OpenStack Keystone如何同时开启V3和V2版本
[attach]98[/attach]
我们知道OpenStack 最新版本Newton，keystone是V3版本，由于之前存在V2版本的应用，如何同时兼容呢？主要需要操作以下四步：
1.获取domain ID
[root@openstack-control-node1 ~]# openstack domain list
+----------------------------------+---------+---------+----------------+
| ID | Name | Enabled | Description |
+----------------------------------+---------+---------+----------------+
| d0e436a913f94ec28f3a1892e0a7a240 | default | True | Default Domain |
+----------------------------------+---------+---------+----------------+
2.编写Keystone配置文件，设置default_domain_id[root@openstack-control-node1 ~]# vim /etc/keystone/keystone.conf [identity] # # From keystone # # This references the domain to use for all Identity API v2 requests (which are # not aware of domains). A domain with this ID will be created for you by # keystone-manage db_sync in migration 008. The domain referenced by this ID # cannot be deleted on the v3 API, to prevent accidentally breaking the v2 API. # There is nothing special about this domain, other than the fact that it must # exist to order to maintain support for your v2 clients. (string value) default_domain_id = d0e436a913f94ec28f3a1892e0a7a2403.同步数据库
su -s /bin/sh -c "keystone-manage db_sync" keystone4.重启Keystone服务
