|
Configure OpenStack Network Service (Neutron).
This example is not 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 | | | | |
