OpenStack - keystone 问题 'NoneType' object has no attribute 'service_catalog'

'NoneType' object has no attribute 'service_catalog' 报错

编辑：/etc/keystone/keystone-paste.ini
在[pipeline:public_api], [pipeline:admin_api], and [pipeline:api_v3] 三个地方
移走：admin_token_auth

为了安全设置，需要移除认证中的 token相关的认证，可以移除之后，使用admin进行验证的时候报错：

[root@controller01 ~]# openstack --os-auth-url http://controller01:35357/v3 --os-project-domain-name default --os-user-domain-name default --os-project-name admin --os-username admin token 
issue'NoneType' object has no attribute 'service_catalog'

研究后发现是之前在使用token的时候，定义了系统的环境变量，移除后再试就好了：
操作如下：

[root@controller01 ~]# unset OS_TOKEN
[root@controller01 ~]# unset OS_URL
[root@controller01 ~]# unset OS_IDENTITY_API_VERSION
[root@controller01 ~]# echo ${OS_TOKEN}

[root@controller01 ~]# openstack --os-auth-url http://controller01:35357/v3 --os-project-domain-name default --os-user-domain-name default --os-project-name admin --os-username admin token
