您可以自定义并使用以下示例脚本在多个 Linux 虚拟机 (Virtual Machine, VM) 上升级 Horizon Agent。此脚本会使用 SSH 在 Linux 虚拟机上运行命令。
要复制和粘贴不包含分页符的脚本内容，请使用此主题的 HTML 版本，您可以从位于 https://www.vmware.com/support/pubs/view_pubs.html 的 Horizon 7 文档页面找到该版本。
脚本输入
此脚本将读取一个输入文件，用于部署 Linux 桌面的示例 PowerCLI 脚本的输入文件中对此做了介绍。此脚本还会以交互方式要求提供以下信息：
- 接受 Horizon Agent EULA（最终用户许可协议）
- vCenter Server 的 IP 地址
- vCenter Server 的管理员登录名称
- vCenter Server 的管理员密码
- ESXi 主机的管理员登录名称
- ESXi 主机的管理员密码
- Linux 客户机操作系统的用户登录名称
- Linux 客户机操作系统的用户密码
- Horizon Agent tar ball 路径
- 升级到受管虚拟机
- 安装智能卡重定向功能
