Mitaka版本openstack只支持VXLAN的分布式部署配置

首先我们从官网了解一下openstack分布式部署的基本知识
http://docs.openstack.org/mitaka/networking-guide/scenario-dvr-ovs.html
基于以上我们简单从这几个方面了解分布式架构的特点：
网络层

服务层：

架构：

角度：

本次部署不包含vlan network,环境centos7,同时需要参考mitaka安装文档
http://docs.openstack.org/mitaka/install-guide-rdo/
我是将network server ，network agent，Controller 分别安装在不同的虚拟机中。

配置文件如下：
计算节点配置与启动服务
配置文件有：
nova.conf，neutron.conf，openvswitch_agent.ini，l3_agent.ini
启动服务有：
neutron-l3-agent.service
neutron-openvswitch-agent.service
openstack-nova-compute.service
libvirtd.service
