创建 OpenStack 客户端环境脚本¶

The previous section used a combination of environment variables and command options to interact with the Identity service via the openstack client. To increase efficiency of client operations, OpenStack supports simple client environment scripts also known as OpenRC files. These scripts typically contain common options for all clients, but also support unique options. For more information, see the OpenStack End User Guide.

创建脚本¶

创建 admin 和 ``demo``项目和用户创建客户端环境变量脚本。本指南的接下来的部分会引用这些脚本，为客户端操作加载合适的的凭证。

注解

The paths of the client environment scripts are unrestricted. For convenience, you can place the scripts in any location, however ensure that they are accessible.

Create and edit the admin-openrc file and add the following content:

注解

The OpenStack client also supports using a clouds.yaml file. For more information, see the os-client-config.

export OS_PROJECT_DOMAIN_NAME=Default
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=ADMIN_PASS
export OS_AUTH_URL=http://controller:35357/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2

将 ADMIN_PASS 替换为你在认证服务中为 admin 用户选择的密码。

Create and edit the demo-openrc file and add the following content:

export OS_PROJECT_DOMAIN_NAME=Default
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_NAME=demo
export OS_USERNAME=demo
export OS_PASSWORD=DEMO_PASS
export OS_AUTH_URL=http://controller:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2

将 DEMO_PASS 替换为你在认证服务中为 demo 用户选择的密码。

使用脚本¶

使用特定租户和用户运行客户端，你可以在运行之前简单地加载相关客户端脚本。例如：

加载``admin-openrc``文件来身份认证服务的环境变量位置和``admin``项目和用户证书：
```
$ . admin-openrc
```

请求认证令牌:

$ openstack token issue
