核心原理​

API/CLI​

OpenStack CLI是比较通用的云设施命令行工具。

安装​

以Python3环境为例，通过PIP安装 OpenStack CLI

pip3 install python-openstackclient
openstack --help
openstack help server create

#更新
pip3 install --upgrade  python-openstackclient

#强制更新
pip3 install --upgrade --force-reinstall python-openstackclient

常见命令​

#先通过 source /root/.huawei/config_zh 引入环境变量，然后再操作下列命令：

#查询服务器型号
openstack flavor list

#列出当前所有服务器
openstack server list

#列出所有区域
openstack region list

#以json格式输出所有镜像
openstack image list -f json

#列出所有公共镜像
openstack image list --public

常见问题​

nova 与 openstack 命令有什么区别？​

OpenStackClient 项目设有统一命令行客户端（Unified CLI），即 openstack
同时，每一项服务也有一个独立的命令行客户端（Individual CLI）。例如，Compute 服务 nova

OpenStack CLI中的port是什么？​

port就是虚拟网卡，包括：ID号，MAC地址，内网IP、公网IP等信息。
