openstack service create 出错

我创建

• $ export OS_TOKEN=8f811e26b38f09170581
  
  
• 配置端点URL：
  $ export OS_URL=http://controller:35357/v3
  
  
• 配置认证 API 版本：
  $ export OS_IDENTITY_API_VERSION=3
  
  
• openstack service create \  --name keystone --description "OpenStack Identity" identity
• 然后出错了
  

[root@openstack logs]# export OS_TOKEN=8f811e26b38f09170581
[root@openstack logs]# export OS_URL=http://controller:35357/v3
[root@openstack logs]# export OS_IDENTITY_API_VERSION=3

哪个版本的，最好参考官网。openstack应该一个环境变量配置的文件，直接生效即可。
最好贴出图来看下。
