OpenStack Mitaka : Configure Neutron#3 (Compute Node)2016/05/28 |
|
Configure OpenStack Network Service (Neutron).
For this example, Install Neutron Server on Control Node which Keystone/Glance/Nova API are already installed,
and Install DHCP Agent, L3 Agent, L2 Agent, Metadata Agent on Network Node, and also Install L2 Agent on Compute Node on here.
( it's possible to install on a server as All-in-One, though, if you want )
Neutron needs a plugin software, it's possible to choose it from some softwares. This example chooses ML2 plugin.
( this example selects LinuxBridge as a backend for the plugin )
