控制端服务

#： 创建库，并授权

MariaDB [(none)]> CREATE DATABASE neutron;
Query OK, 1 row affected (0.001 sec)

MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' \
    ->   IDENTIFIED BY 'neutron123';

#：导入环境变量

[root@cobbler ~]# source scripts/admin-stein.sh

#：创建neutron用户

[root@cobbler ~]# openstack user create --domain default --password-prompt neutron

#：为admin项目添加一个用户neutron，并添加至service角色

[root@cobbler ~]# openstack role add --project service --user neutron admin

#：创建一个network的项目
[root@cobbler ~]# openstack service create --name neutron   --description "OpenStack Networking" network

#：注册api
[root@cobbler ~]# openstack endpoint create --region RegionOne network public http://www.magedu.net:9696
