# 这里解释一下
# 运行上面的指令会有如下结果：
# 1）在endpoint表增加3个服务实体的API端点
# 2）在local_user表中创建admin用户，密码adminpassword
# 3）创建了admin project和default域（默认域）
# 4）在role表创建3种角色，admin，member和reader
# openstack role list      # 查看角色

# openstack domain list     # 查看默认域

# openstack user list        # 查看用户
# openstack project list     # 查看项目
# 同理，可得默认的配置，图省略
