OpenStack Newton : Configure Neutron#4 ( Network Node )2017/07/02 |
|
Configure OpenStack Network Service (Neutron).
This example is not All in One Settings like here, but Configure the 3 Nodes environment like follows.
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 )

| [2] | Install Neutron services for Network Node. For selection during the installation, select [No] to all or input any value (because create a new conf file later). |
