|
|
[ml2]
|
|
...
|
|
tenant_network_types = vxlan
|
|
|
|
.. end
|
|
|
|
* In the ``[ml2]`` section, enable the Linux bridge and layer-2 population
|
|
mechanisms:
|
|
|
|
.. path /etc/neutron/plugins/ml2/ml2_conf.ini
|
|
.. code-block:: ini
|
|
|
|
[ml2]
|
|
...
|
|
mechanism_drivers = linuxbridge,l2population
|
|
|
|
.. end
|
|
|
|
.. warning::
|
|
|
|
After you configure the ML2 plug-in, removing values in the
|
|
``type_drivers`` option can lead to database inconsistency.
|
|
|
|
.. note::
|
|
|
|
The Linux bridge agent only supports VXLAN overlay networks.
|
|
|
|
* In the ``[ml2]`` section, enable the port security extension driver:
|
|
|
|
.. path /etc/neutron/plugins/ml2/ml2_conf.ini
|
|
.. code-block:: ini
|
|
|
|
[ml2]
|
|
...
|
|
extension_drivers = port_security
|
|
|
|
.. end
|
|
|
|
* In the ``[ml2_type_flat]`` section, configure the provider virtual
|
|
network as a flat network:
|
|
|
|
.. path /etc/neutron/plugins/ml2/ml2_conf.ini
|
|
.. code-block:: ini
|
|
|
|
[ml2_type_flat]
|
|
...
|
|
flat_networks = provider
|
|
|
|
.. end
|
|
|
|
* In the ``[ml2_type_vxlan]`` section, configure the VXLAN network identifier
|
|
range for self-service networks:
|
|
|
|
.. path /etc/neutron/plugins/ml2/ml2_conf.ini
|
|
.. code-block:: ini
|
|
|
|
[ml2_type_vxlan]
|
|
...
|
|
vni_ranges = 1:1000
|
|
|
|
.. end
|
|
|
|
* In the ``[securitygroup]`` section, enable :term:`ipset` to increase
|
|
efficiency of security group rules:
|
|
|
|
.. path /etc/neutron/plugins/ml2/ml2_conf.ini
|
|
.. code-block:: ini
|
|
|
|
[securitygroup]
|
|
...
|
|
enable_ipset = True
|
|
|
|
.. end
|
|
|
|
Configure the Linux bridge agent
|
|
--------------------------------
|
|
|
|
The Linux bridge agent builds layer-2 (bridging and switching) virtual
|
|
networking infrastructure for instances and handles security groups.
|
|
|
|
* Edit the ``/etc/neutron/plugins/ml2/linuxbridge_agent.ini`` file and
|
|
complete the following actions:
|
|
|
|
* In the ``[linux_bridge]`` section, map the provider virtual network to the
|
|
provider physical network interface:
|
|
|
|
.. path /etc/neutron/plugins/ml2/linuxbridge_agent.ini
|
|
.. code-block:: ini
|
|
|
|
[linux_bridge]
|
|
physical_interface_mappings = provider:PROVIDER_INTERFACE_NAME
|
|
|
|
.. end
|
|
|
|
Replace ``PROVIDER_INTERFACE_NAME`` with the name of the underlying
|
|
provider physical network interface. See :ref:`environment-networking`
|
|
for more information.
|
|
|
|
* In the ``[vxlan]`` section, enable VXLAN overlay networks, configure the
|
|
IP address of the physical network interface that handles overlay
|
|
networks, and enable layer-2 population:
|
|
|
|
.. path /etc/neutron/plugins/ml2/linuxbridge_agent.ini
|
|
.. code-block:: ini
|
|
|
|
[vxlan]
|
|
enable_vxlan = True
|
|
local_ip = OVERLAY_INTERFACE_IP_ADDRESS
|
|
l2_population = True
|
|
|
|
.. end
|
|
|
|
Replace ``OVERLAY_INTERFACE_IP_ADDRESS`` with the IP address of the
|
|
underlying physical network interface that handles overlay networks. The
|
|
example architecture uses the management interface to tunnel traffic to
|
|
the other nodes. Therefore, replace ``OVERLAY_INTERFACE_IP_ADDRESS`` with
|
|
the management IP address of the controller node. See
|
|
:ref:`environment-networking` for more information.
|
|
|
|
* In the ``[securitygroup]`` section, enable security groups and
|
|
configure the Linux bridge :term:`iptables` firewall driver:
|
|
|
|
.. path /etc/neutron/plugins/ml2/linuxbridge_agent.ini
|
|
.. code-block:: ini
|
|
|
|
[securitygroup]
|
|
...
|
|
enable_security_group = True
|
|
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
|
|
|
|
.. end
|
|
|
|
Configure the layer-3 agent
|
|
---------------------------
|
|
|
|
The :term:`Layer-3 (L3) agent` provides routing and NAT services for
|
|
self-service virtual networks.
|
|
|
|
* Edit the ``/etc/neutron/l3_agent.ini`` file and complete the following
|
|
actions:
|
|
|
|
* In the ``[DEFAULT]`` section, configure the Linux bridge interface driver
|
|
and external network bridge:
|
|
|
|
.. path /etc/neutron/l3_agent.ini
|
|
.. code-block:: ini
|
|
|
|
[DEFAULT]
|
|
...
|
|
interface_driver = neutron.agent.linux.interface.BridgeInterfaceDriver
|
|
external_network_bridge =
|
|
|
|
.. end
|
|
|
|
.. note::
|
|
|
|
The ``external_network_bridge`` option intentionally lacks a value
|
|
to enable multiple external networks on a single agent.
|
|
|
|
Configure the DHCP agent
|
|
------------------------
|
|
|
|
The :term:`DHCP agent` provides DHCP services for virtual networks.
|
|
|
|
* Edit the ``/etc/neutron/dhcp_agent.ini`` file and complete the following
|
|
actions:
|
|
|
|
* In the ``[DEFAULT]`` section, configure the Linux bridge interface driver,
|
|
Dnsmasq DHCP driver, and enable isolated metadata so instances on provider
|
|
networks can access metadata over the network:
|
|
|
|
.. path /etc/neutron/dhcp_agent.ini
|
|
.. code-block:: ini
|
|
|
|
[DEFAULT]
|
|
...
|
|
interface_driver = neutron.agent.linux.interface.BridgeInterfaceDriver
|
|
dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq
|
|
enable_isolated_metadata = True
|
|
|
|
.. end
|
|
|
|
Return to
|
|
:ref:`Networking controller node configuration
|
|
<neutron-controller-metadata-agent>`.
