名词介绍

网络虚拟化重点

Linux Bridge || open vswitch

vxlan技术

主要通过udp封装原始报文，减少二层网络因为链路带来的带宽消耗

SDN

软件定义网络（Software Defined Network）：将数据层面和控制层面剥离，控制层面下发转发策略；数据层面进行转发数据；我们不需要再去关心底层数据网络是什么样的。
软件sdn；硬件sdn

openflow

是开源的sdn网络协议（了解）

opendaylight

是开源的sdn软件（每一家厂商其实对SDN定义的标准也不同）

【控制节点】

官方文档：https://docs.openstack.org/neutron/queens/install/controller-install-rdo.html

创建neutron数据库

`mysql -uroot -p000000`

创建数据库neutron用户，并进行授权

MariaDB [(none)] CREATE DATABASE neutron;
    MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' \
 IDENTIFIED BY '000000';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' \
 IDENTIFIED BY '000000';

创建neutron用户（service组），并赋予admin角色

source admin-openrc
openstack user create --domain default --password-prompt neutron
返回：

[root@controller ~]# openstack user create --domain default --password-prompt neutron
User Password:
Repeat User Password:

| password_expires_at | None                             |
+---------------------+----------------------------------+

openstack role add --project service --user neutron admin

创建neutron服务，并创建相应的endpoint

openstack service create --name neutron \
--description "OpenStack Networking" network

[root@controller ~]# openstack role add --project service --user neutron admin
[root@controller ~]# openstack service create --name neutron \
>  --description "OpenStack Networking" network
