本文档介绍了如何安装OpenStack的Dashboard组件，并提供了修改配置以允许所有客户端访问的步骤。此外，还展示了使用`ip netns`命令查看命名空间以及通过命名空间检查路由器端口的方法，为理解OpenStack网络管理提供帮助。
Dashboard:
- 安装dashboard相关的软件包:
# yum install openstack-dashboard httpd mod_wsgi -y
- 修改dashboard的配置文件：
# /etc/openstack-dashboard/local_settings
* 表示允许所有客户端访问
- 重启httpd服务即可。
命名空间：
- # ip netns
|
[root@neutron network-scripts]# ip netns qrouter-8031f9b4-bc30-46f3-9643-7c7a50e94672 qdhcp-199831c6-a8db-483d-9b3a-80cf17aca194 qdhcp-6f55c498-4e45-49f7-9c32-b76c766c5635 |
- 查看路由器上的port：
# ip netns exec qrouter-8031f9b4-bc30-46f3-9643-7c7a50e94672 ip a
|
