我必须在settings.py中设置哪个变量来重定向nova服务url

Question

我正在安装openstack horizon。

当我检查git hub上的文档时，他们提到

OpenStack服务运行的最低要求包括:

• Nova(计算、api、调度、网络和卷服务)
• 梯形

但是我的nova, keystone和glance服务在其他机器上运行。

例如

:Horizon在192.168.1.1上运行，keystone、nova和glance在192.168.1.2上运行。

我必须在settings.py中设置哪个变量来指向该url?

我尝试了OPENSTACK_KEYSTONE_URL，但没有工作:(.

Answer 1

没有"NOVA_URL"设置。所有服务(nova、swift、glance等)的端点均由Keystone提供。在settings.py中只需要OPENSTACK_KEYSTONE_URL。

From the doc:

Keystone同时作为服务目录让其他OpenStack系统了解OpenStack服务的相关API端点在哪里。的特别是OpenStack Dashboard，大量使用服务目录，这是必须的

必须首先定义keystone中的所有服务:http://docs.openstack.org/developer/keystone/configuringservices.html

欢呼

Answer 2

要配置horizon从另一台主机访问数据，可以在openstack_dashboard/local/local_settings.py中设置OPENSTACK_HOST

这个常量的默认值是

OPENSTACK_HOST = "127.0.0.1"

如果您想从192.168.1.2获取数据，那么将其更改为

OPENSTACK_HOST = "192.168.1.2"

并重新启动地平线，它将返回来自另一个主机的数据
