33.Region的概念及配置多region

- Region ---是用來標記不同的openstack 環境的

- 環境：

創建兩套packstack裝好的openstack 環境，然後修改其中的一個keystone認證到另外一個keystone上，兩套packstack的環境的Region 名字不同：

一個是RegionOne，一個是RegionTwo，來測試多region 環境登錄。

- 爲了將RegionOne的組件全部定義到RegionTwo，需要將RegionOne各個組件的endpoint重新在RegionTwo的環境上定義：（除了keystone）

- 之後修改RegionOne的各個服務的keystone認證地址：改成RegionTwo的keystone認證地址：

注意：需要將RegionTwo的keytone token複製到RegionOne各個服務配置文件的keystone認證賬號處。

admin_token = ee2aaac6c0d84b51a1d1f096d4540ada

- 只修改keystone認證相關的IP地址即可：

ceilometer--# vim /etc/ceilometer/ceilometer.conf

cinder--# vim /etc/cinder/cinder.conf

neutron--# vim /etc/neutron/neutron.conf

glance--# vim /etc/glance/glance-api.conf

# vim /etc/glance/glance-registry.conf

nova--# vim /etc/nova/nova.conf

- 修改之後重啓openstack服務：

# openstack-service restart

- 修改dashboard選項，允許多Region登錄：

- 此時登錄dashboard會出現muti-region登錄的提示和選項：

33.Region的概念及配置多region

4. [Instance&SecurityGroup]簡單配置嚮導及說明

12. 安裝及部署keystone

13. keystone v3 方式驗證

17.啓動swift服務並創建容器和對象

16.部署swift服務|swift配置存儲和ring

Mac下配置sublime實現LaTeX
