OpenStack Dalmatian : Configure Neutron (Network Node)2024/10/10 |
Configure OpenStack Network Service (Neutron).
This example is not on the All in One Settings like here, but Configure the 3 Nodes environment like follows. ------------+--------------------------+--------------------------+------------ | | | 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 | | | | | +-----------------------+ +-----------------------+ +-----------------------+ |
[1] | Configure OpenStack Dalmatian repository like [3] of here and Install Neutron services on Network Node. |
