OpenStack Epoxy : Configure Neutron (Compute Node)

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 ) ------------+--------------------------+--------------------------+------------ | | | eth0|10.0.0.30 eth0|10.0.0.50 eth0|10.0.0.51 +-----------+-----------+ +-----------+-----------+ +-----------+-----------+ | [ dlp.srv.world ] | | [ network.srv.world ] | | [ node01.srv.world ] | | (Control Node) | | (Network Node) | | (Compute Node) | | | | | | | | MariaDB RabbitMQ | | Neutron L2/L3 Agent | | Libvirt | | Memcached Nginx | | Neutron Metadata | | Nova Compute | | Keystone httpd | | Open vSwitch | | Neutron L2 Agent | | Glance Nova API | | | | Open vSwitch | | Neutron Server | | | | | | Neutron Metadata | | | | | +-----------------------+ +-----------------------+ +-----------------------+ * Refer to here for settings of Nova Compute on Compute Node

[1]	Install Neutron services on Compute Node.

root@node01:~#  apt -y install neutron-common neutron-plugin-ml2 neutron-openvswitch-agent neutron-metadata-agent

[2]	Configure Compute Node.
