OpenStack Liberty : Configure Neutron (Compute Node)2015/12/27 |
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. ( this example selects LinuxBridge as a backend for the plugin )
| +------------------+ | +------------------------+ | [ 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 | +------------------+ | +------------------------+ eth0|10.0.0.51 +--------------------+ | [ Compute Node ] | | Nova Compute | | L2 Agent | +--------------------+ |
