OpenStack Train : Configure Neutron#22019/10/25 |
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.
It selects ML2 plugin on this example. ( it uses Open vSwitch 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 | +-----------------------+ |
