OpenStack Newton : Configure Neutron#22017/07/02 |
|
Configure OpenStack Network Service (Neutron).
This example is based on the emvironment like follows.
If you'd like to install Neutron services on another Computer, refer to here.
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 )
eth0|10.0.0.30

| MariaDB RabbitMQ |
| Memcached httpd |
| Keystone Glance |

| Neutron Server |
| L2,L3,Metadata Agent |

|
| [1] | Install Neutron services. For selection during the installation, select [No] to all or input any value (because create a new conf file later). |
