OpenStack Victoria : Configure Neutron #22021/08/31 |
|
Configure OpenStack Network Service (Neutron).
This example is based on the emvironment like follows.
If you'd like to install Neutron services on another Host, refer to here.
Neutron needs a plugin software, it's possible to choose it from some softwares.
This example chooses ML2 plugin. ( it uses LinuxBridge under the backend )
eth0|10.0.0.30
+-----------+-----------+
| [ Control Node ] |
| |
| MariaDB RabbitMQ |
| Memcached httpd |
| Keystone Glance |
| Nova API,Compute |
| Neutron Server |
| L2,L3,Metadata Agent |
+-----------------------+
|
| [1] | Install Neutron services. For questions duruing the installation, it's OK with [No] to all. |
