OpenStack Newton : Configure Neutron#3 (Compute Node)2016/10/23 |
|
Configure OpenStack Network Service (Neutron).
For this example, Install Neutron Server on Control Node which Keystone/Glance/Nova API are already installed,
and Install DHCP Agent, L3 Agent, L2 Agent, Metadata Agent on Network Node, and also Install L2 Agent on Compute Node on here.
( it's possible to install on a server as All-in-One, though, if you want )
Neutron needs a plugin software, it's possible to choose it from some softwares.
This example chooses ML2 plugin. ( it uses Open vSwitch under the backend )

+------------------+ | +------------------------+
| [ Control Node ] | | | [ Network Node ] |
| Keystone |10.0.0.30 | 10.0.0.50| DHCP Agent |
| Glance |------------+------------| L3 Agent |
| Nova API |eth0 | eth0| L2 Agent |
| Neutron Server | | | Metadata Agent |
